Write a program that produces images of Christmas trees as output. I don't know what the error is

My code is resulting in an infinite loop when i run it. Don't know whats wrong.

I have tried the code below. It compiles properly.
public class Project3_1 {
//declare SEGMENTS and HEIGHT
public static final int SEGMENTS = 4;
public static final int HEIGHT = 4;
public static final int TOTAL = (2*(SEGMENTS)) + (2*(HEIGHT)) - 3;
public static void TopTree(int SEGMENTS, int HEIGHT) {
for (int s = 1; s <= SEGMENTS; s++) {
for (int h = 1; h <= HEIGHT; h++) {
int ASTERISKS = ((2*s) + (2*h) - 3);
int SPACES = ((TOTAL - ASTERISKS)/2);
//spaces
for (int b = 1; b <= SPACES; b++) {
System.out.print(" ");
}
//Asterisks
for (int a = 1; a <= ASTERISKS; a++) {
System.out.print("*");
}
System.out.println();
}
}
}
public static void TreeBase() {
int x = (TOTAL - 7)/2;
for (int i = 1; i <= (TOTAL-1)/2; i++){
System.out.print(" ");
}
System.out.println("*");
for (int i = 1; i <= (TOTAL-1)/2; i++){
System.out.print(" ");
}
System.out.println("*");
for (int i = 1; i <= x; x++){
System.out.print(" ");
}
for (int i = 1; i <= 7; i++) {
System.out.print("*");
}
for (int i = 1; i <= (TOTAL - (x + 7)); i++) {
System.out.print(" ");
}
System.out.println("");
}
public static void main (String[] args){
TopTree(SEGMENTS, HEIGHT);
TreeBase();
}
}

Check your third for loop in TreeBase(), you increment the wrong variable. The code you posted runs fine for me, it just doesn't make that bottom line of asterisks due to that loop I mentioned not being correct. Once you fix that, you should be good

Pine tree in java with for loop

I wrote a pinetree drawer in java. First it asks for how tall the tree and after that, asks for how many times draw it under each other and at the end it draws the tree's trunk. If the first input is <= 0 it need to stop the whole program and print a message. If the first input is good, but the second input is also <= 0 then stop the program. What is the order to make it operate? Thanks in advance!
public static void main(String[] args) {
Scanner sc = new Scanner(System.in);
int height;
int stars;
int level;
System.out.println("Fenyőfarajzoló program.");
System.out.print("Kérem a magasságot: ");
height = sc.nextInt();
System.out.print("Kérem a szintek számát: ");
level = sc.nextInt();
int szelesseg = height - 1;
if (height <= 0) {
System.out.println("A magasság csak pozitív lehet.");
} else if (level <= 0) {
System.out.println("A szintek száma csak pozitív lehet.");
} else {
for (int h = 0; h < level; h++) {
stars = 1;
for (int i = 0; i < height; i++) {
for (int j = szelesseg; j > i; j--) {
System.out.print(" ");
}
for (int k = 0; k < stars; k++) {
System.out.print("*");
}
stars += 2;
System.out.println();
}
}
}
for (int talp = 1; talp <= 3; talp++) {
System.out.println(" ***");

int szelesseg = height - 1;
if (height <= 0) {
System.out.println("A magasság csak pozitív lehet.");
throw new Exception("height is negative");
}
if (level <= 0) {
System.out.println("A szintek száma csak pozitív lehet.");
throw new Exception("level is negative");
}

Creating a double mirrored triangle

I need help making a mirrored triangle like this:
* *
** **
*** ***
********
I can get each one seperatly, but I can't combine them.
public static void main(String[] args){
for( int i = 1; i <= 5; i++ ){
for( int j = 0; j < i; j++ ){
System.out.print("*");
}
System.out.println();
}
for(int i = 0; i < 6; i++)
{
for(int j = 5; j > 0; j--)
{
if(i < j)
System.out.print(" ");
else
System.out.print("*");
}
System.out.println();
}
}

You need to track the position from both sides to be able to show * at correct location. Here is the solution:
for (int i = 1; i <= 5; i++) {
for (int j = 1; j <= 10; j++) {
if (j <= i || j > 10 - i) {
System.out.print("*");
} else {
System.out.print(" ");
}
}
System.out.println();
}

You can do it using this code.
public class Test {
public void sizeOfTri(int triSize) { //Number of lines
int line = 1;
for(int i = 0; i < triSize; i++) { //Handles Each line
int temp = triSize * 2;
for(int j = 1; j < temp; j++) { //Handles Each space on the line
if(j <= line && j == triSize || j >= temp - line && j == triSize) { //For the very last line because it needs an extra *
System.out.print("**");
} else if(j <= line || j >= temp - line) { //For normal lines
System.out.print("*");
} else if(j == triSize) {
System.out.print(" "); //For the second to last line because it needs an extra space to make it look mirrored
} else { //For normal lines
System.out.print(" ");
}
}
System.out.println();
line++;
}
}
public static void main(String[] args) {
new Test().sizeOfTri(4);
}
}
I commented on next to if statements on which part does what. This will produce an output which looks like the below when run
* *
** **
*** ***
********

Although, all the above implementations are really good ones. I thought of doing it bit differently and make use of 2-D arrays.
package algorithms;
public class DrawMirror {
static void initialize(String[][] array){
for (int i=0; i<MAX_X; i++){
for (int j=0; j < MAX_Y; j++){
array[i][j] = " ";
}
}
}
static void draw(String[][] array, int x, int y){
for (int i=0; i < y; i++){
array[x][i] = "*";
array[x][MAX_Y-i-1] = "*";
}
}
final static int MAX_X = 4;
final static int MAX_Y = 8;
public static void main(String[] args) {
String[][] array = new String[MAX_X][MAX_Y];
initialize(array);
for (int i=0; i < MAX_X ; i++){
draw(array,i,i+1);
}
for( int i = 0; i < MAX_X; i++ ){
for( int j = 0; j < MAX_Y; j++ ){
System.out.print(array[i][j]);
}
System.out.println();
}
}
}

The following code is a function with variable height.
public static void printDoubleTriangle(int height) {
for(int i = 0; i < height; i++) {
for(int j = 0; j < 2*height; j++) {
if(j <= i || (2*height - j - 1) <= i) {
System.out.print("*");
} else {
System.out.print(" ");
}
}
System.out.println();
}
}

How to generate a star Triangle pattern using Java

How to print a star triangle pattern using java. Pattern is something like this
* ====> row 1
* *
* *
* *
* * * * *
it can be n number of rows and from second row onwards there is odd number of white spaces between 2 stars like, 1,3,5, and last row have all the stars each separated by one white space.
Below is the Code I was working on to print the triangle?
public class Triangle
{
public static void main(String[] args)
{
int row = 4;
int space =0;
System.out.println("*");
for (int i=1;i<row;i++)
{
System.out.print("*");
for(space=0;space<i;space = space+i)
{
System.out.print(" ");
}
System.out.print("*");
System.out.println();
}
enter code here
for(int i=0;i<=4;i++)
{
System.out.print("* ");
}
}
}
How do I proceed?

public class Triangle {
public static void DrawWithStars(int dimension)
{
if(dimension < 0)
{
//Assuming that a triangle with dimension = 0 is a dot....
System.out.println("No valid dimension");
}
else
{
//To print the first dimension - 1 rows
for (int i = 0; i < dimension; i++)
{
for (int j = 0; j < dimension - i; j++) {
System.out.print(" ");
}
//Print the dot of the row 1 at the end
if(i != 0)
System.out.print("*");
for (int j = 0; j < 2 * i - 1; j++) {
System.out.print(" ");
}
System.out.println("*");
}
//To print the last row
for (int i = 0; i < dimension; i++)
{
System.out.print("* ");
}
System.out.println("*");
}
}
}

package apple;
public class Triangle
{
public static void main(String...strings){
int midspace = -1;
int row = 4;
String star = "";
for(int y=row-1; y>0; y--){
for(int space = 1;space <= y ; space++){
System.out.print(" ");
}
System.out.print("*");
for(int i = midspace; i>0; i--)
System.out.print(" ");
midspace += 2;
star = (y!=row-1) ? "*":"";
System.out.println(star);
}
for(int y=((row*2)-1); y>0; y--){
System.out.print("*");
}
}
}

Looping Algorithm

How do I make this:
*******
-*****-
--***--
---*---
--***--
-*****-
*******
The following is my code that I have written to try to accomplish the above, but it is not working as expected:
public static void stars(/*int jmlBaris*/) {
for ( int i = 7; i >= 1; i-=2) {
for (int j = 1; j <= i; j++) {
System.out.print("*");
}
System.out.println("");
}
for (int i = 1; i <= 7; i+=2) {
for (int j = 1; j <= i; j++){
System.out.print("*");
}
System.out.println("");
}
}
public static void main(String[] args) {
stars();
}
}

This is how I might write it.
// three loops
public static void stars(int size) {
for (int y = 0; y < size; y++) {
for (int i = 0; i < y && i < size - y - 1; i++)
System.out.print(' ');
for (int i = Math.min(y, size - y - 1); i < Math.max(y + 1, size - y); i++)
System.out.print('*');
System.out.println();
}
}
or
// two loops
public static void stars(int size) {
for (int y = 0; y < size; y++) {
for (int x = 0; x < size; x++)
System.out.print(
(x >= y && x < size - y) ||
(x >= size - y - 1 && x <= y) ? '*' : ' ');
System.out.println();
}
}
or
// one loop
public static void stars(int size) {
for (int i = 0; i < size * size; i++) {
int y = i / size, x = i % size;
System.out.print(
(x >= y && x < size - y) ||
(x >= size - y - 1 && x <= y) ? '*' : ' ');
if (x == size - 1)
System.out.println();
}
}
Note: Whether this uses one, two or three loops, the time complexity is O(N^2). A simple way to determine this is the number of stars produced is O(N^2) no matter how it is done.

I would do something like this with substrings.
String a = "*******"; //7 stars
String blank = " "; //7 spaces
int j = 7;
for (int i = 0; i < 7; i++) {
if (i > j){
System.out.print(blank.substring(0,i));
System.out.println(a.substring(i,j));
}
else{
System.out.print(blank.substring(0,j));
System.out.println(a.substring(j,i));
}
j--;
}
System.out.println(a);
**Previous edit wouldn't have worked. Changes made.
This works.

Try something like this code I compiled on IDEOne (it seems to work, though):
http://ideone.com/9xZ1YB
class Main
{
public static void main(String[] args)
{
stars();
}
static void stars()
{
final int MAX_WIDTH = 7;
for (int i = 0; i < 7; ++i)
{
int width;
if (i < 3) width = MAX_WIDTH - i * 2;
else if (i > 3) width = (i - 3) * 2 + 1;
else width = 1;
// Before spaces
for (int j = 0; j < (MAX_WIDTH - width) / 2; ++j)
{
System.out.print(" ");
}
// Stars
for (int j = 0; j < width; ++j)
{
System.out.print("*");
}
// After spaces
for (int j = 0; j < (MAX_WIDTH - width) / 2; ++j)
{
System.out.print(" ");
}
System.out.println();
}
}
}

For a beginner in algorithms I would recommend you to break down the structure in sub-parts and then try to solve the pattern.
For this specific pattern it could be broken down into several triangles. Each triangle is then solved by different for loops as shown in the image below.
public static void printPattern(int num) {
// this loop generates first 4 lines
for (int i = 0; i < num / 2 + 1; i++) {
// draws the red triangle of '-'
for (int j = 0; j < i; j++) {
System.out.print("-");
}
// draws the green triangle of '*'
for (int j = i; j < num / 2 + 1; j++) {
System.out.print("*");
}
// draws the blue triangle of '*'
for (int j = i + 1; j < num / 2 + 1; j++) {
System.out.print("*");
}
// draws the orange triangle of '-'
for (int j = 0; j < i; j++) {
System.out.print("-");
}
System.out.println();
}
/* this loop generates last 3 lines */
for (int i = 0; i < num / 2; i++) {
// draws the green triangle of '-'
for (int j = i + 1; j < num / 2; j++) {
System.out.print("-");
}
// draws the red triangle of '*'
for (int j = 0; j < i + 2; j++) {
System.out.print("*");
}
// draws the orange triangle of '*'
for (int j = 0; j < i + 1; j++) {
System.out.print("*");
}
// draws the blue triangle of '-'
for (int j = i + 1; j < num / 2; j++) {
System.out.print("-");
}
System.out.println();
}
}
Using similar technique you could generate any pattern.

If I understood you right, your problem is to print indent in lines 2-7.
Imagine same problem with asterisk symbol replaced by 'x' and whitespace replaced by '-'. Then you need to draw
xxxxxxx
-xxxxx-
--xxx--
---x---
--xxx--
-xxxxx-
xxxxxxx
That means you should output 0, 1, 2 space(s) before asterisks in first, second, thrid strings respectively. I let details for you to figure them out.

public static void stars(/*int jmlBaris*/){
String starstr = "*";
String blank = "_";
int spaceBlank;;
for(int i=7; i>=1;i-=2){
spaceBlank = (7-i)*.5;
String starrep = StringUtils.repeat(starstr, i);
String blankrep = StrinUtils.repeat(blank, spacesBlank);
system.out.println(blankrep + starrep + blankrep);
}
for(int j=3 j<=7; j+=2){
spaceBlank = (7-j)*.5;
starrep = StringUtils.repeat(starstr, j);
String blankrep = StrinUtils.repeat(blank, spacesBlank);
system.out.println(blankrep + starrep + blankrep);
}
}
public static void main(String[] args){
stars();
}

You have little missing to put space on your code. I don't care about right space, who can see that? But left space is very important!!
Try this:
public static void stars(/*int jmlBaris*/) {
for ( int i = 7; i >= 1; i-=2) {
for (int k = 0; k < ((7-i) / 2); k++){ /* Missing Here */
System.out.print(" "); /* Missing Here */
} /* Missing Here */
for (int j = 1; j <= i; j++) {
System.out.print("*");
}
System.out.println("");
}
for (int i = 1; i <= 7; i+=2) {
for (int k = 0; k < ((7-i) / 2); k++){ /* Missing Here */
System.out.print(" "); /* Missing Here */
} /* Missing Here */
for (int j = 1; j <= i; j++){
System.out.print("*");
}
System.out.println("");
}
}

int N = 7;
for (int y=0; y<N; y++)
{
for (int x=0; x<N; x++)
System.out.print( (y-x)*(N-y-x-1)<=0 ? '*' : '-');
System.out.println();
}
or, more symmetrically,
int n = 3;
for (int y=-n; y<=n; y++)
{
for (int x=-n; x<=n; x++)
System.out.print( y*y>=x*x ? '*' : '-');
System.out.println();
}
