Interest not updating

It is meant to calculate interest and then put that into a table with years, interest, and new balance. For some reason the interest is not being calculated correctly and is not updating.
import java.util.Scanner;
import java.text.*;
public class Interest
{
public static void main(String[] args)
{
printIntro();
Scanner input = new Scanner(System.in);
System.out.print("Enter initial balance: ");
int balanceAmount = input.nextInt();
System.out.print("Enter interest rate: ");
double interestRate = input.nextDouble();
System.out.print("Enter the number of years: ");
int years = input.nextInt();
printTable(years, balanceAmount, interestRate);
}
public static double calcInterest(double balanceAmount, double interestRate, double years)
{
double interest = balanceAmount * Math.pow((1 + interestRate/100),years);
return interest;
}
public static void printRow(int rowNum, double balanceAmount, double interestRate)
{
System.out.println(rowNum + "\t" + balanceAmount + "\t" + "\t" + interestRate + "\t" + "\t" + (balanceAmount + interestRate));
//balanceAmount = (balanceAmount + interestRate);
}
public static void printTable(int numRows, double balanceAmount, double interestRate)
{
System.out.println("Year" + "\t" + "Balance" + "\t" + "\t" + "Interest" + "\t" + "New Balance");
System.out.println("----" + "\t" + "-------" + "\t" + "\t" + "--------" + "\t" + "-----------");
for (int i = 1; i <= numRows; i++)
{
printRow(i, balanceAmount, interestRate);
balanceAmount = (balanceAmount + interestRate);
}
}
public static void printIntro()
{
System.out.println("This program will calculate the interest "
+ "earned on a deposit over a certain amount of years.");
}
}

You should call your business logic to calculate interest as per your business requirement. That totaly depend on your business requirement.
Though for program specific it seems that You need to call your calcInterest method in printTable method, before you call your printRow method as below:
public static void printTable( final int numRows, double balanceAmount, final double interestRate ) {
System.out.println( "Year" + "\t" + "Balance" + "\t" + "\t" + "Interest" + "\t" + "New Balance" );
System.out.println( "----" + "\t" + "-------" + "\t" + "\t" + "--------" + "\t" + "-----------" );
for ( int i = 1; i <= numRows; i++ ) {
double interest = calcInterest( balanceAmount, interestRate, 1 );
printRow( i, balanceAmount, interest );
balanceAmount = ( balanceAmount + interest );
}
}
Also your formula to calculate interest is wrong. it should be
double interest = balanceAmount * Math.pow( ( 1 + interestRate / 100 ), years )-balanceAmount;
It will give out put as below:
This program will calculate the interest earned on a deposit over a certain amount of years.
This program will calculate the interest earned on a deposit over a certain amount of years.
Enter initial balance: 100
Enter interest rate: 10
Enter the number of years: 3
Year Balance Interest New Balance
---- ------- -------- -----------
1 100.0 10.000000000000014 110.00000000000001
2 110.00000000000001 23.100000000000037 133.10000000000005
3 133.10000000000005 44.05610000000007 177.15610000000012

You are not calling calcInterest.
You need to call that under the printRow method before the
System.out.println(rowNum + "\t" + balanceAmount + "\t" + "\t" + interestRate + "\t" + "\t" + (balanceAmount + interestRate));
line

Pizzas purchased program Java *FIXED*

Entry level java program that won't compile. Any help at all would be amazing! I really just need a quick review of my basic level code. I get errors for ints, booleans, and doubles. I've tried to rearrange them in multiple ways and i just can not get it to work. Also my Cheesy crust calculation to add it the total. Again super novice but would really enjoy the help!

Your problem is related to scopes:
if ( condition ) {
String topping = "topping";
}
System.out.println(topping);
Will not compile. (Your code is a bit more broad, but still)
The problem here is that topping is a local variable in the if-block, once the if-block is terminated, the variable doesn't exist anymore.
You need to fix it to something like:
String topping = "default";
if ( condition ) {
topping = "topping";
}
System.out.println(topping);

Here is the error free code you need. You just need to create the methods and write your logic in it.

Issues in your code:
1. You have not initialized the variables you have used.
2. You have declared the variables in if and else clause. When you are planning to re-use the variables, never initialize them inside as their scope is restricted to the block.
3. Also, you have used the same variable name toppings as String and int .

Repeated Output, have to end the program manually

I am a beginner and not tried the following program which is giving me repeated output.. I have to end the program manually in eclipse. Not able to figure out the problem. Please advice. Any other tips are welcome.
import java.util.Scanner;
public class Sales_Amount {
public static void main(String[] args) {
final double Base_Salary = 25000;
double Commission = 0;
double Total_Salary;
double X;
double Y;
Scanner input = new Scanner(System. in );
System.out.print("Enter Sales Amount: ");
double Sales = input.nextDouble();
while (Commission < 25001) {
if (Sales <= 5000); {
Total_Salary = Base_Salary + (0.08 * Sales);
System.out.print(" Total Salary for " + Sales + "worth of Sales is: " + Total_Salary);
}
if (Sales > 5000 && Sales < 10001); {
X = Sales - 5000;
Total_Salary = Base_Salary + (0.08 * 5000) + (0.10 * X);
System.out.print(" Total Salary for " + Sales + "worth of Sales is: " + Total_Salary);
}
if (Sales > 10001); {
Y = Sales - 10000;
Total_Salary = Base_Salary + (.08 * 5000) + (.10 * 10000) + (.12 * Y);
System.out.print(" Total Salary for " + Sales + "worth of Sales is: " + Total_Salary);
}
}
}
}

Add commission++ before the end of the loop.

Wrong output for the balance, service charges and the decimal format

The balance should take the initial balance and subtract or add the transamt depending on the tcode(1 is a withdraw and 2 is a deposit).
Service charges are $0.10 for a deposit and $0.15 for a check. If a check forces the balance to drop below $500.00, a service charge of $5.00 is assessed but only for the first time this happens. Anytime the balance drops below $50.00, the program should print a warning message. If a check results in a negative balance, an additional service charge of $10.00 should be assessed.
The decimal format for the balance should be "00000.##" for positive and "(00000.##)". I do not know how put the second one.

Have you tried something like:
if (amount >= 0.0) {
showMessageDialog(amount);
} else {
showMessageDialog('(' + Math.abs(amount) + ')');
}
That is simplified, but it gets the idea across.

Accepting multiple inputs loop

I've written a program in Java that does a series of calculations, basically a payroll program for four different types of employees. I'm having an issue trying to make it NOT exit after the input is completed.
For example: The user is asked how many employees are in the company. From there it should start asking what employee #1's type is (manager, hourly, etc...) then keep asking until the total employees are met, say for example 4. After each input it's okay for the employee's name and information to output.
Here's what I have thus far, which is an almost complete, working program. The only thing left is the part I described above.
Any resources to help me work out the solution are more valuable than rewriting my code.
Thanks!

You are not asking the "Number of Employees" from the User in your code.Hope this is what you want.

It would appear that you need a loop, I suggest you use a do-while loop - that is, something like,
boolean stop = false;
do {
// as before
// set stop to true to end the loop.
} while (!stop);
