./Player.java:59: error: unexpected type

^
required: variable

./Player.java:68: error: unexpected type
getHitPoints() -= enemyATK;
I know this is wrong, but what is the reason behind this? Also I have
public void increaseHitPoints(){
}
public void decreaseHitPoints(){
}
these two class in my character class, I don't how to code to make this work.

getHitPoints() is a method that returns a value. You can't assign anything to that expression, and the -= operator performs both subtraction and assignment.
Instead of
getHitPoints() -= playerATK;
write
setHitPoints (getHitPoints() - playerATK);
or
decreaseHitPointsBy (playerATK); // this approach would require a corresponding
// increaseHitPointsBy (value) method

Having trouble reseting game to previous round JAVA

I made a program which asks the user for their pet name and assigns it states of mind for 5 rounds. If the pet gets too angry it is put down.
What I am having trouble with is allowing the user to restart to an earlier stage at the game before the pet died.
Compiling the code would help illustrate the issue.
Any help would be appreciated.

First of all you should look at the compile errors in your code before submitting a question here.
Please read the links provided in the comments to learn how to submit a proper question.
I tried to compile your code and it had the following errors:
java2.java:51: error: '.class' expected
emotionalstate = wheretogo(emotionalstate[]);
^
java2.java:75: error: '(' or '[' expected
Scanner scanner = new scanner;
That means in line 51, you're passing emotionalstate[] , which is emotional state array, whereas emotionalstate itself is an array, so you're passing an array of an array.
So just change it to emotionalstate = wheretogo(emotionalstate)
And in line 75, your initialization of Scanner object is wrong, change it to Scanner scanner = new Scanner();

quadratics methods in java displaying complex roots

everyone so I'm writting a program that solves quadratics (one doubled root and two doubled roots this seems to work but somehow I can't get it to solve complex roots? any help.
import javax.swing.JOptionPane;
public class QuadMethods {
static double a=0;
static double b=0;
static double c=0;
public static void main(String[] args) {
getUserInput(); // gets values into a, b, and c
double disc = getTheDiscriminant(a,b,c);
if (disc ==0) {
displayDoubledRealRoot(a,b,c);
//} else if (disc < 0) {
//displayComplexConjugates();
} else if (disc > 0) {
displayUnequalRealRoots(a,b,c);
//} else {
//System.out.println("Help! Arithmetic has failed!");
//
}
}
public static void displayUnequalRealRoots(double a, double b, double c) {
double disc = getTheDiscriminant(a,b,c);
double r1 = (-b+Math.sqrt(disc)/ (2*a));
double r2 = (-b-Math.sqrt(disc)/ (2*a));
String s = "two roots " + r1 + " and " + r2;
JOptionPane.showMessageDialog(null, s);
}
public static void displayDoubledRealRoot(double a, double b, double c) {
String s = "One doubled root = " + (-b/(2*a));
JOptionPane.showMessageDialog(null, s);
}
public static double getTheDiscriminant(double a, double b, double c) {
return b*b - 4*a*c;
}
public static void getUserInput() {
JOptionPane.showMessageDialog(null, "Getting coeffecients for ax^2+bx+c=0");
a = getANumber("a");
b = getANumber("b");
c = getANumber("c");
}
public static double getANumber(String p) {
boolean iDontHaveANumberYet = true;
double r = 0;
do {
try {
String aStr = JOptionPane.showInputDialog("Enter \"" + p + "\"");
r = Double.parseDouble(aStr);

} catch (Exception e) {

user input still stored after exceeding array length

Can someone see why the user can enter more than 27 apple, blueberry, or peanut pies? Even after declaring a final int for the max number of each type of pie.
The object here is to continually prompt the user for type of pie until the user wants to quit. Each time one of the valid inputs is entered it is stored in it's own array. After the user has indicated they are finished, calculations are done and a message is printed.
import javax.swing.JOptionPane;
public class CalcPieProfit {
public static void main(String[] args) {
final int MAX_PER_TYPE = 27;
int appleTotal = 0;
int blueberryTotal = 0;
int peanutTotal = 0;
String typeOfPie = getPieType();
while (!typeOfPie.equalsIgnoreCase("q")) {
if (typeOfPie.equalsIgnoreCase("apple")) {
String[] appleArray = fillApple(typeOfPie, MAX_PER_TYPE);
appleTotal++;
}
else if (typeOfPie.equalsIgnoreCase("blueberry")) {
String[] blueberryArray = fillBlueberry(typeOfPie, MAX_PER_TYPE);
blueberryTotal++;
}
else if (typeOfPie.equalsIgnoreCase("peanut")) {
String[] peanutArray = fillPeanut(typeOfPie, MAX_PER_TYPE);
peanutTotal++;
}
typeOfPie = getPieType();
}
if (typeOfPie.equalsIgnoreCase("q")) {
int totalPies = calcTotalPies(appleTotal, blueberryTotal, peanutTotal);
double profit = calcProfit(appleTotal, blueberryTotal, peanutTotal);
printReport(totalPies, appleTotal, blueberryTotal, peanutTotal, profit);
}
}
public static String getPieType() {

catch (NumberFormatException e) {
pieType = "";
}
if (!pieType.equalsIgnoreCase("apple") && !pieType.equalsIgnoreCase("blueberry") &&
!pieType.equalsIgnoreCase("peanut") && !pieType.equalsIgnoreCase("q")) {
JOptionPane.showMessageDialog(null, "Enter 'apple', 'blueberry', 'peanut', or 'q' only.");
}

return pieType;
}
public static String[] fillApple(String typeOfPie, int MAX_PER_TYPE) {
String[] appleArray = new String[MAX_PER_TYPE];
for (int i = 0; i < appleArray.length; i++) {
appleArray[i] = typeOfPie;
}
return appleArray;
}
public static String[] fillBlueberry(String typeOfPie, int MAX_PER_TYPE) {
String[] blueberryArray = new String[MAX_PER_TYPE];
for (int i = 0; i < blueberryArray.length; i++) {
blueberryArray[i] = typeOfPie;
}

}

final double PEANUT_PROFIT = 6.95;
double profit = (APPLE_PROFIT * appleTotal) + (BLUEBERRY_PROFIT * blueberryTotal) +
(PEANUT_PROFIT * peanutTotal);
return profit;
}
public static void printReport(int totalPies, int appleTotal, int blueberryTotal, int peanutTotal, double profit) {

}
else {

}
}
}

You are not really using the String[]s appleArray, blueberryArray and peanutArray - they are created in their respective method but not used anywhere else. For calculating the profits, you are (rightfully) only the total variables.
Instead of
if (typeOfPie.equalsIgnoreCase("apple")) {
String[] appleArray = fillApple(typeOfPie, MAX_PER_TYPE);
appleTotal++;
}
you should do something like
if (typeOfPie.equalsIgnoreCase("apple")) {
if (appleTotal >= MAX_PER_TYPE) {
JOptionPane.showMessageDialog(null, "Too many apples.");
} else {
appleTotal++;
}
}
(and the same for other pie types).

You're redeclaring the pie arrays each time you go to add them.
public static String[] fillApple(String typeOfPie, int MAX_PER_TYPE) {
String[] appleArray = new String[MAX_PER_TYPE];
for (int i = 0; i < appleArray.length; i++) {
appleArray[i] = typeOfPie;
}
return appleArray;
}
Each time you call this method, a new "appleArray" is generated. If you want it to persist between calls to this method, declare the appleArray as private static outside of the loop, and reference that instead.

Boolean if statement

public class Health
{
boolean dependency;
String insuranceOwner = "";
static final int basicHealthFee = 250;
static final int healthDiscount = 20;
public Health(boolean dependent, String insurance)
{
dependency = dependent;
insuranceOwner = insurance;
}
public double computeCost()
{
double healthFee;
if (dependency == true)
{
healthFee = basicHealthFee - (basicHealthFee * (healthDiscount/100.0));
}
else
{
healthFee = basicHealthFee;
}
return healthFee;
}
}
Health h34 = new Health(true, "Jim");
System.out.println("discount price: " + h34.computeCost());
When I enter in true as a parameter to the constructor, my computeCost method still runs the block as if dependency were to == false. Is there any reason why?

You're falling victim to integer division. 20/100 == 0, and anything multiplied by that is 0. To get around that, change your static final int declarations to doubles.
static final double basicHealthFee = 250D;
static final double healthDiscount = 20D;
That D defines a double literal.

You need to define basicHealthFee and healthDiscount as double. Since you've defined them as integers you have the equation: healthFee = basicHealthFee - (basicHealthFee * (healthDiscount/100)); which becomes basicHealthFee - ( basicHealthFee * (20/100)) which becomes basicHealthFee - (basicHealthFee * 0) -> basicHealthFee - 0.
The if statement taking its value from your constructor is correct.

Your problem is not related to boolean. It is due to the division of integers. Please change the program as follows.
static final double healthDiscount = 20d;
static final double basicHealthFee = 250d;
package com.stackoverflow.test;
