Unexpected error with my class

Question

When writing a class it is giving me an expected token error and I can not figure out how to solve it or why it is giving it to me.

Here's the code:

public class SetUpDoors {
private int DoorAmount;
private int WinningDoorAmount; 
private int[] DoorArray= new int[DoorAmount];
private int winnerSelect = 0;
for (int i = 0; i < DoorAmount; i++) {
 if (WinningDoorAmount > 0) {
 winnerSelect = (int) Math.round( Math.random());
 DoorArray[i] = winnerSelect;
 if(winnerSelect == 1) {
 WinningDoorAmount--;
 }
 }
 else {
 DoorArray[i] = 0;
 }
 DoorAmount--;
}
void setDoorAmount(int userDoors){
 DoorAmount = userDoors;
}
void setWinningDoorAmount(int userWinningDoors) {
 WinningDoorAmount = userWinningDoors;
}

}

it is giving the error on the ; at the end of private int winnerSelect = 0; and an error for the } right below DoorAmount--; The first is expected token "{" and the second is add "}" to complete block.

• assylias: The for loop needs to be inside a method...
• shmosel: You can't just dump code in a class, you need a method.

Answer 1

You must declare following code inside a method.

For example:

public void newMethod(){
 for (int i = 0; i < DoorAmount; i++) {
 if (WinningDoorAmount > 0) {
 winnerSelect = (int) Math.round( Math.random());
 DoorArray[i] = winnerSelect;
 if(winnerSelect == 1) {
 WinningDoorAmount--;
 }
 }
 }
 else {
 DoorArray[i] = 0;
 }
 DoorAmount--;
}

Answer 2

try this

public class SetUpDoors {
 private int DoorAmount;
 private int WinningDoorAmount; 
 private int[] DoorArray= new int[DoorAmount];
 private int winnerSelect = 0;
 {
 for (int i = 0; i < DoorAmount; i++) {
 if (WinningDoorAmount > 0) {
 winnerSelect = (int) Math.round( Math.random());
 DoorArray[i] = winnerSelect;
 if(winnerSelect == 1) {
 WinningDoorAmount--;
 }
 }
 else {
 DoorArray[i] = 0;
 }
 DoorAmount--;
 }
 }
 void setDoorAmount(int userDoors){
 DoorAmount = userDoors;
 }
 void setWinningDoorAmount(int userWinningDoors) {
 WinningDoorAmount = userWinningDoors;
 }
}
