If Else error in java code

I'm getting an error at the line

else break;

I think it might have to do with the location of the "{}"

public class Palindrome {

    private static String number;

    public static void main(String[] args) {
        display();
    }

    private static int getUserInput() {
        int inputNumber = 0;
        String answer = JOptionPane.showInputDialog(null, "Please enter a five digit number","Enter a number");
        inputNumber = Integer.parseInt(answer);

        if(number.length() !=5 ){
            JOptionPane.showMessageDialog(null,"Please enter a 5 digit number!","Try again",
            JOptionPane.PLAIN_MESSAGE);

        else break;
        }

        return inputNumber;
    }

    private static boolean check(){
        int inputNumber = getUserInput();
        int number = inputNumber;
        int[] myArray = new int[5];
        for (int i = 0; i < myArray.length; i++) {
            myArray[i] = (int) (number /(Math.pow(10,i)) % 10);
        }
        if(myArray[0] == myArray[4] && myArray[1] == myArray[3])
            return true;
        else
            return false;
    }

    public static boolean display(){

        "Excellent!",JOptionPane.INFORMATION_MESSAGE);
        } else
            JOptionPane.showMessageDialog(null,
                "Number is not a Palindrome!",
                "Sorry",
                JOptionPane.ERROR_MESSAGE);
            return false;

    }
}

Thanks

else cannot be part of if. So, change this -

if(number.length() !=5 )
{
    JOptionPane.showMessageDialog(null,"Please enter a 5 digit number!","Try again",
    JOptionPane.PLAIN_MESSAGE);
}
else break;

Also, I don't understand why you use break here ?

---

if(/*some condition*/){
}else{
     break;//invalid use of break it won't compile see below
}

you are writting else without matching if

moreover you can't break without loop or switch case

---

Also a note: code like "if (condition) return true; else return false;" can be substituted for "return condition;". Much cleaner.

There are two problems:

1. else statement is not associated with an if statement. You need to move it outside of the {} for the else
2. You are using a break outside of a while or for loop (or named statement).

If you are trying to exit the application, then you can use System.exit method. However a better approach is to return a value that states that the user did not select a value, e.g., -1 or null (change return type of method to Integer).

---

You cannot break; from a method, instead you must return from a method. However in your case it would appear you want a retry loop.

private static int getUserInput() {
  while(true) {
    String answer = JOptionPane.showInputDialog(null, "Please enter a five digit number","Enter a number");
    if(answer.length() == 5 ) 
        return Integer.parseInt(answer);
    JOptionPane.showMessageDialog(null,"Please enter a 5 digit number!","Try again",
        JOptionPane.PLAIN_MESSAGE);
 }
}
