Efficient implementation for: "Python For Else Loop" in Java

Question

In Python there is an efficient for else loop implementation described here

Example code:

for x in range(2, n):     if n % x == 0:         print n, 'equals', x, '*', n/x         break else:     # loop fell through without finding a factor     print n, 'is a prime number' 

In Java I need to write more code to achieve the same behavior:

finishedForLoop = true; for (int x : rangeListOfIntegers){     if (n % x == 0)     {         //syso: Some printing here         finishedForLoop = false         break;     } } if (finishedForLoop == true){     //syso: Some printing here } 

Is there any better implementation similar to Python for else loop in Java?

Answer 1

It's done like this:

class A {     public static void main(String[] args) {         int n = 13;         found: {             for (int x : new int[]{2,3,4,5,6,7,8,9,10,11,12})                 if (n % x == 0) {                     System.out.println("" + n + " equals " + x + "*" + (n/x));                     break found;                 }             System.out.println("" + n + " is a prime number");         }     } }

$ javac A.java && java A 13 is a prime number
