有效的实现：Java中的“ Python的其他循环”

这样做是这样的：

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 A13 is a prime number
