Java_利用continue来取质数

package first_1;

public class primeNumberTest2 {
    public static void main(String[] args) {
        
        
        int count = 0;
        label:for (int i = 2; i < 100000; i++) {
            for (int j = 2; j <= Math.sqrt(i); j++) {
                if (i % j == 0) {
                    continue label;
                }
            
            }
            count++;
        
        }
        System.out.println("质数的个数为：" + count);

    }
}
