java编程求1-50内素数之和

public static void main(String[] args) {
int sss = 0;
for(int n=2;n<=100;n++) {
    int i = n;
    boolean f = true;
    int t = 0;
    for (int j = 2; j <= i - 1; j++) {
	if (i % j == 0) {
	    t = j;
	    f = false;
	    break;
	}
    }
    if (f) {
	System.out.printf("% 3d ",i);
	sss+=i;
    }
}
System.out.println();
System.out.printf("1-100内素数和是：%d%n",sss);
}

运行结果如下
