for循环实现打印100以内的素数并求和

public class SumPrimeNum {
    public static void main(String[] args) {

        int sum=0;
        int count=0;

        for (int i = 2; i <100 ; i++) {
            for (int j = 2; j <=i ; j++) {
                if(i%j==0&&i!=j) {
                    break;
                }

                if(i%j==0&&i==j){
                        sum+=i;
                        System.out.print(i+" ");
                        count++;
                        if(count ==5){
                            System.out.println();
                            count=0;

                    }

                }

            }

        }
        System.out.println("sum="+sum);
    }
}

输出结果如图
