Java流程控制08：For循环

for循环

for(i = 1;i<=100;i++){
    sum = sum + i;
}

1到100求和

public class ForDemo04 {
    //for(初始条件;判断条件;迭代条件){}
    public static void main(String[] args) {
        int i;
        int sum = 0;
        for(i = 1;i<=100;i++){
            sum = sum + i;
        }
        System.out.println(sum);
