java 入门 if语句实例

1.求0到100的偶数和

public class  Test{
    public static void main(String[]args ){
        int sum=0;
        for( int i=0;i<=100;i++){
            if(i%2==0){
                sum+=i;
            }
        }
        System.out.println("0到100的偶数和"+sum);
    }
}

2.求出所有的水仙花数

package com;
public class Test {
    public static void main(String[] args) {
        
        for (int i = 100; i <= 999; i++) {
            
            int a = i % 10;
            int b = i / 10 % 10;
            int c = i / 100 % 10;
            
            if (a * a * a + b * b * b + c * c * c == i) {
                System.out.println("水仙花数" + i);
            }
        }
    }
}
