java中利用while语句求1到100的奇数和

public class TestWhile{
    
    public static void main(String[] args){
        
        int i = 1;
        int sum = 0;
        while(i<100){
            sum+=i;
            i+=2;
        }
        
        System.out.println("1-100的奇数和为sum = "+sum);
        System.out.println("--------------------------------------- ");
        int j = 1;
        sum = 0;
        while(j <= 100){
            
            if(j%2 == 0){    
                sum+=j;
            }
             j++;      
        }        
        System.out.print("1-100的偶数数和为sum = "+sum);
    }
    
}
