 Topic: Calculate the sum of 1 to 100 and output it.

public class Sum {

	public static void main(String[] args) {
		int i;
		int result = 0;
		i = 1;   //循环变量赋初值
		while(i <= 100){   //循环条件   当型
			//if (i%2 == 1)  //求奇数之和
			result = result + i;
			i++ ;
			//i=i+2;    //求奇数之和
		}
		System.out.println("1+2+3+....+100 = "+ result);
	}
