php用while循环求偶数和,算法之求1到100（奇数、偶数）的和（for和while循环）

目录

一、1到100所有数的和

1、for循环实现

public class Sum100 {

public static void main(String[] args) {

int sum = 0;

for (int i = 1; i

public static void main(String[] args) {

int sum = 0;

int i = 1;

while(i

public static void main(String[] args) {

int sum = 0;

int i = 1;

while (i

sum += i;

}

i++;

}

System.out.println(sum);

}

}

2、for循环方式

public class Sum100 {

public static void main(String[] args) {

int sum = 0;

for (int i = 1; i

public static void main(String[] args) {

int sum = 0;

for (int i = 1; i

public static void main(String[] args) {

int sum = 0;

int i = 2;

while (i
