Question

java语言用while循环语句 从1加到100

Answer 1

public class Test {
public static void main(String[] args){
int i=1;
int sum=0;
while (i<=100)
{
sum += i;
i++;
}
System.out.println(sum);
}
}

Answer 2

int i=1,sum=0;
while(i<=100){
sum+=i;
i++;
}

Answer 3

import java.io.*;
public class JiaFa {
public static void main(String args[]){
int i=1;
int he=0;
while (i<=100)
{
he=he+i;
i++;
}
System.out.println(he);

}
}

Answer 4

public class Sun {
public static void main(String[] args) {
int num = 0; //累加器
int i = 1;
while(i<=100){ //如果i小于等于100运行num + i
num = num + i;
i++; //i++ 每次加一
}
System.out.println(num); //最后打印结果
}
}

Answer 5

public class TestJava{
public static void main(String[] args){
int sum=0;
for(int i=1;i<=100;i++){
sum+=i;
}
System.out.println(sum);
}
}
