帮我写一份Java从1到100之和的代码
时间: 2023-03-21 12:01:44 浏览: 78
当然可以!以下是一份Java代码,可以计算1到100的和:
```java
public class SumOneToHundred {
public static void main(String[] args) {
int sum = 0;
for (int i = 1; i <= 100; i++) {
sum += i;
}
System.out.println("1到100之和为:" + sum);
}
}
```
代码解释:
- `int sum = 0;`:在开始循环之前,初始化sum变量为0,用于存储1到100之和。
- `for (int i = 1; i <= 100; i++)`:使用for循环,从1开始计数,一直加到100,每次循环将i的值加入到sum变量中。
- `sum += i;`:每次循环将i的值加入到sum变量中。
- `System.out.println("1到100之和为:" + sum);`:最后输出1到100之和的值。
运行程序,输出结果应该是:
```
1到100之和为:5050
```
