java基础的编程代码 java基础的编程代码是什么( 二 )

public class sum {

//创建一个Scannerjava基础的编程代码的对象input
Scanner input = new Scanner(System.in);
//提示用户输入数据
System.out.print("请输入一个整数");
//将输入的值赋给n
int n = input.nextInt();
//定义变量接收计算后的和
int sum = 0;
//利用循环进行求和
for (int i = 0; i = n; i++) {
sum+=i;
}
//输出最后的和
System.out.println("从0一直到"+n+"的所有整数的和是:"+sum);
