求两数的和差

import java.util.Scanner;

public class Calculate
{
public static void main(String args[])
{
Scanner input=new Scanner(System.in);
int num1;
int num2;
int sum;
int subtract;

System.out.print("请输入第一个整数：");
num1=input.nextInt();

System.out.print("请输入第二个整数：");
num2=input.nextInt();

sum=num1+num2;
subtract=num1-num2;
System.out.printf("sum=%d\nsubtract=%d",sum,subtract);
}
}
