Question

用JAVA编写 输入2个整数 num1 和 num2，计算并输出它们的和、差、积、商与余数。

程序填空，不要改变与输入输出有关的语句。
输入2个整数 num1 和 num2，计算并输出它们的和、差、积、商与余数。
输入输出示例：括号内是说明
输入
5 3 (num1=5,num2=3)
输出
5+3=8
5-3=2
5*3=15
5/3=1
5%3=2

import java.util.Scanner;
public class Test20010{
public static void main(String args[]){
int num1,num2;
Scanner in=new Scanner(System.in);
num1=in.nextInt();
num2=in.nextInt();
/*------------------------*/
}
}

Answer 1

import java.util.Scanner;

public class Test20010 {
public static void main(String args[]) {
int num1, num2;
Scanner in = new Scanner(System.in);
num1 = in.nextInt();
num2 = in.nextInt();

/** 添加 */
long sum = num1 + num2;
long sub = num1 - num2;
long mul = num1 * num2;
int div, mod;
// 除法要判断除数是否为0
if (num2 == 0) {
div = 0;
mod = num1;
} else {
div = num1 / num2;
mod = num1 % num2;
}

System.out.println(num1 + "+" + num2 + "=" + sum);
System.out.println(num1 + "-" + num2 + "=" + sub);
System.out.println(num1 + "*" + num2 + "=" + mul);
System.out.println(num1 + "/" + num2 + "=" + div);
System.out.println(num1 + "%" + num2 + "=" + mod);
}
}

Answer 2

我也刚学，随便写了一个，你凑合用，你要的功能都实现了
import java.util.Scanner;

public class Col {
public static void main(String[] args) {
Scanner sc = new Scanner(System.in);
System.out.println("请输入第一个整数，以回车结束");
int num1 = sc.nextInt();
System.out.println("请输入第二个整数，以回车结束");
int num2 = sc.nextInt();
System.out.println("num1="+num1+","+"num2="+num2);
System.out.println(""+num1+"+"+num2+"="+(num1+num2));
System.out.println(""+num1+"-"+num2+"="+(num1-num2));
System.out.println(""+num1+"*"+num2+"="+(num1*num2));
System.out.println(""+num1+"/"+num2+"="+(num1/num2));
System.out.println(""+num1+"%"+num2+"="+(num1%num2));
}
}

Answer 3

import java.util.Scanner;

public class Test20010{
public static void main(String args[]){
int num1,num2;
Scanner in=new Scanner(System.in);
num1=in.nextInt();
num2=in.nextInt();
/*------------------------*/
int sum = num1 + num2;
int sub = num1 - num2;
long mul = num1 * num2;
int div = num1 / num2;
int mod = num1 % num2;

System.out.println(num1 + " + " + num2 + " = " + sum);
System.out.println(num1 + " - " + num2 + " = " + sub);
System.out.println(num1 + " * " + num2 + " = " + mul);
System.out.println(num1 + " / " + num2 + " = " + div);
System.out.println(num1 + " % " + num2 + " = " + mod);
//Add ended
}
}
