Java从键盘输入多个数据

package com;
import java.io.*;
public class app3_5 {
    public static void main(String[] args)throws IOException
    {
        int num1,num2;
        String str1,str2;
        InputStreamReader in;
        in=new InputStreamReader(System.in);
        BufferedReader buf;
        buf=new BufferedReader(in);
        System.out.print("请输入第一个数：");
        str1=buf.readLine();
        num1=Integer.parseInt(str1);
        System.out.print("请输入第二个数：");
        str2=buf.readLine();
        num2=Integer.parseInt(str2);
        System.out.println(num1+"*"+num2+"="+(num1*num2));
    }
}
