本程序員今天寫第一個(gè)簡書：

A+B的求和：

import java.util.Scanner;

import javax.swing.JOptionPane;

public class Count {

public static void main(String[] args) {

int num1,num2;

Scanner input = new Scanner(System.in);

System.out.print("input num1: ");

num1=input.nextInt();

System.out.print("input num2: ");

num2=input.nextInt();

System.out.print("num1+num2="+(num1+num2));

}

}
