我正在尝试编写一个从用户（通过键盘）读取整数的程序，向其添加100并显示结果。我所能做的就是让它们像2个字符串一样连接，而不是将数字加在一起。我无法理解为什么它不会添加它们。

I'm trying to write a program that reads an integer from the user (through the keyboard), adds 100 to it and displays the result. All I can do is get them to concatenate like 2 strings, instead of adding the numbers together. I can't understand why it won't add them.

import java.io.*; public class Program { public static void main(String[] args) throws IOException { InputStreamReader isr = new InputStreamReader(System.in); BufferedReader br = new BufferedReader(isr); System.out.print("Enter some text: "); String text = br.readLine(); int number = Integer.parseInt(text); System.out.println(" Your value + 100 is " + ( 100 + text)); } }

是我正在使用的代码，并且：

is the code I am using and:

Enter some text: 66 Your value + 100 is 10066

是在屏幕上打印的内容。

is what is printed on the screen.

推荐答案

你是添加错误的变量。改为使用：

You are adding the wrong variable. Use this instead:

System.out.println(" Your value + 100 is " + ( 100 + number));
