java实现猜数字⼩游戏（Swing版）
2008年的时候，在学习Java how to program第五版的时候，写过⼀个猜数字⼩游戏，是⽤Applet写的；
现在，我要⽤Swing重写这个⼩游戏，同时，加⼊⼀些新功能，如：背景颜⾊（红⾊表⽰偏⾼，蓝⾊表⽰偏低）、弹框、字体控制、布局管理器的使⽤。

代码如下：
//Guess a number between 1 and 1000
//Java how to program, 10/e, Exercise 12.14
//by pandenghuang@163
/* (Guess-the-Number Game) Write an application that plays “guess the number” as follows:
Your application chooses the number to be guessed by selecting an integer at random in the range
1–1000. The application then displays the following in a label:
I have a number between 1 and 1000. Can you guess my number?
Please enter your first guess.
A JTextField should be used to input the guess. As each guess is input, the background color
should change to either red or blue. Red indicates that the user is getting “warmer,” and blue,
“colder.” A JLabel should display either "Too High" or "Too Low" to help the user zero in. When
the user gets the correct answer, "Correct!" should be displayed, and the JTextField used for
input should be changed to be uneditable. A JButton should be provided to allow the user to play
the game again. When the JButton is clicked, a new random number should be generated and the
input JTextField changed to be editable.
