How to run program?

• 首先你需要有一個可以執行Java的環境，可以用下列指令來檢查。

  java -version

• 程式有兩個模式，可以透過載入引數來改變。 執行指令如下
  • "電腦產生亂數"模式(不帶引數也是這個模式)：

    java -jar 1A2B.jar

    或

    java -jar 1A2B.jar rand

  • "手動輸入模式"，允許輸入答案，接著進行猜題，適合你出我猜的情境

    java -jar 1A2B.jar getnum

• First you need install Java or JDK on your computer. To check it you can use command below:

  java -version

• This program has two modes. To change it you can add argument like this:

  java -jar 1A2B.jar

  or

  java -jar 1A2B.jar rand

  to start "Computer generated random numbers" mode, computer generate random number and guess it.
  
  

  java -jar 1A2B.jar getnum

  to start "Manual input answer" mode, you can input answer number and other people to guess.
