2015/3/6 JAVA程式作業 更改環境變數+CMD執行JAVA

程式設計工藝大師
http://tccnchsu.blogspot.tw/2011/02/2011-java.html
1.為何why要選修這門課?(動機)
興趣
2.希忘從這門課獲得那些知識?(目標)
學好JAVA
3.我要如何修習這一門課?(態度與方法)
認真上課

更改環境變數
可讓CMD不需變更路徑就執行JAVAC

利用CMD執行JAVA

cd為移動資料夾

javac 為編譯JAVA

java 為執行

class Test

{

public static void main(String[] args)

{

System.out.println("_____*_____");

System.out.println("____***____");

System.out.println("___*****___");

System.out.println("__*******__");

System.out.println("_____*_____");

System.out.println("_____*_____");

}

}
