怎樣把java 轉換成 .class 並把它執行??

1) 你需要Java SDK (e.g. J2SE v 1.4.2_13 SDK)來將".java"檔案轉換成".class"檔案。Java SDK及Java JRE (e.g. J2SE v 1.4.2_13 JRE)皆能執行".class"檔。


2) javac.exe *.java
where "javac.exe" is located under the bin directory of your SDK installation and "*.java" are the Java files for compilation.


3) Provide that there is a static "main" method in a class with the following signature.

public static void main(String[] args);

Then you can execute it with the following command.

java.exe ABC

where "ABC" is the name of the enclosing class of the main method.

There are also alternate means to execute a Java module.

please use javac the java compiler to do it.
