编译并执行引用jar中类文件的主类 [英] Compiling and executing main class which refers to class files in jar

问题描述

我是Java的新手，想知道如何编译和执行引用jar中类文件的主类.

I am a newbie to java and would like to know how to compile and execute main class which refers to class files in jar.

例如.

package com.java;

public class A {
    public void a(){
        System.out.println("In A");
    }
}

package com.java;

public class B extends A {
    public void b(){
        System.out.println("In B");
    }
}

现在，我创建一个包含这两个类A和B的jar文件.

Now i create a jar file containing these 2 classes A and B.

我有一个主类，它引用了A类和B类.

I have a main class which refers classes A and B.

package other;

public class Main {
    public static void main(String[] args){
        A a = new A();
        B b = new B();
        a.a();
        b.b();
    }
}

我如何编译和运行Main class?

How do i compile and run Main class?

谢谢

推荐答案

您可以

java -classpath yourJarFile.jar other.Main 

您还可以在jar的清单文件中指定它(文档).

You can also specify it in manifest file in jar (documentation).
