Compiling and executing main class which refers to class files in jar

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.

Ex.

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");
    }
}

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

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();
    }
}

How do i compile and run Main class?

Thanks

Try following: javac -classpath Main.java

here -classpath is the path of your jar file.

You can do

java -classpath yourJarFile.jar other.Main

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