// returns the Class object for this class

Class myClass = Class.forName("Test");

System.out.println("Class represented by myClass: "

+ myClass.toString());

// using getClassLoader() method

System.out.println("ClassLoader of myClass: "

+ myClass.getClassLoader());

}

}

输出：

Class represented by myClass: class Test

ClassLoader of myClass: sun.misc.Launcher$AppClassLoader@42a57993

示例2:

// Java program to demonstrate getClassLoader() method

public class Test {

class Arr {

}

public static void main(String[] args)

throws ClassNotFoundException

{

// returns the Class object for Arr

Class arrClass = Arr.class;

// Get the classLoader of arrClass

// using getClassLoader() method

System.out.println("ClassLoader of arrClass: "

+ arrClass.getClassLoader());

}

}

输出：

ClassLoader of arrClass: sun.misc.Launcher$AppClassLoader@42a57993
