Class loader

[Ranjith bala]

What are the different types classloader in Java?

??
Well the classes that ship with the jdk are
ClassLoader
SecureClassLoader
URLClassLoader
and RMIClassLoader

The bootstrap ClassLoader that is used by the JVM that Sun provides is sun.misc.Launcher$AppClassLoader which is a subclass of URLClassLoader.
But of course YOU can subclass any of these and create your OWN class loader.
Sun has a ClassLoader Tutorial that you might want to review.

Thanks cindy.
Suppose i have a class name in as String like
String str="ex".
Now i want to create the class for that name("ex"),and instant for that.I think these involves class loading .So i want to know how to load that class in the name specified as String.
Is it possible?

See the following code

 
Test.java
class Test{
public void say(){
 System.out.println("Hello");
} 
}
Test1.java
class Test1{
public static void main(String args[]){
try{
 Class c = Class.forName("Test");
 Test t = (Test)c.newInstance();
 t.say();
}
catch(Exception e)
{
 System.out.println("Excpetion is"+e);
}
}
}
 

In test1.java ,I am loading the class "Test" and
calling method say().
