what does String.class returns

String s=new String("sudha");

will create an object of class 'java.lang.String'. The String will contain the content "sudha" (internally as a char array). That said, it would be better if the String is created as

String s="sudha";

This would help the jvm do some optimization for you.

String.class

refers to an instance of java.lang.Class which will be created for every object (implicitly). Its a statis method that returns an object of java.lang.Class associated with the String class. From this object you can get information about the String class itself. (for example, its methods, variables etc).

example

class Test{

public static void main(String args[]) {

Class cls = String.class;

System.out.println("Name of class is "+cls.getName());

System.out.println("Methods are");

java.lang.reflect.Method meth[] = cls.getMethods();

for(int i = 0; i<meth.length; i++){

System.out.println(meth[i].getName());

}

}

}
