Java program to get class name without package

In this example we are making a simple example which describes you that how you can get the class name without package. For this purpose we have to fetch first the full class name with package and after then we will remove the package name with string manipulation functions. As a result we will finally get the class name without package.

In this code we have first created an object of "Class" by the String class. Following code does this for us.

Class cls = java.lang.String.class; now we can get the full class name with the method getName(). It can be done as follows:

String clsname= cls.getName(); It will return string java.lang.String and from here we have to get the "String" by removing "java.lang".

int mid=clsname.lastIndexOf ('.') + 1;
String finalClsName = clsname.substring(mid);

Above lines of code gets the class name without package.Here is the example code of GetClassWithoutPackage.java as follows:

GetClassWithoutPackage.java


import java.util.*;

import java.lang.*;

import java.net.*;



public class GetClassWithoutPackage

{

  public static void main(String args[]) {

  Class cls = java.lang.String.class;

  String clsname= cls.getName();

  System.out.println("Full class name ="+clsname); 

  int mid=clsname.lastIndexOf ('.') + 1;

  String finalClsName = clsname.substring(mid);

  System.out.println(finalClsName);

  }

}

Output:

C:\javaexamples>javac GetClassWithoutPackage.java

C:\javaexamples>java GetClassWithoutPackage
Full class name =java.lang.String
String
