Package class:

Package class provides the information about a package like package name, implementation title etc.

 * @author W3spoint
 */
public class Test {
       public static void main(String args[]){
               Package package1=Package.getPackage("java.lang"); 
               System.out.println("package name = "
                                        +package1.getName()); 
               System.out.println("Specification Title = "
                           +package1.getSpecificationTitle()); 
               System.out.println("Specification Vendor = "
                           +package1.getSpecificationVendor()); 
               System.out.println("Specification Version = "
                           +package1.getSpecificationVersion());  
               System.out.println("Implementaion Title = "
                           +package1.getImplementationTitle()); 
                }
}
