difference between redefining and overridding

[srilavanyaa subramanian]

hi guys can any one give me an example of an method redefining and overridiing a method.I have read that static variable can be redefiend could not be override.the example they have given seems to be override so pls explain me any one

Consider this example.

class Test11 {
 
   public static void print() {
      System.out.println("Test11");
   }
 
   public void printName() {
      System.out.println("In class Test11");
   }
 
}
 
public class Test10 extends Test11 {
 
   public static void print() {
      System.out.println("Test10");
   }
 
   public void printName() {
      System.out.println("In class Test10");
   }
 
   public static void main(String[] args) {
      Test10 test10 = new Test10();
      Test11 test11 = new Test10();
 
      test10.print();
      test11.print();
 
      test10.printName();
      test11.printName();
   }
 
}

The output is

Test10
Test11
In class Test10
In class Test10

Notice that print() is a class method, and printName() is an instance method.

When you call the method print() with a Test11 reference to a Test10 object, it calls the static method print() in Test11.

When you call the method printName() with a Test11 reference to a Test10 object, it calls the overridden printName() method in Test10.
