interface basics

interface

• I hope by this time you may good at abstract method & class. If it is then really good to start to learn about interface.

Method 

• Java method have two parts,
• First one is method name and parameters(if exists)
• Second is method body.

Example 

                         public void method1(int a, int b)

                         {

                                This is body of the method;

                         }

Implemented method

• A method which has method name and method body is called implemented method.
• We can say these methods as non abstract methods.

Example 

                         public void sum(int a, int b)

                         {

                                This is body of the method;

                         }

Unimplemented method

• A method which has only method name and no method body is called unimplemented method.
• We can say these methods as abstract methods.

Example 

                         public abstract void withDraw(int money);

Thanks for your time.
