We are told that an abstract method is a method that is declared without an implementation. What is an implementation, and how does this method look like exactly ?

Question

In abstract classes

Answer 1

implementation refers to the code inside a method. in other words,what it does. For example:

public int Multiply(int x, int y)
{
return x * y;
}

in the above example Multiply would be the name of the method and return x*y is the implementation.

Answer 2

An abstract method is just the firm of the method inside an interface or abstract class

public String hello() ;

Then in a normal class you can implement that class

public normal class implements "some interface class whit the firm we want to implement" {

public String hello ()

System.out.println("hello") ;
}

}
