how to declare abstract method in java
An abstract method is the method which does’nt have any body.
Abstract method is declared with
keyword abstract and semicolon in place of method body.
public abstract void <method name>();
Ex : public abstract void getDetails();
It is the responsibility of subclass to provide implementation to
abstract method defined in abstract class
interface methods{
public void hey();
public void bye();
}
//unable to implement all the abstract methods in the interface so
// the other class automatically becomes abstract
abstract class other implements methods{
public void hey(){
System.out.println("Hey");
}
}
//able to implement all the methods so is not abstract
class scratch implements methods {
public void hey(){
System.out.println("Hey");
}
public void bye() {
System.out.println("Hey");
}
}
