how to use an abstract class in java
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");
}
}
