do abstract methods have to be implemented exactly the same code example
Example: write a program in which an abstract class is being defined containg an abstract method omputer(int a, int b) and a non abstract method as well
abstract class Sum{
public abstract int compute(int a, int b);
public void disp(){
System.out.println("Method of class Sum");
}
}
class Demo extends Sum{
public int compute(int a, int b){
return a+b;
}
public static void main(String args[]){
Sum obj = new Demo();
System.out.println(obj.compute(3, 7));
obj.disp();
}
}
