interface:interface contain only undefined methods
Abstract: Abstract class contain some undefined methods 0r
some defined methods or all defined methods.
Ex: Real time Example

Abstrct class Son implements Father
{
public Void studyDaily();---->But his son didnot Study
daily he does n't interet Daily

System.out.println("yes Father I go to college");
}
}
