Interface in Java

This Simple Java Program is for performing Interfaces in Java. This is a part of Mumbai University MCA Colleges Java Practicals.

Interface just carry the signature of the function to be used. The class which implements a interface has to define the function which its gonna implement.

.

interface Exam

{

boolean pass(int marks);

}

interface Classify

{

String division(int avg);

}

class Result implements Exam,Classify

{

public boolean pass(int marks)

{

System.out.println("Marks obtained are "+ marks);

if(marks>=50)

return true;

else

return false;

}

public String division(int avg)

{

if(avg>=60)

return("First Division");

else if(avg>50)

return("Second Division");

else

return("Third Division");

}

public static void main(String ar[])

{

Result r =new Result();

boolean flg;

flg=r.pass(60);

if(flg==true)

System.out.println("Marks>=50");

else

System.out.println("Marks<50");

System.out.println(r.division(60)); 

}

}
