The program given below tests your understanding of inheritance and, function overloading and function overriding in Java.Given below the sample code :
class SuperClass1
{
private void m1()
{
System.out.println("SuperClass's m1()");
}
public void m2()
{
System.out.println("SuperClass's m2()");
m1();
}
}
class Modify extends Superclass
{
public void m1()
{
System.out.println("Modify's method1()");
}
public static void main(String args[])
{
SuperClass1 s = new Modify();
s.m2();
}
}
What will be the output of the following :
1. Prints : SuperClass's m1()
