Consider public class MyClass { public MyClass(){/code/} // more code… } To instantiate MyClass, you would write? MyClass mc = new MyClass(); MyClass mc = MyClass; MyClass mc = MyClass(); MyClass mc = new MyClass; public static int foo(int a, String s) { s = “Yellow”; a=a+2; return a; } public static void bar() { int a=2; String s = “Blue”; a = foo(a,s); System.out.println(“a=”+a+” s=”+s); } public static void main(String args[]) { bar(); } What is printed on execution of these methods? a = 4 s = Blue a = 5 s = Yellow a = 3 s = Yellow a =2 5 s = Blue What is true about private fields of a class? They must be used with private methods. They are accessible from anywhere inside or outside of a class. They can never be used in a class. They can be accessed only by methods inside the class they are associated with.

OOPs

In today's technology-driven world, computer programming skills are in high demand. The object-oriented programming (OOP) approach is very much useful while designing and maintaining software programs. Object-oriented programming (OOP) is a basic programming paradigm that almost every developer has used at some stage in their career. 

Constructor

The easiest way to think of a constructor in object-oriented programming (OOP) languages is:
