Consider the given program and answer the questions given below:

class temp
{
 int a;
 temp()
 {
 a=10;
 }
 temp(int z)
 {
 a=z;
 }
 void print()
 {
 System.out.println(a);
 }
 void main()
 {
 temp t = new temp();
 temp x = new temp(30);
 t.print();
 x.print();
}
}

(a) What concept of OOPs is depicted in the above program with two constructors?

(b) What is the output of the method main()?

If the name of the class is "Yellow", what can be the possible name for its constructors?

1. yellow
2. YELLOW

4. Yellow

The basic salary of employees is undergoing a revision. Define a class called Grade_Revision with the following specifications:

Data Members	Purpose

int bas	to store basic salary
int expn	to consider the length of service as an experience
double inc	to store increment
double nbas	to store new basic salary (basic + increment)

Member Methods	Purpose
Grade_Revision()	constructor to initialize all data members
void accept()	to input name, basic and experience
void increment()	to calculate increment based on experience as per the table given below
void display()	to print all the details of an employee

Experience	Increment
Up to 3 years	₹1,000 + 10% of basic
3 years or more and up to 5 years	₹3,000 + 12% of basic
5 years or more and up to 10 years	₹5,000 + 15% of basic
10 years or more	₹8,000 + 20% of basic

Write the main method to create an object of the class and call all the member methods.
