Question
Illustrate the concept of constructor overloading through a java program which when given an input 1 will output ‘This is the parrot’ and when given an input 2 will output ‘this is the main’ and when given an input 3 will output ‘This is the 20 years sparrow’.Input:Input 1Output :This is the parrotInput:Input 2Output :this is the mainInput:Input 3Output :This is the 20 years sparrow
Solution
Sure, here is a simple Java program that uses constructor overloading to achieve the desired output:
public class Bird {
// Default constructor
public Bird(int i) {
if(i == 1) {
System.out.println("This is the parrot");
} else if(i == 2) {
System.out.println("This is the main");
} else if(i == 3) {
System.out.println("This is the 20 years sparrow");
}
}
public static void main(String[] args) {
Bird bird1 = new Bird(1);
Bird bird2 = new Bird(2);
Bird bird3 = new Bird(3);
}
}
In this program, we have a class Bird with a constructor that takes an integer as an argument. Depending on the value of the integer, it prints different messages. In the main method, we create three instances of Bird with different input values (1, 2, 3), which results in different output messages.
