Write a Java Program to Call One Constructor from another
PROGRAM: Java Program to Call One Constructor from another
/*Java Program to Call One Constructor from another*/
1: Java program to call one constructor from another
class Main {
int sum;
// first constructor
Main() {
// calling the second constructor
this(5, 2);
}
// second constructor
Main(int arg1, int arg2) {
// add two value
this.sum = arg1 + arg2;
}
void display() {
System.out.println(“Sum is: ” + sum);
}
// main class
public static void main(String[] args) {
// call the first constructor
Main obj = new Main();
// call display method
obj.display();
}
}
2: Call the constructor of the superclass from the constructor of the child class
// superclass
class Languages {
// constructor of the superclass
Languages(int version1, int version2) {
if (version1 > version2) {
System.out.println(“The latest version is: ” + version1);
}
else {
System.out.println(“The latest version is: ” + version2);
}
}
}
// child class
class Main extends Languages {
// constructor of the child class
Main() {
// calling the constructor of super class
super(11, 8);
}
// main method
public static void main(String[] args) {
// call the first constructor
Main obj = new Main();
}
}
