Example of default constructor that displays the default values?
In the below class,you are not creating any constructor so compiler provides you a default constructor.Here 0 and null values are provided by default constructor.
package com.mindclues; class DefaultConstructor { int id; String name; void display() { System.out.println("Default value of int (id) "+id); System.out.println("Default value of String(name) "+name); } public static void main(String args[]) { DefaultConstructor s1 = new DefaultConstructor(); DefaultConstructor s2 = new DefaultConstructor(); s1.display(); s2.display(); } }
Default value of int (id) 0 Default value of String(name) null Default value of int (id) 0 Default value of String(name) null
