Constructor Overloading In Java programming
Similar to method overloading, constructor loading is the creation and usage of constructors with diffrent type of arguments. We can use this operator to refer to constructors.See the example below.
Example
class A {
public int a;
public A() {
this(-1);
}
public A(int a) {
this.a = a;
}
public String toString() {
return "[ a= " + this.a + "]";
}
}
public class Tester {
public static void main(String args[]) {
A a = new A(10);
System.out.println(a);
A a1 = new A();
System.out.println(a1);
}
}Output
[ a= 10] [ a= -1]
