Constructor looks like a method but it is in fact not a method. It’s name is same as class name and it does not return any value. You must have seen this statement in almost all the programs I have shared above:
MyClass obj = new MyClass();
If you look at the right side of this statement, we are calling the default constructor of class myClass to create a new object (or instance).
We can also have parameters in the constructor, such constructors are known as par
ametrized constructors.
public class ConstructorExample {
int age;
String name;
//Default constructor
ConstructorExample(){
this.name=”universitymcqs.com”;
this.age=30;
}
//Parameterized constructor
ConstructorExample(String n,int a){
this.name=n;
this.age=a;
}
public static void main(String args[]){
ConstructorExample obj1 = new ConstructorExample();
ConstructorExample obj2 =
new ConstructorExample(“universitymcqs.com”, 56);
System.out.println(obj1.name+” “+obj1.age);
System.out.println(obj2.name+” “+obj2.age);
}
}
OUPUT:
universitymcqs.com 30
universitymcqs.com 56
