Super Keyword in Java With Example
The super watchword alludes to the objects of prompt parent class. Prior to learning super catchphrase you should have the information on legacy in Java so you can comprehend the models given in this guide.
The Use of Super Keyword:
1) To get to the information individuals from parent class when both parent and youngster class have part with same name
2) To expressly consider the no-arg and defined constructor of parent class
3) To get to the technique for parent class when youngster class has superseded that strategy.
Presently lets examine them in detail with the assistance of models:
1) How to utilize super catchphrase to get to the factors of parent class
At the point when you have a variable in kid class which is as of now present in the parent class then to get to the variable of parent class, you need to utilize the super catchphrase.
Lets take a guide to get this: In the accompanying system, we have an information part num pronounced in the kid class, the part with a similar name is as of now present in the parent class. Its absolutely impossible you can get to the num variable of parent class without utilizing super catchphrase. .
/Parent class or Superclass or base class
class Superclass
{
int num = 100;
}
/Child class or subclass or inferred class
class Subclass expands Superclass
{
/* a similar variable num is pronounced in the Subclass
* which is now present in the Superclass
*/
int num = 110;
void printNumber(){
System.out.println(num);
}
public static void main(String args[]){
Subclass obj= new Subclass();
obj.printNumber();
}
}
Yield:
110
Getting to the num variable of parent class:
By calling a variable like this, we can get to the variable of parent class if both the classes (parent and kid) have same variable.
super.variable_name
How about we take the very model that we have seen over, this time on paper explanation we are passing super.num rather than num.
class Superclass
{
int num = 100;
}
class Subclass broadens Superclass
{
int num = 110;
void printNumber(){
/* Note that as opposed to composing num we are
* composing super.num in the print explanation
* this alludes to the num variable of Superclass
*/
System.out.println(super.num);
}
public static void main(String args[]){
Subclass obj= new Subclass();
obj.printNumber();
}
}
Yield:
100
As you can see by utilizing super.num we got to the num variable of parent class.
2) Use of super catchphrase to conjure constructor of parent class
At the point when we make the object of sub class, the new catchphrase conjures the constructor of kid class, which certainly summons the constructor of parent class. So the request to execution when we make the object of kid class is: parent class constructor is executed first and afterward the kid class constructor is executed. It happens on the grounds that compiler itself adds super()(this conjures the no-arg constructor of parent class) as the primary assertion in the constructor of youngster class.
How about we see a guide to comprehend what I have clarified previously:
class Parentclass
{
Parentclass(){
System.out.println("Constructor of parent class");
}
}
class Subclass expands Parentclass
{
Subclass(){
/* Compile certainly adds super() here as the
* first proclamation of this constructor.
*/
System.out.println("Constructor of kid class");
}
Subclass(int num){
/* Even however it is a defined constructor.
* The compiler actually adds the no-arg super() here
*/
System.out.println("arg constructor of youngster class");
}
void display(){
System.out.println("Hello!");
}
public static void main(String args[]){
/* Creating object utilizing default constructor. This
* will summon kid class constructor, which will
* conjure parent class constructor
*/
Subclass obj= new Subclass();
/Calling sub class strategy
obj.display();
/* Creating second item utilizing arg constructor
* it will conjure arg constructor of youngster class which will
* conjure no-arg constructor of parent class naturally
*/
Subclass obj2= new Subclass(10);
obj2.display();
}
}
Yield:

Hi!

Hi!
Defined super() call to conjure defined constructor of parent class
We can call super() expressly in the constructor of youngster class, however it would not bode well since it would be excess. It resembles unequivocally accomplishing something which would be certainly done something else.
Anyway when we have a constructor in parent class that takes contentions then we can utilize defined super, as super(100); to conjure defined constructor of parent class from the constructor of kid class.
We should see a guide to get this:
class Parentclass
{
/no-arg constructor
Parentclass(){
System.out.println("no-arg constructor of parent class");
}
/arg or defined constructor
Parentclass(String str){
System.out.println("parameterized constructor of parent class");
}
}
class Subclass expands Parentclass
{
Subclass(){
/* super() should be added to the main assertion of constructor
* else you will get an aggregation blunder. Another significant
* highlight note is that when we expressly utilize very in constructor
* the compiler doesn't conjure the parent constructor naturally.
*/
super("Hahaha");
System.out.println("Constructor of kid class");
}
void display(){
System.out.println("Hello");
}
public static void main(String args[]){
Subclass obj= new Subclass();
obj.display();
}
}

Constructor of youngster class
Hi
There are not many significant focuses to note in this model:
1) super()(or defined very should be the primary assertion in constructor else you will get the accumulation mistake: "Constructor call should be the principal articulation in a constructor"
2) When we expressly positioned very in the constructor, the java compiler didn't consider the default no-arg constructor of parent class.
3) How to utilize super watchword if there should be an occurrence of strategy abrogating
At the point when a kid class proclaims an equivalent technique which is as of now present in the parent class then this is called strategy abrogating. We will learn technique abrogating in the following instructional exercises of this arrangement. For the time being you simply need to recollect this: When a kid class supersedes a strategy for parent class, at that point the call to the technique from kid class object consistently call the youngster class variant of the technique. Anyway by utilizing super catchphrase like this: super.method_name you can call the technique for parent class (the strategy which is superseded). If there should arise an occurrence of technique abrogating, these phrasings are utilized: Overridden strategy: The strategy for parent class Overriding technique: The technique for youngster class Lets take a guide to comprehend this idea:
class Parentclass
{
/Overridden strategy
void display(){
System.out.println("Parent class strategy");
}
}
class Subclass expands Parentclass
{
/Overriding strategy
void display(){
System.out.println("Child class strategy");
}
void printMsg(){
/This would call Overriding strategy
show();

super.display();

Subclass obj= new Subclass();
obj.printMsg();

}
Yield:

Consider the possibility that the youngster class isn't abrogating any technique: No need of super
At the point when kid class doesn't supersede the parent class technique then we don't have to utilize the super catchphrase to call the parent class strategy. This is on the grounds that for this situation we have just a single adaptation of every strategy and youngster class approaches the parent class techniques so we can straightforwardly call the strategies for parent class without utilizing super.
class Parentclass
{
void display(){
System.out.println("Parent class strategy");
}
}
class Subclass expands Parentclass
