In this tutorial, we will learn What is null in Java? there is nothing special type of value that we call null but if we do not specify the value or we can say if we do not enter any value in a variable then by default a value is entered in the variable that we call null and we can always edit it and enter any data in that later.
Null Values
Null value refers to there is nothing in variable pr Object to understand better let’s take an example.
Suppose we have created a variable and trill now you have not entered any value in it. But the variable is created, that time if we say what is stored in it and we try not to print it will result in null which means till now Null is tried in and when we print null will be printed.
Although we if ask literally what is stored in that variable we would say there is nothing but there is null as we have to print something as we are printing so to print something we just print null which same as nothing for Machine it is just nothing.
In another way, it is nothing for computers. let’s understand it in a better way using an example.
class Main {
public static void main(String[] args) {
int a = 5,x;
System.out.println(x);
}
}
The above code will result as null as the value of x is not initialized so it has nothing which is null in the case of programming languages.
