Is null a literal in Java?
The null in Java is a literal of the null type. It cannot be cast to a primitive type such as int. float etc. but can be cast to a reference type. Also, null does not have the value 0 necessarily.
A program that demonstrates null in Java is given as follows:
Example
public class Demo {
public static void main(String args[]) {
String str = null;
System.out.println("Value of str is: " + str);
}
}Output
Value of str is: null
Now let us understand the above program.
In the main() method, the String str is initialized as null. Then the value of str is printed. A code snippet which demonstrates this is as follows:
String str = null;
System.out.println("Value of str is: " + str);
