Java const Keyword
Example
Java does not use const. Use final to create a variable that cannot change:
public class Main {
public static void main(String[] args) {
final int myNum = 15;
System.out.println(myNum);
}
}Definition and Usage
The const keyword is reserved in Java, but it is not used. You cannot use it in your code, and you cannot use it as a name for a variable, method or class.
To create a constant (a variable that cannot change), use the final keyword instead, like in the example above. If you try to change myNum later, Java gives an error.
