A final variable is a variable which has been initialized to a fixed value which cannot be changed after initialization. Once created, its value cannot be changed.
public class FinalVariable{
public static void main(String[] args) {
final int hoursInDay=24;
//IF you will try to change the value by the following statement, you will get error bcoz final value can't be changed.
//hoursInDay=12;
System.out.println("Hours in 5 days = " + hoursInDay * 5);
}
}
