I have a doubt that about static with final

Why are we using static with final in MAX_MISSES variable ? Is only final not enough to make MAX_MISSES constant ?

static makes something a class variable, rather than to be bound to an instance.

Static means that the MAX_MISSES property is a class property. Making it static lets you handle some logic when a object from that class is created.

final indicates that the value of the variable won't change - in other words, a variable who's value can't be modified after it is declared. Use public final static String when you want to create a String that: belongs to the class (static: no instance necessary to use it), and that won't change (final), for instance when you want to define a String constant that will be available to all instances of the class, and to other objects using the class.
