Example 1: constants in Java

//A constant is a variable whose value won't change after it's been defined.

private static final int OUR_CONSTANT = 1;

//We make our constants static and final and give them an appropriate type, 
//whether that's a Java primitive, a class, or an enum. 
//The name should be all capital letters with the words separated by underscores, 
//sometimes known as screaming snake case.
