java make constant code example

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.

Example 2: create constant class in java

public final class MyValues {
  public static final String VALUE1 = "foo";
  public static final String VALUE2 = "bar";
}
