• If you need a variable with a value that is accessible everywhere, then define a public class variable by instantiating the following pattern:

  public static data type variable name; 
  

• If you want to access the value of a public class variable, then instantiate one of the following patterns:

  ... class name.variable name ... 
  class name.variable name = new-value expression; 
  

• If you want a variable to be a constant, then add the keyword final to the variable declaration, and be sure to initialize the variable in the declaration statement.

  public static final data type variable name  
   = new-value expression;
