Variables can be: static instance or local and based on their type, they can be: primitive or reference So a variable can be local and reference at the same time. Local variable is defined inside a method, block or inside for statement. Variables of a reference type hold a reference to some object. Example: class Program { public static void main (String [] args) { Program p; } } Here p is a reference and a local variable.
