In this section, you will learn about Java variables. A variable refers to the memory location that holds values like: numbers, texts etc. in the computer memory. A variable is a name of location where the data is stored when a program executes.

The Java contains the following types of variables:

Instance Variables (Non-static fields): In object oriented programming, objects store their individual states in the "non-static fields" that is declared without the static keyword. Each object of the class has its own set of values for these non-static variables so we can say that these are related to objects (instances of the class).Hence these variables are also known as instance variables. These variables take default values if not initialized.
