Java method parameter and argument are variables that are passed in Methods. For more detail go to Local Variable article. To know more about the access modifier CLICK HERE. There are some restrictions on the access modifier that can be applied to local variables. The scope of local variables is only inside the Method, which means local variables cannot be accessed outside that Method. When a variable is declared inside a Method it is known as Method Local Variable. Such variables will be shared by all instances of an Object. They are known as Class level variables because the values of these variables are not specific to any instance but are common to all instances of a class. Variables that are declared with a STATIC keyword inside a Class (outside any Method) are known as Class variable / Static variable. For more details go to Instance Variable Java topic. Such variables are called instance variables because their values are instance specific and values of these variables are not shared among instances. Variables that are defined without the STATIC keyword and are o utside any method declaration are object-specific and are known as Instance Variables. Instance variables are used by objects to store their states. Depending on these conditions variables in Java can be divided into four categories.

Variables in Java can be defined anywhere in the code (i nside a class, i nside a method, or as a method argument) and can have different modifiers. public final int var = 9 Variables Types in Java In this case, we assign the variable an integer value.
Now that we are done defining a variable, we can initialize the above variable by assigning a value to it.
It defines the kind of value this variable can hold (int in this case) var : Name of the variable Variable Initialization final : Non Access Modifier applied to this variable. A data type defines the kind of value this variable can hold (int, long, or String, etc.).Įxample of variable definition public final int var public : Access Modifier applied to the variable. To define a variable, we need to assign a data type for that variable. These variables are used as containers to hold values (int, long, string…) during the life cycle of an application. In Java, objects store their states in variables.
