In the Java programming language, the keyword static indicates that the particular member belongs to a type itself, rather than to an instance of that type. This means that only one instance of that static member is created which is shared across all instances of the class. The keyword can be applied to variables, methods, blocks and nested class. Java Static Variables: A static variable is common to all the instances (or objects) of the class because it is a class level variable. In other words you can say that only a single copy of static variable is created and shared among all the instances of the class. Memory allocation for such variables only happens once when the class is loaded in the memory. Few Important Points: - Static variables are also known as Class Variables. - Unlike non-static variables, such variables can be accessed directly in static and non-static methods.

Java static variable We can use static keyword with a class level variable. A static variable is a class variable and doesn’t belong to Object/instance of the class. Since static variables are shared across all the instances of Object, they are not thread safe. Usually, static variables are used with the final keyword for common resources or constants that can be used by all the objects. If the static variable is not private, we can access it with ClassName.variableName // static variable example private static int count; public static String str; public static final String SL_USER = "myuser";
