In Java, the static keyword is a powerful feature primarily used for memory management and allows creating members that belong to a class rather than instances of the class.
Static variables and methods are shared among all instances, static blocks execute at the time of class loading, and static members can be accessed without creating objects of the class.
Static features include static variables (class variables), static methods, and static blocks for memory efficiency and consistent shared data handling.
The static keyword helps save memory, facilitates easy maintenance of shared values, and its use cases include scenarios like storing common data, utility methods, and initialization during class loading.
