Java static keyword in java can be used to declare a variable, used to make a method static, and also to declare a static block. When static keyword is used, it means we can use the variable, method etc without creating instance of the class. We can use class name dot variable or method name to directly access it. Static variables are shared across all instances of that class and should be used when the variable state needs to be shared. Static block is executed when the class is loaded initially and should be used to initialize static variables. A static method can be called directly on the class and mostly used as a utility method which can be used even before the java objects are created. In rare cases, innner static classes can be created as well so keep the code more organized.
