1. Answer: In Java, static keyword is mainly used for memory management. It can be used with variables, methods, blocks and nested classes. It is a keyword which is used to share the same variable or method of a given class. Basically, static is used for a constant variable or a method that is same for every instance of a class. A member variable of a class that is declared as static is called the Static Variable. It is also called as the “Class variable”. Once the variable is declared as static, memory is allocated only once and not every time when a class is instantiated. Hence you can access the static variable without a reference to an object.
2. Answer: Method overloading increases the readability of the program. Overloaded methods give programmers the flexibility to call a similar method for different types of data. Overloading is also used on constructors to create new objects given different amounts of data.
