The variables defined just after the class declaration are called instance variable and the variables declared inside the method are called local variable. Consider the following code snippet. Comparison/Discussion In java it is achieved by using a keyword 'private' keyword and the process is called data hiding. Data hiding on the other hand restricts the data member access by hiding the implementation details. private void method2() {.} Here the variable at high-level scope is shadowed by the low-level scope variable. Shadowing is actually hiding overridden method implementation in derived class and call the parent call implementation using derived class object. Default Default is the first line of data hiding. Where shall the stored data be used?
