Variable shadowing occurs when a local variable in a method or constructor has the same name as an instance variable. This can lead to bugs and confusion. Fortunately, Java's "this" keyword provides a solution. By explicitly referring to the instance variable using "this," developers can resolve variable shadowing and ensure that the correct variable is accessed. This post will cover practical examples, explain when and why to use "this," and discuss best practices for writing clean and bug-free Java code.
