In Java, a nested switch is a construct where one switch statement is nested within another. This means that there is a switch statement inside the body of another switch statement. Each switch statement consists of multiple case labels and corresponding code blocks. The inner switch statement is enclosed within the code block of one of the outer switch statement’s cases.
Nested switches can be useful when you need to make multi-level decisions based on multiple criteria. However, nested switches can also make the code harder to read and maintain, especially when they become deeply nested. In some cases, it might be better to refactor the code to use other control structures or to break down the logic into smaller, more manageable functions.
It’s important to note that while nested switches can be used, it’s generally a good practice to keep your code as simple and clear as possible. If you find that your code is becoming overly complex with nested switches, consider alternative approaches such as using polymorphism, data structures, or separate functions to improve code readability and maintainability
