What is a nested control structure?

A nested control structure refers to a control structure that contains another control structure within it. In Java programming, control structures include loops (like for and while), conditional statements (like if and switch), and others. When one of these structures is placed within the body of another, it creates a nesting effect.

For example, you might have a loop that includes an if statement inside it, allowing conditions to be checked during each iteration of the loop. This setup is often used for complex conditional logic, such as when processing multidimensional arrays or handling more detailed decision-making processes. The capability to nest control structures enables developers to create more intricate and robust logic flows in their programs, leading to better control over the execution of code based on various conditions.
