The Java do-while loop is a post-test control structure that executes a code block at least once before evaluating a Boolean condition. It contrasts with the while loop by checking the condition after execution, making it ideal for scenarios where at least one iteration is required, such as user input validation or file processing. This loop is beneficial for its guaranteed execution and reduction in code redundancy, enhancing program efficiency.

The do-while loop in Java guarantees the execution of a code block at least once, with subsequent iterations depending on a Boolean condition
Entry-Controlled vs. Exit-Controlled Loops
The do-while loop is exit-controlled, executing the code block before checking the condition, while the while loop is entry-controlled, evaluating the condition before any code execution
The do-while loop is useful for user interactions, file processing, and input validation, and offers benefits such as guaranteed initial execution and reduced code redundancy
A do-while loop can be used to count from 1 to 5, continuing to increment and print a number until the condition is no longer satisfied
In gaming, a do-while loop can prompt players to replay, and in file processing, it ensures an initial attempt to read data
The do-while loop guarantees initial execution and minimizes code redundancy, enhancing efficiency and code clarity
The do-while loop mirrors real-world scenarios where an action is taken before a decision on its repetition is made
