Java Do-While Loop

In Java, the do-while loop is similar to the while loop, but it always executes the block of code at least once, even if the condition is false initially. Here's a concise overview:

Syntax:

do {
    // Code to execute
} while (condition);

Code Execution:

• The block of code is executed once before checking the condition.
• If the condition is true, the block is executed again, and the process repeats.
• If the condition is false after the first execution, the loop terminates.

Do-While Loop Example:

• Executes the block of code at least once, regardless of the condition.
• Example:

do {
    // Code to execute
} while (condition);

Use Cases:

• Useful when you want to ensure that the code inside the loop runs at least once, regardless of the condition.
• Commonly used for menu-driven programs or input validation.

Summary

The do-while loop provides a way to execute a block of code at least once and then continue executing it based on a specified condition. Understanding how to use do-while loops is essential for handling situations where the code needs to be executed at least once before checking the condition.
