?What is the key difference between a "for" loop and a "while" loop in Java

The main difference is in their structure and use cases. A "for" loop is used when you know the number of iterations in advance and typically consists of an initialization, a condition, and an increment/decrement statement, all in one line. A "while" loop, on the other hand, is used when you want to repeat a block of code while a condition is true. It relies solely on a condition and may require you to manage loop control variables separately.

?When should you use a "do-while" loop in Java, and how does it differ from a "while" loop

You should use a "do-while" loop when you want to ensure that the loop body is executed at least once, regardless of whether the condition is initially true or false. In a "do-while" loop, the loop body is executed before the condition is checked, which means it's guaranteed to run at least once. In contrast, a "while" loop checks the condition first and may skip the loop body if the condition is initially false.
