The do-while loop is a type of loop in programming that is similar to the while loop, but with one key difference: the do-while loop guarantees that the block of code inside the loop is executed at least once, regardless of whether the loop condition is true or false. Here is a sample do while loop: do { // code to be executed} while (condition); The flow of a do-while loop is as follows: Execution of Code Block: The code block inside the do statement is executed. Evaluation of Condition: After the code block is executed, the loop condition is evaluated. Loop Continuation or Termination: If the condition is true, the loop will execute the code block again. If the condition is false, the loop terminates, and the program continues with the next statement after the do-while loop. int i = 6; do { System.out.println(i); i++; } while (i <= 5); This loop will print the numbers 6. The loop will execute at least once even if the initial value of i is greater than 5. The loop condition is checked after the first execution of the code block. read less
