The do..while() loop tests the condition at the end of the loop. Therefore the loop body executes at least once. The while() loop (without do) tests the condition before entering the loop and before each iteration of the loop. The for() loop conditional expression is optional but, when specified, is tested before entering the loop and before each iteration of the loop.
All loops available in Java (for, while, do-while) have a loop termination condition that would get executed during every iteration of the loop. Without checking the loop condition the loop cannot be terminated and hence avoiding the loop condition check during iteration is not logic and Java does not do it.
If you want to execute a statement which is in while loop at least one time you can use do- while loop. this is why because initially first statements will be executed then condition will be checked. but in case of while first condition will be check then statements will be executed
The while loop is a pre-condition loop. It tests the condition at the beginning of each loop, executes the loop if it is true, and goes back to the test after executing each iteration.
for (initialisation; condition; update) { /* ... */}
If you are using for loop for(;;); or you can also define condition and iterations but the loop has to close there itself without any statement inside it. In the similar way you can define while and do while loop without any statement.

Do statement : Here the do loop exicutes once without cheching the condition and then the condition will be checked if condition becomes true then again loop begins from do and then exictes here if you are given value is n then loop exictues n+1 times.for statement : Here the for loop will be initilized first and the condition will be checked if the condition then the pointer enters the loop else not.And after completion of the loop the pointer again moves to the for statement and the increment/Decrement will be done as you provided in loop then the condition will be checked if satisfy then it enteres loop else not

A do-while loop checks its termination condition before each iteration, including the first; a do-until checks after each iteration, so that the first iteration occurs before the first check. The C language uses the word "while" for both types of loop, using the placement of the condition to control its timing:C do-while:while (condition) { /* condition checked before first loop iteration */... loop contents}C do-until:do {... loop contents} while (condition); /* condition not checked until after first loop iteration */
The while loop is a pre-condition loop. It tests the condition at the beginning of each loop, executes the loop if it is true, and goes back to the test after executing each iteration.

A Do-While loop looks like this: do { loop body } while (condition); and a While loop looks like this: while (condition) { loop body } The main difference is that the loop body is always run once in the Do-While loop, then the condition is checked to see if the loop should keep running. In a While loop, the condition is checked first, and it will not run the loop body at all if the condition is false.
The test condition in a loop is what's used to determine when the loop should end.
The syntax for writing a loop in pseudo code typically involves using keywords like "for", "while", or "do-while" to indicate the type of loop, followed by the loop condition and the code block to be executed within the loop.
