Counting Loop
To increment or decrement a value
Increment or decrement the pointer by the required offset.
You may exit a nested loop in Java using a break with a label for the outer loop.

To increment or decrement a value
The three main components that control a loop are the initialization, the condition, and the increment/decrement statement. Initialization sets the starting point of the loop, the condition determines when the loop should continue running, and the increment/decrement statement updates the loop variable to progress towards the termination condition. Together, these components ensure that the loop executes the desired number of times and eventually exits when the condition is no longer met.
A for loop typically runs a specific number of times in each iteration, as determined by the loop's initialization, condition, and increment/decrement statements.
Increment and decrement only.

There is no best loop. All the loops have some special functionality which when used properly will provide great results. Here's my opinion on the three loops:for and while loop:These are entry controlled loops. In case of a for loop; initialization, condition and increment/decrement is done together inside the parenthesis. For loops are best suited for purposed where the number of iterations are fixed. In case of a while loop; initialization, condition and increment/decrement are done separately. These are best suited for purposed where the number of iterations are unknown.do-while loop:This is an exit controlled loop. Hence it is best suited for purposed where you want a set of statements to be executed despite the loop condition being false.
The nested loop.
The process of decreasing in number, size, quantity, or extent.Decrease, loss, decrement, reduction, diminution, decline, decay, etc. Decrement.
