All you change in the loop is the total variable while input2 remains unchanged, and so every time it is tested, it remains gt0 and that's why you're stuck. Why not give it another try, this time changing input2 and still changing total as well, using input2, and see if you can't get it.

While loop is a fundamental control flow structure in programming, enabling the execution of a block of code repeatedly as long as a specified condition remains true. While loop works by repeatedly executing a block of code as long as a specified condition remains true. It evaluates the condition before each iteration, executes the code block if the condition is true, and terminates when the

Execution of While Loop in Java. Now, let's understand the execution flow of while loop with the below diagram Control enters the while loop. The condition is tested. If true, execute the body of the loop. If false, exit the loop. After executing the body, update the loop variable. Repeat from step-2 until the condition is false. Examples of

Before we look at some example codes of the while loop, let's perfectly understand the working of the while loop by looking at its flowchart Examples of While loop in Java. Now that we have established our basics, and know the working of the while loop perfectly, let us take a look at some common and simple codes that involve the while loop. 1.

We commonly use Java nested while loops when dealing with two-dimensional arrays or complex data structures that need nested iterations. Keep in mind that nesting too many while loops can lead to less efficient code. So, use them judiciously. Let us take another simple example based on the nested while loops in Java. Example 8

Java While Loop. The while loop loops through a block of code as long as a specified condition is true Syntax while condition code block to be executed In the example below, the code in the loop will run, over and over again, as long as a variable i is less than 5

3. do-while Loop. The do-while loop ensures that the code block executes at least once before checking the condition. Syntax do code to be executed while condition The below image demonstrates the flow chart of a do-while loop do while loop starts with the execution of the statement. There is no checking of any condition for the first
