Write a Java program, named InputSum, which prompts the user to enter positive

integer numbers using a sentinel while loop. The program should accept integer inputs until the user enters

the value $-1($negative one is the sentinel value that stops the while loop$).$ After the user enters $-1,$ the program

should display the entered numbers followed by their sum as shown below. Notice that value $-1$ is not part of

the output. The program should ignore any other negative input and should continue to run.

Make sure the program validates each entered number before processing it as the user may enter negative

numbers $($other than the sentinel value $-1).$

Hint: to remember$/$save the entered $($good$)$ positive values, you can concatenate them into a string $($separated

by comas$)$ that you can output later on$.$

Design your program such that it allows the user to re$-$run the program with a different set of inputs in the

same run $($i$.$e$.,$ use a sentinel loop, see example on slide $48,$ chapter $5).$ This characteristic$/$behavior will be

required for future programs, so please make sure you learn how to code sentinel loops in your

programs going forward.

Document your code, organize, and space out your outputs as shown below. The following sample tests show

the input prompt and the output labels. Notice the user may enter all values on one line $($first test$)$ or one value

per line $($second test$).$ DO NOT read inputs as String type. Make sure your code displays the outputs

following the test data format
