Current value of revNum is 32 and it is changed to 321 as shown in the output:Īt this point, we have successfully reversed the number.Īfter third iteration, number becomes zero, so the while loop completes. School and College Computer Subjects- online and offline mode. In the third iteration, the digit 1 is extracted. If you new to java and want to learn java before trying out these program, then read my Core Java Tutorials. Notice that by the end of second iteration, we have reversed 2 digits of the number. revNum is 3, multiplying it with 10 and adding 2 to it gives us 32 as shown in the output of the second iteration: I’ve never done Java before and most all I’ve been accomplishing so far is declaring variables and banging my head against the keyboard. In the second iteration, the digit 2 is extracted. Does anyone know where I can find a good (read: complete, through, easy-to-understand) tutorial for BlueJ I’ve got a class that uses it but I’m sorry to say that I’m doing very poorly in it.

Current value of revNum is zero, so the line revNum = revNum * 10 + digit multiplies 0 with 10 and adds the value of variable digit to it effectively storing digit in revNum. As you can see in the output above, in the first iteration, the digit in the unit’s place which is 3 is extracted.
