A novice programming question...

I am trying to learn java. I know this place is for C but i really did not find other site to get help on java. So, i am hoping on you guys.

Problem: If the value of temp is < than 300, then the program should conver that temp of temp into centigrade using convertToC function and then should ask user to enter the temp again. This should happen until the temp < 300. When temp is less greater that 300, the program should end.

In this case i am basically trying to call the main function again when the user enters the value less the three. But, I am not being able to do so.

Try using a while loop:

Code:

---

while (fahrenheit > 300) {
    // Do stuff...
}

---

Don't forget to change fahrenheit every iteration.

Put the prompt inside a loop and don't exit until you get the value you need. A do-while loop would work well.

You need to use float or double data types, not int, otherwise, you won't get the proper result for an answer.

i tired while didn't work.
Can you please write the whole main function?

looping didn't work at all. I am getting into infinite loop.

You forgot to change fahrenheit every iteration. We warned you....

that is what i am doing? i can't change fahrenheit inside the loop. the user should be able to do it.

The user should be able to do it, if you let them type something in. Since you don't, they can't. Maybe you should call nextInt again, so as to let them type something in.

thank you, I was being foolish due to time pressure. I really appreciate your help .
this is really good place to start programming.

Thank you again.
