Can not get java to return to top of if loop using else statement [duplicate]

This question already has an answer here:

• Loop user input until conditions met 3 answers

I cant seem to get the program to ask again for a valid input after an invalid input and then check that new input again. I know I need a combination of if and while loops but I cant seem to get the logic correct.

Heres where the problem occours:

    // Validate input is in range
    if  (amtBars < 40 && amtBars > 10)

    // Prompt for bar type
    barType = JOptionPane.showInputDialog(null, "Please input a symbol, letter, or phrase to compose each bar:", HEADING, JOptionPane.INFORMATION_MESSAGE);

    else 
    { 
        JOptionPane.showMessageDialog (null, "Value must be between 10 and 40.", HEADING, JOptionPane.INFORMATION_MESSAGE);
        inBars = JOptionPane.showInputDialog(null, "Please input a number between 10 and 40:", HEADING, JOptionPane.INFORMATION_MESSAGE);
        amtBars = Integer.parseInt(inBars);
    }

The information will be "validated" once but then once the else is reached it will not validate again and take whatever input the user keys.

How might I go about setting up the proper while loop?
