    java help

    Hi guys & gals,

    Is there a way in Java that I can convert a double type number such as 3.1111111111222 to only two decimal places? So it would be as 3.11 only?

    Another question is how to do Stop a method from running in Java Code?

    For example.. I'm doing a loop.. and a user input a 'char' type.
    If it's match.. it stop excute.. other while it keeps going.

    I know have to use input, and if and else statement.

    Which I already did.. But I need a method to stop from running..

    Please help...

    Thank you so much.

    Do you mean JavaScript or Java?

    Try using a while loop. Something like this:

    Code:
    while (char1 != char2) {
       //prompt user and get input as char2
    }
