    Default Guessing game syntax help needed

    Hi Everyone,

    I am new to java and the assignments are are fairly simple for someone more experienced. I am currently having trouble with accumulating my variables for tallying the number of guesses of each color in the place that I need them to. I am also having trouble with my random number generator. I know that it is only selecting one 1 random number then using that 1 number through all 10 iterations of the loop when I need it to generate a new number for each guess. The actual specs in the books words is contained within the jpg. Thank you for any advice.

    You are setting the value of each colorGuess to 0 every time you enter the colorTally function this is clearing your saved data. You should have one place to initialize your variables.
    Writing code is your job, helping you fix and understand it is mine.

    I have correcting the colorGuess variable. Where my real challenge lies now is that each time the program runs, my random object is only generating 1 number then giving the user 10 guesses to get it right, when it should generate a new number for each guess.

    If the color needs to change after every guess then just move the function that gives you your random color into your for loop. That would cause it to regenerate each time. Seems simple or is there something i'm missing?
