    slider controlling height of wave

    Hi all,

    I need to use a slider to control the height of the wave, but have no idea!

    I have created a slider. Do I have to formulate another formula to control the height or is there an easier way? I may be on the wrong track :(

    Here is part of the code. Any pointers would be great!

    Code:
    private JSlider adjustHeight = new JSlider(JSlider.VERTICAL, 1, 100, 5);
  
public SineDraw()
    ...

        Thanks, random.nextInt( ) gives a printout.

        If a number is seeded,
        Random random = new Random(10)
        I find that it also does not print the given seed. Is it because it's also not called from the method? So the real seed is not 10, but someother number right?

          Random Number

          Hi,

          I am wondering if I create a random number

          Random random = new Random()

          Is there a way to print out the random number?

          I tried to System.out.prin tln("random number = " + random);

          and it printout "random number = java.util.Rando m@9304b1"

              OK, I've been thinking about this program and I can write it out and it output, but again, I can only output it continuously.
              I understand the concept that I need to count the output of prime to 10, then reset, but I am not sure how to do it. (Sorry this is my first programming class and I'm struggling :(
              Do I use for loops to do it? I tried that route, didn't work!

                How do I do that? Where should I insert the int variable?
                Sorry I am really lost on this one....

                  How to get 10 values per line in output?

                  I have been stuck on an assignment; hopefully you can help me out.
                  I have posted the code below; basically I need to output n into rows of 10 answers per line.
                  I cannot use arrays! I am able to output the answers into a continuous row, but cannot seem to break it into the requirement above.
                  [CODE=Java]class PrimeFinder {
                  public static void main(String[] args) {
                  Boolean prime;
