    Default Creating more than one consumer/producer thread based on input number

    I am try to create more than one thread of producer and consumer based on the number from the input screen. I used this and all I got was the producer 1 set 1 and no consumer. Here is the code section:
    public void Consumer(int numberofconsumers, int sleep){
    SynBuffer buffers = new SynBuffer();
    for (int i = 0; i <= numberofconsumers; i++){
    new Thread(new Consumer(buffers,i)).start();
    //This constructor creates any number of consumer threads entered into the GUI screen
    public void Producer(int numberofproducers, int sleep){
    SynBuffer buffer = new SynBuffer();
    for(int i = 0; i <= numberofproducers; i++){
    new Thread(new Producer(buffer,i)).start();

    sleep time for them is supposed to be taken in from the input as well. please help

    Default Re: Creating more than one consumer/producer thread based on input number

    You call one a constructor, but I don't think that's what you mean. Instead, they're methods that call constructors. As methods, their names should not be capitalized.

    Since the methods are essentially identical and one produces the desired result and the other doesn't, then the problem must be in either the previous logic that calls the methods (one is called, the other isn't) or in the subsequent logic that uses the results, the producer thread is being seen but the consumer isn't. Both methods produce one object even if the desired number of objects is zero. I think that is a logic error, but that's not the source of your error. It is an indication that the problem you're trying to solve is outside the method.

    Add some print statements to ensure the methods are being called and that the desired constructors are then producing the desired objects. Also ensure that you're not getting runtime errors that you're not seeing.
