    Default For loop in array

    Hello,

    I have a question about a program i have to write.
    I have to build an hopsital. This hospital has an array of rooms. Each room contains an array of patients.
    The length of the patientarray is random, so I don't know how many patients i can put in an room.
    I have to know in which room there is room for an patient. Therefore i have to create an for loop. This for loop has to return in where there is an place available for the patient. I really don't know how to do that. Can anybody help me?
    I'm working with BlueJ.

    By the way, sorry for my bad English. Im from Holland.

    This is the sourcecode i have written yet. (kamer=room in dutch)

    public Kamer()
    {
    Random generator = new Random();
    int randomIndex = generator.nextInt(5);
    int kamers [] = new int [randomIndex];
    kamertjes = kamers;
    }

    public int getKamer()
    {
    return kamertjes.length;
    }

    Hello Mickeydus,

    Do you know how to loop through an array and just display the value at each index? If so, then it is just a matter testing the value with a simple if statement to see if that position is vacant.
