Question

Suppose you have an arraylist of 10 indexes including either the numbers 1, 2, or 3 only. I am trying to get these to print without repeating the same number consecutively if possible.

For example, arraylist includes the numbers {1,1,1,2,1,2,2,3,1,2}
I would like it to print as: {1,2,3,1,2,1,2,1,2,1}

Sorry if this can be done much simpler than what I am trying to do. I am still pretty new to programming.

    int j;
    int k;
    for (j=0; j<p.size()-1;j++)
    {
        for(k =1; k<p.size()-1;k++)
        {      
            if(p.get(k)==p.get(j))
            {
    //       Person temp = p.get(j);
    //       p.remove(j);
    //       p.add(temp);
            }        
        }
    }

Not just that.. Try this:

for (int i = 0; i < list.size() - 1; i++) {
    if (!list.get(i+1).equals(list.get(i)) {
        System.out.print (list.get(i));
    }
}
