Android (method for checking an arrays for repeated numbers?)

I’ve just asked a question and got a few answers and i was very happy to, but there were very complicated answers, I’m quite new to android so can some one maybe give me some example code or some think explained not the complicated. I’ve tried there code and tried to make sense of it but i cant.

here is the question….

could any one help me. i am making an app, and in the java, numbers are send to a int array and i need to check if any of the numbers in the array repeated and if there are to call a method or something like that. Is there a method to check this or something similar? or would i have to do it using loops and if statements, which i have tried but is getting a bit long and confusing. Any advice would be great, thanks.

int test[] = {0,0,0,0,0,0,0}; (The Array)

Answer 1

I would store the items in a Set if you do not want them to repeat. If add returns false then you have a repeating number

Set uniqueItems = new HashSet();
for(int i=0;i<test.length;i++)
    if(!uniqueItems.add(test[a]))
       System.out.println("The item is already in the set");
