Same values in an array

[hawaiifiver]

Hello to all,

I am wondering how to compare values in an array to see if any two values are the same.

can i use nested for loops with this?

Thanks.

That's the beauty of programming -- you have the ability and freedom to create something, and when doing this, you can try almost anything out. If it doesn't work, no harm, no foul.

So my advice: sure give it a try, you've nothing to lose.

Good luck.

Hi all. I worked the following out. It works if there are two values. Like if i enter 2,3,3,4,5 or 5,6,7,8,6. But it wont work with 4,5,4,6,4. Any ideas?

class Array

{

	public static void main (String [] args)

	{

	int [] array = new int[5];
	int count = 0;

	System.out.println("Please enter five numbers:");

	for (int i = 0; i < array.length; i ++)

	{ array[i] = Console.readInt(); }

	System.out.println();
	System.out.println();






	for (int i = 0; i < array.length; i ++)

	{

	for (int j = 1; j < array.length; j++)
	{
	if (array[i] == array[j] && j != i)
	count++;

	}


	}

	System.out.println();



	System.out.println(count);

	}// main

}// class

its better to say:
for (int j = i+1; j < array.length; j++)

edit:
and i would zero out the matched numbers. (or make it -1 or whatever)
if (array[i] == array[j] && array[j] != 0)
count++;
array[j] = 0;
}
