Checking if same values

[chicago1985]

I currently have two String objects I check to find out if they are the same value:

String str1 = "red";
String str2 = "yellow";
if (str1.equals(str2)){
      System.out.println("Equal");
}
else{
      System.out.println("Not equal");
}

Now how would I check 10 objects to find out if any of them have the same value?

Please advise.

 for (int i = 0; i < 9; ++i)
	for (int j = i+1; j < 10; ++j)
		if (str [i].equals (str[j]) 
			//...

another way

import java.util.Arrays;
public class ArrayTesting
{
	public static void main(String[] args)
	{
		String[] arr1 = new String[]{"one", "two", "three"};
		String[] arr2 = new String[] {"one", "two", "three"};
		if (Arrays.equals(arr1, arr2))
		{
			System.out.println("arrays are equal");
		}
		else
		{
			System.out.println("arrays are not equal");
		}
		
	}
}

... to find out if any of them have the same value ...

Any - not all.
