removing duplicates from arrays

[bugger]

I have a String array with values in it. Their are duplicates in it. I want to duplicates from the array but don't know how to do it. I understand that I can do this using for loop - but then I have to use nested for loops and I think its not a good way of doing it.

If someone knows a better way, please advice.

Thanks in advance.

Use methods.

Code:

public class RemoveDuplicates {
    static String[] strs = {
        "arrays", "java", "manipulate", "java",
        "simple", "arrays", "manipulate", "java"
    };

    public static void main(String[] args) {
        print(strs, "strs");
        int num = getNumUniqueValues();
        String[] uniqueValues = new String[num];
        for(int j = 0, k = 0; j < strs.length; j++) {
            if(!containsValue(uniqueValues, strs[j]))
                uniqueValues[k++] = strs[j];
        }
        print(uniqueValues, "uniqueValues");
    }

    private static int getNumUniqueValues() {
        String[] values = new String[strs.length];
        int count = 0;
        for(int j = 0; j < strs.length; j++) {
            if(!containsValue(values, strs[j]))
                values[count++] = strs[j];
        }
        return count;
    }

    private static boolean containsValue(String[] array, String target) {
        for(int j = 0; j < array.length; j++) {
            if(array[j] != null && array[j].equals(target))
                return true;
        }
        return false;
    }

    private static void print(String[] array, String s) {
        System.out.println(s + ":");
        for(int j = 0; j < array.length; j++) {
            System.out.print(array[j]);
            if(j < array.length-1)
                System.out.print(", ");
        }
        System.out.println();
    }
}
