Removing duplicate strings from an array?

Question

How can I remove duplicate strings from a string array without using a HashSet?

I try to use loops, but the words not delete.

StringBuffer outString = ne

Try this...

public class RemoveDupsStringArray {

public static void main(String[] args) {
    String[] withDuplicates = new String[] {"one","one","two","three","one","three","three"};
    String[] withoutDuplicates = new String[] {"one","two","three"};

    removeDuplicates(withDuplicates);
    removeDuplicates(withoutDuplicates);
}

private static void removeDuplicates(String[] array) {
    int[] occurence = new int[array.length];
    for (int i = 0; i < array.length; i++) {
        for(int j=i+1;j
