java - Remove duplicates from integer array

Question

I having a problem with coding this:

Write a static method named removeDuplicates that takes as input an array of integers and returns as a result a new array of integers with all duplicates removed. For example, if the input array has the elements {4, 3, 3, 4, 5, 2, 4} the resulting array should be {4, 3, 5, 2}

Here's what I have done so far

public static int[] removeDuplicates(int []s){
    int [] k = new int[s.length];
    k[0]=s[0];
    int m =1;
    for(int i=1;i<s.length;++i){
        if(s[i]!=s[i-1]){
            k[m]=s[i];
            ++m;
        }//endIF
    }//endFori
    return k;
}//endMethod

Answer 1

To Preserve the ordering and to remove duplicates in the integer array, you can try this:

public void removeDupInIntArray(int[] ints){
    Set<Integer> setString = new LinkedHashSet<Integer>();
    for(int i=0;i<ints.length;i++){
        setString.add(ints[i]);
    }
    System.out.println(setString);
}

Hope this helps.
