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

Answer 1

You can use HashSet that does not allow dulplicate elements

public static void deleteDups(int a []) {

    HashSet numbers = new HashSet();

        for(int n : a)
        {
            numbers.add(n);
        }

        for(int k : numbers)
        {
            System.out.println(k);
        }
        System.out.println(numbers);
    }       

public static void main(String[] args) {
    int a[]={2,3,3,4,4,5,6};
            RemoveDuplicate.deleteDups(a);

}

}
o/p is 2
3
4
5
6

[2, 3, 4, 5, 6]
