Write a program to remove duplicates from sorted array?

Description:

Given array is already sorted, and it has duplicate elements. Write a program to remove duplicate elements and return new array without any duplicate elements. The array should contain only unique elements.

Code:

? 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 public class MyDuplicateElements {     public static int[] removeDuplicates(int[] input){                   int j = 0;         int i = 1;         //return if the array length is less than 2         if(input.length < 2){             return input;         }         while(i < input.length){             if(input[i] == input[j]){                 i++;             }else{                 input[++j] = input[i++];             }            }         int[] output = new int[j+1];         for(int k=0; k<output.length; k++){             output[k] = input[k];         }                   return output;     }           public static void main(String a[]){         int[] input1 = {2,3,6,6,8,9,10,10,10,12,12};         int[] output = removeDuplicates(input1);         for(int i:output){             System.out.print(i+" ");         }     } }

Output:

2 3 6 8 9 10 12
