I've checked everything but still duplicate the last array for some reason.
What seems to be the problem?
In the Program, the first thing is to ask a user to input array size, then input numbers to that size.
Next, the code shall remove the duplicate number that a user inputted.
Lastly, the output will display the elements of the array without any duplicate.

Below is the program/code for the same:-

 import java.util.Scanner;

 public class Finals
 
 private static Scanner sc;

 public static void main(String args)
 

 int tao, hayop, counter, bilang = 1, result, taonghayop;

 sc = new Scanner(System.in);

 System.out.print("Enter array size: ");

 int userInput = sc.nextInt();
 int userInput1 = userInput;
 int userDatabase = new int[userInput];

 for(counter=0;counter<userInput;++counter)
 
 System.out.print("Enter array elements of index " +bilang +": ");
 userDatabase[counter] = sc.nextInt();
 bilang++;
 

 for(tao=0;tao<userInput;++tao)
 
 for(hayop=tao+1;hayop<userInput;)
 

 if(userDatabase[tao] == userDatabase[hayop])
 
 for(taonghayop = hayop; taonghayop<userInput;taonghayop++)
 
 userDatabase[taonghayop] = userDatabase[taonghayop+1];
 
 userInput = userInput-1;
 
 else
 hayop++; 
 
 

 System.out.print("The number(s) are: " + userDatabase[counter]);

 for (result=0; result<=userInput1; result++) 
 
 if (result<userInput1) 
 
 System.out.print(" ");
 System.out.print(userDatabase[result]);
 System.out.print(",");

 
 else if(result==userInput1)
 
 System.out.print(" and ");
 System.out.print(userDatabase[result]);
 System.out.print(".");
 break;
