well this is not much you have written... make some effort!
here are couple of things to think of:
1. use a Scanner Object to get user's input
2. have a method that check if an inputted number is already exists in the array.

[japanir]

do you have to get 10 different numbers? or do you have to scan 10 numbers and print only unique numbers within the array?
that is different.

as for getting the input, get the numbers within the for loop, so you will get 10 numbers.

also, digits is an array of int values, not a single int value.
so this is wrong:

digits = input.nextInt(); 

you will have to assign values to a certian cell of the array, as:
digits[0] = //...
digits[1] = //...
or better inside the loop,
digits[counter] = //...

        for (int counter = 0; counter < digits.length; counter++)
               digits[counter] = input.nextInt(); 
                total += digits[counter];

well the "Asking for numbers" should also be inserted to the for loop block.
but just a thought, why are you using swing's JOptionPane and a Scanner Object for an input?
you can do all the coding just in the console, or just in swing.
anyways, here is how the code should be updated,:

for (int counter = 0; counter < digits.length; counter++)
         JOptionPane.showInputDialog ("Please enter 10 numbers, repeats will not be accepted."); 
         {digits[counter] = input.nextInt();  
                total += digits[counter]; 
         } 

hint for the part of non duplicate numbers:
for every new inputted number, go over the already inputted numbers in the array.
if the number is not already in, add it. else, post an error messege and ask for a new input.

well the JOptionPane part should be inside the for loop:

for (int counter = 0; counter < digits.length; counter++){
         JOptionPane.showInputDialog ("Please enter 10 numbers, repeats will not be accepted.");  
         digits[counter] = input.nextInt();   
                total += digits[counter];  
         }

anyone? I still need help with this.... it is frustrating me so much lol

if you declare an array of 10 int values declare it as:
int[] digits = new int[10];
array's indexes are numbers between 0 - length - 1.
in your case 0 - 9 (which is 10 values).
declaring it as you did (int[9] will create an array of 9 int values (indexes of 0 - 8).

again, if you use swing's JoptionPane, why also get input from the console?
first decide what you prefer. Console, or JOptionPane.
in case of using the console do it as:

private void Runit() 
{ 
        int[] digits = new int[10]; // array declaration 
        int total = 0; // holds the total amount of numbers entered 
        Scanner input = new Scanner(System.in); // scanner to take users input 
         
        System.out.println ("Please enter 10 numbers, repeats will not be accepted."); 
        for (int counter = 0; counter < digits.length; counter++){ 
        System.out.println("enter a number");
        digits[counter] = input.nextInt();    
               total += digits[counter];   
        }  
         
        System.out.println(digits[1]); 
                 
}// end run it 
}// end  numbers

or else, if you prefer using JOptionPane, do it as follows:

private void Runit() 
{ 
        int[] digits = new int[10]; // array declaration 
        int total = 0; // holds the total amount of numbers entered 
        
        for (int counter = 0; counter < digits.length; counter++){ 
        digits[counter] = Integer.parseInt(JOptionPane.showInputDialog ("Please enter a number."));   
               total += digits[counter];   
        }  
         
        System.out.println(digits[1]); 

       
                 
}// end run it 
}// end  numbers

notice that when using a JOptionPane, no Scanner Object is needed. you get the input through the JOptionPane.
also note that you have to parse the returned value of the JOptionPane, as it returns a String Object, and you want int values.
make sure that when inputting numbers you input ONLY int values, or else you will get an exception.
