Do-while input validation

I need to write an input validation while using the do-while statement. I feel like most of it is good except that it gets stuck inside the brackets of the do statement. After I enter an input, it just keeps asking me over and over for an input. Any help?

Then I have to make it s if you enter an input that is out of range, you have to keep entering an input until it is in range.

Java Code:

         do
         {
            System.out.print("Please enter the amount of spaces the letters will shift... ");
            shift = uInput.nextInt();
         }

Java Code:

public class ShiftEncoderDecoderDriver
{
   public static void main(String[] args)
   {
      int shift;
      Scanner uInput = new Scanner(System.in);
      System.out.print("Please enter the code that you wish to encode...");
      String plainText = uInput.nextLine();
      {
         do
         {
            System.out.print("Please enter the amount of spaces the letters will shift... ");
            shift = uInput.nextInt();
         }
         while(shift > 0 || shift < 25);
            {
            System.out.print("Your shift value is set at... "+shift);
            } 
         while(shift > 0 || shift > -25);
            {
            System.out.print("Your shift value is set at... "+shift);
            }
         while(shift > 25 && shift < -25) 
            {
            System.out.print("Out of range shift amount, please enter your shift amount again.");
            shift = uInput.nextInt();
            }
       }
      
      
   }
