Shifting characters in array

[Mayur]

Alright I'm trying to shift the chars in my array to the right but my code only makes it move to the left and I have no idea how to make it go right. Please help.

import java.util.Scanner;

public class RotateArray
{
    
    // Create a scanner to read from keyboard
    Scanner scanner = new Scanner (System.in);

    /**
     * Main method to allow execution from the command line
     */    
    public static void main(String[] args)
    {
        RotateArray instance = new RotateArray();    // default constructor
        
        instance.start();
        
    }
    
    /**
     * declare the arrays, prompt the user for the amount of times to rotate, rotate
     * the arrays, and finally print them out.
     */
    public void start() 
    {
        //*******************************Part 1***********************************
        char[] arrayToRotate = {
            '#', 'G', 'N', 'U', 'A', 'H', 'O', 'V', 'B', 'I', 'P', 'W', 'C', 'J', 
            'O', 'X', 'D', 'K', 'R', 'Y', 'E', 'L', 'S', 'Z', 'F', 'M', 'T' 
        };  
        
        //prompt for the amount to rotate
        System.out.println("ROTATES TO THE LEFT, NOT TO THE RIGHT");
        System.out.println("Enter an amount by which to rotate the array");
        int amount = scanner.nextInt();
        System.out.println();
        
        System.out.println("Original array is:");
        printArray(arrayToRotate);
        
        System.out.println("For 2 points, rotated array is:");
        rotateArray(arrayToRotate, amount);
        printArray(arrayToRotate);
        System.out.println();
      
    }// end start()

    /**
     * rotates the elements in an array amount times to the right.  The last
     * element wraps around to the first element
     */
    public void rotateArray(char[] array, int amount) 
    { 
        for( int j=0; j<amount; j++) {
            char a = array[0];
            int i;
            for(i = 0; i < array.length-1; i++)
            array[i] = array[i+1];
            array[i]= a;
        }
            
        
    }//end rotateArray()
    
    
    /**
     * send this method an array and it will print it out like A B C D...
     */
    public void printArray(char[] array) {
        //loop through the array
        for(int x=0; x<array.length; x++) {
            //display each index
            System.out.print(array[x] + " ");
        }
        System.out.println();
    }
    
}

    public void rotateArray(char[] array, int amount) 
    { 
        for( int j=0; j<amount; j++) {
            char a = array[0];
            int i;
            for(i = array.length-1; i > 0; i--)
            array[i] = array[i-1];
            array[i]= a;
        }
            
        
    }//end rotateArray()

should fix it. Generally whenever you have something going one direction and you want it swapped just reverse your loops. All i did was make your inner loop start at the highest value and go down instead of starting at 0 going up

Thanks for your help. Your code worked but it didn't wrap around to the beginning but I sorted that out. Thanks again
