Compare 2 array

[hoho2san]

Hi..can anybody give coding for:

user input number of random number to generate.
then, add it to array.

the output like this:

array A = [ 1 2 2 3 4 5 6 2 2]

array B = [ 1 2 3 4 5 6 ]

*the repeat number in array A will not be display again in array B

now im still doing coding for it..

Here is a solution with an amazing number of for loops:

import java.io.*;
public class Duplicates {
    public static void main(String[] args) {
        BufferedReader inFile = null;
 
        try {
            inFile = new BufferedReader(new InputStreamReader(System.in));
            System.out.print("Enter number of numbers to be entered: ");
            int a = Integer.parseInt(inFile.readLine());
            System.out.println("Enter the numbers one by one");
            int[] array = new int[a];
            for(int i = 0; i < array.length; i++) {
                array[i] = Integer.parseInt(inFile.readLine());
            }
            int[] temp = new int[a];
            int j = 0; int count = 0;
            for(int i = 0; i < array.length; i++) {
                if(!Duplicates.in(temp, array[i])) {
                    temp[j++] = array[i];
                    count++;
                }
            }
            int[] noDup = new int[count];
            for(int i = 0; i < count; i++) {
                noDup[i] = temp[i];
            }
 
 
            System.out.print("\nOriginally entered: ");
            for(int i = 0; i < array.length; i++) {
                System.out.print(array[i] + " ");
            }
            System.out.print("\nWith duplicates removed: ");
            for(int i = 0; i < noDup.length; i++) {
                System.out.print(noDup[i] + " ");
            }
 
        }
        catch(Exception e) {
            e.printStackTrace();
        }
    }
    public static boolean in(int[] a, int x) {
        boolean isIn = false;
        for(int i = 0; i < a.length; i++) {
            if(a[i] == x) {
                return true;
            }
        }
        return isIn;
    }
 
}
