Thread: problem copying array elements

I have to make an array of 10 numbers then copy that array into a new array without the duplicates. I got it to the point where it will weed out dups but for some reason after I determine that a number is not already in the new array it wont let me put it in there. This is what I have so far.Thanks.

import java.util.*;
import java.io.*;
public class PrintingDistinctNumbers
{
   public static void main(String[] args)
   {
      int[] array=new int[10];
		int[] array2=new int[10];
      int num1;
      int count = 0;
      boolean results;
   //let the user input 10 numbers
      for(int i=0;i<array.length;i++)
      {
         Scanner input=new Scanner(System.in);
         System.out.println("please enter 10 numbers");
         num1=input.nextInt();
         array[i]=num1;
         }
 
         for (int j=0;j<array.length;j++)
         {
		    results=search(array2 ,array[j],count);
		   if(results=false);
		   {		   
         array[j]=array2[count];
         count++;
         break;
		}
 
      }
// just a test to make sure the numbers copied over to the new array      
System.out.println(array2[0]);
      }
 
 
 
 
//search the second array to see if the int is allready in it 
  public static boolean search(int[] array2,int value,int count2)
 {
 //create variables
 boolean found;
 //set the variables
 found= false;
 //search the array
 for(int index=0;index<count2;index++)
 {
 	if(array2[index]==value)
	{
	found=true;
	break;
	}
	}
	return found; 
 
 
   }
 
}

sorry didn't know how to do that but so far I've figured out that the issue was the breaks in the if statements ending the for loops cause my count to not count and that I had

array[j]=array[count];

backwards. But I do have another question if you don't mind helping I changed the code to this and everything works out better because I was suppose to have 2 separate methods one the copy the array element and one to search the array to see if it needs to be copied. But now since my count is in my SaveDistinctNumbers method when I try to print out the elements that were added to array2 in my main method I don't have the count which I need to tell array2 how many elements to print since I don't want to print the elements that weren't changed from the default 0. is there a way I could return array2 and count both from the SaveDistinctNumbers method?

import java.util.*;
   import java.io.*;
   public class PrintingDistinctNumbers
   {
      public static void main(String[] args)
      {
         int[] array=new int[10];
         int[] array2=new int[10];
         int num1;
 
 
 
      //let the user input 10 numbers
         for(int i=0;i<array.length;i++)
         {
            Scanner input=new Scanner(System.in);
            System.out.println("please enter 10 numbers");
            num1=input.nextInt();
            array[i]=num1;
            SaveDistinctNumbers(array[i],array,array2,count);
         }
 
         System.out.println(count);
 
      }
 
      public static int[] SaveDistinctNumbers(int num2,int[] array,int[] array2,int count)
      {
         boolean results;
 
         for (int j=0;j<array.length;j++)
         {
            int count=0;
            results=search(array2 ,array[j],count);
            if(!results)
            {		   
               array2[count]=array[j];
               count++;
 
 
 
          }
 
 
          } 
 
 
 
         return array2;
 
 
 
 
      }
 
   	//search the second array to see if the int is allready in it 
      public static boolean search(int[] array2,int value,int count2)
      {
      //create variables
         boolean found;
      //set the variables
         found= false;
      //search the array
         for(int index=0;index<count2;index++)
         {
            if(array2[index]==value)
            {
               found=true;
 
            }
         }
         return found; 
 
 
      }
 
 
 
   }

im trying to create a for loop in the main method after all the elements have been saved that looks like this but im not getting any output because in the main method count is still equal to 0.

for(int i=0;i<count;i++)
{
System.out.println(array2[i]);
}

I have count declared at 0 at the top of my main method I must have missed that when I was copying it. All Im trying to be able to do is print out array2 up until the element where nothing else was added which i would think shouldn't that hard but for some reason I just cant get it.

that's what count does so in my method to save the numbers count is set to 0 . the user enters a number and that is saved into array 1 wether it is a number the user already entered or not then i call the method to SaveDistinctNumber which calls my search method and if the search method finds that the number has already been entered the number isn't added to the second array , but if the number hasn't been entered yet it returns false which causes SaveDistintNumber to add the number to the new array and increment count by 1.

because it is set to 0 inside the SaveDistinctNumber method doesn't increment until it is inside the for loop in the SaveDistinctNumber method that's why i was talking about returning count to the main method but when I return it it goes into the for loop that calls that method which is a separate loop then the loop that needs to controlled by the count
