Performing operations on sets in Java

[rebellion346]

Hey guys, I need some help with this code I have. I'm running into several issues at the moment.

1 - I don't know what bitwise operators to use for finding the difference of A and B
2 - When the Union and Symmetric Difference calculate, the outputs aren't displaying 0 (I think it has something to do with the printSet at the bottom but I'm not sure

import static java.lang.Math.*;
import java.util.Scanner;

public class Assignment_1
{
	public static void main(String args[])
	{
		// Universal Set = {0, 1, 2, 3, 4, 5, 6, 7, 8, 9}
		
		int Set_A = 0;
		int Set_B = 0;
		int Intersection_Set = 0;
		int Union_Set = 0;
		int Compliment_Set = 0;
		int Difference_Set = 0;
		int Symmetric_Difference_Set = 0;
		
		int Element_Limit = 0;
		
		int[] Set = {0,0,0,0,0,0,0,0,0,0}; 
		Scanner in = new Scanner (System.in);
			
    //Reads user input as the max number of elements in set A
    System.out.print("Enter number of elements for Set A: "); 
      Element_Limit = in.nextInt();
			
    System.out.print("Enter Set A (Separate elements with spaces): ");
			
      //Populates the Set array	 		
      for (int i = 0; i < Element_Limit; i++) 
	{
	   Set[i] = in.nextInt();
	}

      //Populates set A
      for (int i = 0; i < Element_Limit; i++) 
	{
	   Set_A |= (int)pow(2.0, (Set[i] - 1));

      for (int i = 0; i < Element_Limit; i++) 
	{
	   Set[i] = in.nextInt();
	}

	Symmetric_Difference_Set = Set_A ^ Set_B; //Computes the symmetric difference of set A and B
			
     System.out.print("Compliment of A: ");
	   printSet(Compliment_Set);
	   System.out.println();
	
     System.out.print("Union of A and B: ");

	   System.out.println();

     System.out.print("Intersection of A and B: ");

	}

	static void printSet(int set)
	{
	  int mask = 1;
	  System.out.print("{");
	  for(int i = 1; i <= 10; i++)
	   {
	      if((mask & set) == 1)
	      System.out.print(i + " ");

	      set = set >> 1;
	   }
			System.out.print("}");
	}
