获取两个数组相同元素，不同元素，及相同元素不同元素新数组

废话不多说直接上代码！

		/**
		 * 获取两个数组相同元素
		 * @param a
		 * @param b
		 * @return
		 */
		public static <T> Set<T> getIds(T[] a, T[] b){  
			  Set<T> same = new HashSet<T>();  //用来存放两个数组中相同的元素  
		      Set<T> temp = new HashSet<T>();  //用来存放数组a中的元素  
	
		      for (int i = 0; i < a.length; i++) {  
		          temp.add(a[i]);   //把数组a中的元素放到Set中，可以去除重复的元素  
		      }  
	
		      for (int j = 0; j < b.length; j++) {  
		        //把数组b中的元素添加到temp中  
		        //如果temp中已存在相同的元素，则temp.add（b[j]）返回false  
		        if(!temp.add(b[j]))  
		            same.add(b[j]);  
		    }  
		    return same;   
		  }  
		
		/**
		 * 获取两个数组中不相同元素
		 * @param t1
		 * @param t2
		 * @return
		 */
		public static <T> List<T> compare(T[] t1, T[] t2) {    
	      List<T> list1 = Arrays.asList(t1); //将t1数组转成list数组   
	      List<T> list2 = new ArrayList<T>();//用来存放2个数组中不相同的元素    
	      for (T t : t2) {    
	          if (!list1.contains(t)) {    
	              list2.add(t);    
	          }    
	      }    
	      return list2;    
	  }
