Java工具类：一次性打印输出自定义的所有变量（再也不用一次次地使用System.out.println()输出变量）

	 * 遍历输出数组型的可变参数
	 * @param object
	 * @return
	 */
	public Boolean printArrays(Object ...object) {
		Boolean flag = false;
		for (int i=0;i<object.length;i++) {
			//判断参数是否是数组
			if(object[i].getClass().isArray()) {

				int length = Array.getLength(object[i]);
				//自定义一个object类型的数组
				Object[] Obj = new Object[length];
				//使用 Array.get方法，把数组的值存到Object数组中
				for (int j = 0; j < Obj.length; j++) {
					Obj[j] = Array.get(object[i], j);
				}
				//遍历输出数组
				System.out.println("object["+i+"]："+Arrays.deepToString(Obj));
			}else {
