Object[ ]params=new Object[ ]{ };详细解释!
这是 Object类型的的数组定义构建初始化一体的写法
但是里面没有初始化任何Object对象 params的index一个也没有
这写法跟 Object[] params = null;的唯一区别就是 前者非null 后者params是null
其实没什么意义,只有1个数组引用,连Object类型的引用都没有定义出来
正常的写法是
Object[] params;//定义
params = new Object[3];//构建,这时只有定义的4个引用,没有实际对象
params[0] = new Object();//初始化
params[1] = new Object();
params[2] = new Object();
后者一体的
Object[] params = new Object[]{ new Object(),new Object(),new Object()};
