String[] str = {"a","b","c","d","e"}; 或String[] sql = new String[] {};1、对String定义与赋值时使用：String[] str = {"a","b","c","d","e"};和String[] sql = new String[] {"a","b","c","d","e"};的区别是什么?2、定义就是指String[] s

String[] str = {"a","b","c","d","e"}; 或String[] sql = new String[] {};1、对String定义与赋值时使用：String[] str = {"a","b","c","d","e"};和String[] sql = new String[] {"a","b","c","d","e"};的区别是什么?2、定义就是指String[] s
String[] str = {"a","b","c","d","e"}; 或String[] sql = new String[] {};
1、对String定义与赋值时使用：
String[] str = {"a","b","c","d","e"};
和String[] sql = new String[] {"a","b","c","d","e"};的区别是什么?
2、定义就是指String[] str;
赋值和初始化是指：str = {"a","b","c","d","e"};或str = ew String[] {"a","b","c","d","e"};?

String[] str = {"a","b","c","d","e"}; 或String[] sql = new String[] {};1、对String定义与赋值时使用：String[] str = {"a","b","c","d","e"};和String[] sql = new String[] {"a","b","c","d","e"};的区别是什么?2、定义就是指String[] s
首先这两种方式都是创建了字符串数组.
但是第一种方式只创建了一个String[]数组对象str.
第二种方式创建了两个String[]数组对象sql和 new String[] {"a","b","c","d","e"},相当于我创建了 new String[] {"a","b","c","d","e"};这个对象,然后把这个对象的引用赋给sql对象.
