Array constants can only be used in initializers10
String params[];
params[]={user.getName(),user.getUsername(),user.getPassword(),
user.getDeb_id()+"",
user.getDep_id()+"",
user.getDut_id()+""};
这样声明不可以么 》？？求原因

采纳的答案
不可以
String params[]; params[]={user.getName(),user.getUsername(),user.getPassword(), user.getDeb_id()+"", user.getDep_id()+"", user.getDut_id()+""}; 这样你声明的params数组没有具体的引用，不可用
如果这样String params[]={user.getName(),user.getUsername(),user.getPassword(), user.getDeb_id()+"", user.getDep_id()+"", user.getDut_id()+""}; 或 String params[]=new String[]{user.getName(),user.getUsername(),user.getPassword(), user.getDeb_id()+"", user.getDep_id()+"", user.getDut_id()+""}; 声明的同时初始化,数组的静态初始化

// 正确
String[] params = {"1","2","3"};
// 报错
String[] params;
params = {"1","2","3"};
第2种写法，编译的时候编译器不知道params 的类型，所以才报错。如果这种写法正确，看看下面的写法：
Object[] params;
params = {"1","2","3"};//这个地方有歧义，Object类型还是String类型
