求助，Oracle在java中连接的一些问题

1.我装了Oracle好像是不能运行这是什么原因啊？



2
我在Oracle中输入
create table Students (
       id int primary key,
       firstName varchar(20),
       local varchar(20)
);
insert into table Students values(‘s1’,’王大明’,’天津’)这两条命令就出现如下情况： 我的表已经创建可是就是无法插入数据

3.conn = DriverManager.getConnection("jdbcracle:thinalacritas:1521:COMP", "mark_h", "drw00dy";
上行中COMP", "mark_h", "drw00dy";分别代表什么？

It does not like an Oracle problem.
1) JCreator can not find jdbc, that is the JCreator configuration problem. Tell JCreator to use classes12.zip under Oracle home direcory/jdbc/lib
2) You try to create a table whose name is already used a table, a procedure, a function ....
3) Because of 2), you can not insert data, that is no surprise.
Do thing one step at a time. If the first step is not right, do not jump to the second step.
