关于java联接mysql创建表

关于java连接mysql创建表
问题很简单
写了一个连接数据库并创建表的程序

创建表的时候出了问题，代码如下

Java code

    String str="THIRD";                        statement.executeUpdate("CREATE TABLE"+" "+str+""+"( NAME VARCHAR(20),"                                                                  +"GROUP VARCHAR(20)"+")");

错误
com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'GROUP VARCHAR(20))' at line 1

请问大家 创建表的格式该怎么写

GROUP是关键字。换个就可以了,比如GROUP_A
