java.sql.SQLSyntaxErrorException:语法错误：遇到；TABLEBOOK"；在第1行第8列

根据YouTube的教程，我正在开发一个库管理系统，但是当我尝试在derby数据库中创建表时，它会生成语法错误

我从YouTube教程中获得了这个文件，但它似乎对我不起作用。

在创建表

“创建表”+“书”

=>“创建表”之后，字符串压缩中有一个空白。您缺少一个空间…这与fx无关-首先修复db问题，然后与ui代码集成。当被困在任何地方时，请带着一个演示器回来，演示什么不符合预期欢迎来到SO！当你发布答案时，试着解释一下。答案欢迎：）准确一点：问题中的问题是一个构造错误的字符串（将硬编码部分与变量部分连接起来）-你通过硬编码全部来完全避免这个问题。。

void createConnection(){
    try{
        Class.forName("org.apache.derby.jdbc.EmbeddedDriver");
        conn=DriverManager.getConnection(BD_URL);
    }
    catch(Exception e){
        e.printStackTrace();
    }
}

void setupEmployeeTable(){
    String TABLE_NAME = "EMPLOYEE";
    
    try{
        
        stmt = conn.createStatement();
        
        DatabaseMetaData dbm = conn.getMetaData();
        ResultSet tables = dbm.getTables(null, null, TABLE_NAME.toUpperCase(), null);
        if (tables.next()){
            System.out.print("Table" + TABLE_NAME +" READY");
            
        }
