那位高手帮我看一下这又是哪里错了啊代码如下编写的时候没有红叉可又编译不出来解决了我加分

import java.sql.*;
public class NewsFirstTitleDB1 {
public static void main(String[]arge){
Connection connection = null;
Statement statement = null;
try{
String strsql = "insert into FirstLevelTitle values(1,'医疗','管理','2009')"; //sql插入语句
try{
Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver");
}catch(ClassNotFoundException ex){
ex.printStackTrace();
System.out.println("无法找驱动类");
}
connection = DriverManager.getConnection("jdbc:microsoft:sqlserver://localhose:1433;DatabaseName=news");
statement=connection.createStatement();
statement.executeUpdate(strsql);
}catch(SQLException de){
de.printStackTrace();
System.out.println("插入失败");
}finally{
closeStatement(statement); //调用方法关闭Statement连接
closeConnection(connection);//调用方法关闭数据库连接Connection
}
}
public static void closeStatement(Statement sjt){//关闭Statement连接
try{
if(sjt!=null){
sjt.close();
sjt=null;
}
}catch(SQLException et){
et.printStackTrace();
System.out.println("Statement关闭失败");
}
}
public static void closeConnection(Connection cin){ //关闭数据库连接Connection
try{
if(cin!=null&&(!cin.isClosed())){
cin.close();
}
}catch(SQLException de){
de.printStackTrace();
System.out.println("Connection关闭失败");
}
}
}

异常代码如下
