jdk 的问题，请高手指教！

DBconn.java 如下：

package mysqltest;
import java.sql.*;
public class DBconn
{String DBDriver="org.gjt.mm.mysql.Driver";
String ConnStr="jdbc:mysql://localhost/my_test";
String MyUser="yzysy";
String MyPassword="yzysy";
Connection conn = null;
ResultSet rs = null;
public DBconn()
{try
{Class.forName(DBDriver);
}
catch(java.lang.ClassNotFoundException e)
{System.err.println("DBconn (): " + e.getMessage());
}
}
public ResultSet executeQuery(String sql)
{rs = null;
try
{conn = DriverManager.getConnection(ConnStr,MyUser,MyPassword);
Statement stmt = conn.createStatement();
rs = stmt.executeQuery(sql);
}
catch(SQLException ex)
{System.err.println("aq.executeQuery:"+ex.getMessage());
}
return rs;
}
}


编译后，提示有100个错误，如下：
E:\JSP\jdk1.4\src.zip(java/net/URI.java):2662: warning: as of release 1.4, assert is a keyword, and may not be used as an identifier

我用的是 j2sdk-1_4_2-windows-i586.exe
请高手指点一下，这是什么原因啊！急

你的这个JAVA文件是不是只读的，你的编程环境是什么。

[chenxb1980]

assert is a keyword, and may not be used as an identifier
assert是关键字，你是不是再什么地方定义了以assert命名的
属性变量什么的

[naxin]

assert is a keyword, and may not be used as an identifier

[liqiang208]

里面没有定义 assert
这个问题还是没有解决，希望高手再来看看啊 谢谢！！！！
