小弟是初学者，有个问题请教
写的javabean程序
package bookshop;
import java.sql.*;
import bookshop.*;
public class DBSQLManager {
protected Connection conn = null; //Connection 对象
protected Statement stmt = null; //Statement 对象
protected ResultSet rs = null; //ResultSet 对象
protected String sqlStr; //SQL语句
public DBSQLManager(){
try
{
sqlStr = " ";
DBConnectionManager dcm = new DBConnectionManager();
conn = dcm.getConnection();
stmt = conn.createStatement();
}
catch (Exception e){
System.out.println(e);
IsConnect = false;
}
}
public Statement getStmt() {
return stmt;
}
public Connection getConn(){
return conn;
}
public ResultSet getRs(){
return rs;
}
public void setSqlStr(String newSqlStr){
this.sqlStr = newSqlStr;
}
public String getSqlStr(){
return sqlStr;
}
public void executeQuery() throws Exception {
rs = stmt.executeQuery(sqlStr);
}
public void executeUpdate() throws SQLException{
if (stmt != null){
stmt.close();
stmt = null;
}
conn.close();
conn = null;
}
}
错误是：isConnect cannot be resolved
这是怎么回事？
[解决办法]
你都没声明，当然cannot be resolved了
[解决办法]
贊同！
[解决办法]
在前面声明一下：
private boolean IsConnect=false;
[解决办法]
声明下应该没问题;
