Hi friend,

Code to help in solving the problem :

import java.sql.*;
public class CheckResultSet {
public static void main(String[] args) throws Exception {
String driver = "com.mysql.jdbc.Driver";
String url = "jdbc:mysql://localhost:3306/";;
String username = "root";
String password = "root";
String dbName= "dbName";
Class.forName(driver);
Connection conn = DriverManager.getConnection(url+dbName, username, password);
System.out.println("Connected");
Statement st = conn.createStatement();
ResultSet rs = st.executeQuery("SELECT * FROM table");
if(rs!=null)
{
System.out.println("ResultSet is not null");
}
st.close();
conn.close();
}
}
