below java file code:-

    package util;     import java.sql.connection;     import java.sql.drivermanager;     import java.sql.preparedstatement;     import java.sql.resultset;      public class javasqlconnection{          public static void main(string[] args) throws exception {             string connectionurl="jdbc:sqlserver://10.6.1.67";             string port="1433";             string databasename="microsoft";             string user="selenium";             string password="password123";             class.forname("com.microsoft.sqlserver.jdbc.sqlserverdriver").newinstance();             connection conn = drivermanager.getconnection(connectionurl+":"+port+";databasename="+databasename+";user="+user+";password="+password);              string sql = "select name, address, url school schoolid=?";             preparedstatement stmt = conn.preparestatement(sql);             resultset rs = null;             stmt.setint(1, 875632);             rs = stmt.executequery();             while (rs.next()){                 system.out.println(rs.getstring("url"));             }             stmt.close();             conn.close();         }     }
