<?php echo "<br> --- CREATE DB --- <br>"; $servername = "127.0.0.1"; $username = "root"; $password = "password"; // Create connection $conn = new mysqli($servername, $username, $password); // Check connection if ($conn->connect_error) { die("Connection failed: " . $conn->connect_error); } echo "Connected successfully"; // Create database $sql = "CREATE DATABASE myDB"; if ($conn->query($sql) === TRUE) { echo "Database created successfully"; } else { echo "Error creating database: " . $conn->error; }
When I run the script on browser, I get this message

Hello,
Var will change dynamically. It could be one of the below in each iteration.
String var = " My name is <name="name of the person" country = "some texts" >"; String var = " My name is <name="name of the person" city = "some texts" >"; String var = " My name is <name="name of the person"country = "some texts" >"; // no space after double quotes String var = " My name is <name="name of the person"city = "some texts" >"; // no space after double quotes
How can I search and return only the following string from above variables?
name="name of the person"Thank you!

Hello,
I would like to style a call now block like the one below
Here is my HTML:
<span class="glyphicon glyphicon-earphone"></span> <a href="tel:(000)926-4444" class="phone">Call Now!</a>
It does not have to be exactly the same as the image. Something close to the image would be helpful.
Thank you!

I made some progress but not working yet. Its not reaching the block of code inside the loop
LocalDateTime timeNow = java.time.LocalDateTime.now(); System.out.println( "timeNow "+ timeNow); LocalDateTime newtime = timeNow.plusMinutes(5); System.out.println( "newtime "+ newtime); Thread.sleep(5000); while(newtime.equals(timeNow)) { Thread.sleep(5000); timeNow = java.time.LocalDateTime.now(); System.out.println( "timeNow "+ timeNow); } System.out.println( "timeNow exited at "+ timeNow); -
Hello,
I like to add 5 minutes to current system time. After adding 5 minutes to the current time, I like to have a loop which will keep checking until system time has changed to the new time.
Lets say now is 11:50:01AM
Add 5 minutes to current time. So new time would be 11:55:01AM
I like to have a loop which will keep checking if system time is 11:55:01AM. If yes, exit the loop.
I started working on it but I am not quit there yet.
LocalDateTime timeNow; while(???) { Thread.sleep(6666); timeNow = java.time.LocalDateTime.now(); }Can you help?

Thanks for your reply.
I am trying to set name from one class and be able to get name from another class.
As you can see, I have set name in @Test method from CreateAccount class
.
setName("Mike");I am trying to get the same name from GetData class. How can I do it?

Hello,

public class GetData extends Base{ public String GetMyData() { return getName(); } }Test:

Quoteget name: Mike
get name: nullI expected to get "Mike" both cases but I am getting null second time.
I could fix it by writing static but I am doing some parallel testing. How can I fix it without writing static?

Hello,
Maven dependency:
<dependency> <groupId>ch.qos.logback</groupId> <artifactId>logback-classic</artifactId> <version>1.4.0</version> </dependency>
Main method
public class HelloMain { private final static Logger log = LoggerFactory.getLogger(HelloMain.class); public static void main(String[] args) { log.info("hello"); } }When I run the program in IntelliJ, I get the error on the following line:
private final static Logger log = LoggerFactory.getLogger(HelloMain.class);Quotech/qos/logback/classic/spi/LogbackServiceProvider has been compiled by a more recent version of the Java Runtime (class file version 55.0), this version of the Java Runtime only recognizes class file versions up to 52.0
I fixed it by changing the dependency version:
<dependency> <groupId>ch.qos.logback</groupId> <artifactId>logback-classic</artifactId> <version>1.3.0</version> </dependency>
Java on my pc:
C:\Users\sa>java -version java version "1.8.0_341" Java(TM) SE Runtime Environment (build 1.8.0_341-b10) Java HotSpot(TM) 64-Bit Server VM (build 25.341-b10, mixed mode)Could you please explain me why I got the error first place? Why changing the version of logback fixed the problem? I am bit confused with java compiler, JDK, JRE, and Dependency version.
If you could include an example, it would help. I am new to Spring framework.
Thank you!

Hello,
String words = "I go to summer school. I also go to winter school"; int counter = 0; if(words.contains("go to")) { counter++; } System.out.println("counter " + counter);As you can see "go to" is repeated twice. I like the counter to return the value of 2. But it returns 1. How can I count the duplicate words?
