Getting started

In this tutorial, You will learn how to create a simple web application using Spring Boot and deploy it into a Tomcat Server.
In this tutorial, You will learn how to increment table field value using PHP Codeigniter. Recently I have implemented this in my blog when the article page viewed increment the view count by 1.

By default Spring Boot application accessed via root context path ("/") like http://localhost:port/. But in real world application development, you have to specify the context path http://localhost:port/{app_name}.

In this tutorial, we will learn the different ways to configure root context.

I am trying to build & run the Spring Boot application with simple RestController. After hitting the RequestMapping URL, I am getting Whitelabel Error Page with status code "404".

[ERROR] Failed to execute goal org.springframework.boot:spring-boot-maven-plugin:2.0.2.RELEASE:repackage (default) on project SpringBoot: Execution default of goal org.springframework.boot:spring-boot-maven-plugin:2.0.2.RELEASE:repackage failed: Unable to find main class

In this java tutorial, You will learn how to use String.charAt(int index) method. This method, Returns the char value at the specified index. An index ranges from 0 to length() - 1.
In this java tutorial, You will learn how to use codePointAt(int index) method of String class. This method, Returns the character (Unicode code point) at the specified index. The index refers to char values (Unicode code units) and ranges from 0 to length() - 1. If the char value specified at the given index is in the high-surrogate range, the following index is less than the length of this String, and the char value at the following index is in the low-surrogate range, then the supplementary code point corresponding to this surrogate pair is returned. Otherwise, the char value at the given index is returned.
In this java tutorial, You will learn how to use codePointBefore(int index) method of String class. This method, Returns the character (Unicode code point) before the specified index. The index refers to char values (Unicode code units) and ranges from 1 to length. If the char value at (index - 1) is in the low-surrogate range, (index - 2) is not negative, and the char value at (index - 2) is in the high-surrogate range, then the supplementary code point value of the surrogate pair is returned. If the char value at index - 1 is an unpaired low-surrogate or a high-surrogate, the surrogate value is returned.
In this java tutorial, You will learn how to use intValue() method of Short class. This method, Returns the value of this Short as an int. This method returns the numeric value represented by this object after conversion to type int.
In this java tutorial, You will learn how to use longValue() method of Short class. This method, Returns the value of this Short as a long. This method returns the numeric value represented by this object after conversion to type long.
