15 Example of print() and println() methods in Java

Hello guys, if you have learned Java in early 2000 then there is  good chance that you must have written your first Java code using System.out.println(). For a long time, I have no idea what that mean but I alway use it to print messages on console. When I started working in Java and preparing for Java certification then I come to know that System is a class and out is an object of PrintStream which has println() method. That was a revelation for me. I also found that Java provides a powerful set of I/O classes for handling various input and output operations. Among these, the PrintStream class stands out as a versatile tool for writing formatted text to output streams. The print(), printf() and println() methods within the PrintStream class, as well as System.out.println(), are particularly useful for printing different types of data to the console or other output destinations.

Spring Hello World Example in Java using Dependency Injection

Hello All, In this Spring framework tutorial, you will learn how to write the hello world example in the Spring framework. This should be your first tutorial to start learning the Spring framework, as it gets the ball rolling. While coding and running this example, you learn a lot about the Spring framework, Spring XSD files, necessary JAR files, and more importantly how the Spring framework works. This HelloWorld program in Spring framework is an extension of the classical Java hello world program, which you might have seen earlier. This program is written using the Dependency Injection design pattern by using the Spring Frameworks' IOC container.  Even though now you can configure Spring dependency using annotations and Java configuration, this example uses a traditional XML way to configure dependencies.

How to use jQuery Class and Id Selector to find DOM elements? Example

One of the best things about jQuery is there selectors, which gives jQuery enormous power to find and select DOM elements so easily. If you are coming from JavaScript background then you might love those classical methods to find DOM elements like getElementById() and getElementByName(). They have served very well in the old days of JavaScript coding,  but once you start using jQuery selector, which is quite similar to CSS selector, I am sure you will forget them. Searching and finding HTML elements using jQuery selectors are natural, intuitive, and super easy and that's why I love them.
