How to enable HTTP Basic Authentication in Spring Security using Java and XML Config

In the last article, I have shown you how to enable Spring security in Java application and today we'll talk about how to enable Basic HTTP authentication in your Java web application using Spring Security. I'll show you how to do that using both the Java configuration and XML configuration if you are using Spring Security 3.1 or lower version, but before that let's understand what is Http basic authentication and why do you need that? One of the most common ways to authenticate a user in a web application is by using form login i.e. you provide a login page and user will enter his username and password for authentication. This works great for human users but sometimes there are situations where you can't use a login form for authentication.

10 Gift Ideas for Programmers, Software Engineers, and IT Professionals

My friend circle has a lot of programmers and non-programmers and when it comes to buying gifts for birthdays, anniversary or holidays, I receive a lot of queries from my non-programmer family and friends about what to buy for a programmer? Well, buying a gift is easy but choosing or finding a right gift for someone is really really tough. I have had this experience when it comes to buying gifts for kids.

3 Ways to convert String to Boolean in Java? Examples

You can convert a String object to Boolean object or boolean primitive by using the Boolean.valueOf() and Boolean.parseBoolean() method. The steps are similar rot converting to String to other data types e.g. String to Integer and String to Long. You can use valueOf() method to convert String to Boolean object and parseBoolean() method to convert given String to boolean primitive value. Internally, valueOf() also uses parseBoolean() for parsing String but on top of that it also provides caching e.g. it can return Boolean.TRUE and Boolean.FALSE cached value for "true" and "false" string.  In fact, the Boolean.TRUE is returned only when String is equal to true ignoring case e.g. "True", "true", "TRUE" will evaluate into boolean true, hence Boolean.TRUE will be returned. For string like "Yes", Boolean.FALSE will be returned. We'll discuss the rules of String to boolean conversion in next section.

Top 5 IntelliJ IDEA and Android Studio Courses for Java and Android Development - Best of Lot

There is no doubt that IntelliJ IDEA is THE best IDE for Java development, even though Eclipse may still be probably used by more people because it's FREE, IntelliJ IDEA is the most feature rich and complete IDE. The Android Studio, which is the official IDE for Android development in Java is also based upon IntelliJ IDEA, which further cement its place as the IDE Java developer should learn. The only thing which stops me and many other Java developers to moving from IntelliJ IDEA in the past was the lack of resources. Since Eclipse was free from the start, there are tons of resources e.g. books, courses, and tutorials are available. There are also a lot of resources to learn productivity tips e.g. keyboard shortcuts and debugging techniques, but there were not many for Intelli IDEA.
