Difference between start and run method in Thread? Example

Why to do one call start method of the thread if start() calls run() in turn" or "What is the difference by calling start() over run() method in java thread" are two widely popular beginner level multi-threading interview question. When a Java programmer start learning Thread, the first thing he learns is to implement thread either overriding run() method of Thread class or implementing Runnable interface and then calling start() method on the thread, but with some experience, he finds that start() method calls run() method internally either by looking API documentation or just poking around, but many of us just don’t care at that time until it been asked in Java Interview.

Why use Underscore in Numbers from Java? Underscore in Numeric Literals Example

JDK 1.7 release had introduced several useful features, despite most of them being syntactic sugar, there use can greatly improve readability and code quality. One such feature is the introduction of underscores in numeric literals . From Java 7 onwards you can write a long digit e.g. 10000000000 to a more readable 1 0_000_000_000 in your Java source code. One of the most important reasons for using an underscore in numeric literal is avoiding subtle mistakes that are hard to figure out by looking at code. It's hard to notice a missing zero or extra zero between 10000000000 and 1000000000 , than 10_000_000_000 and 1_000_000_000 .

3 ways to convert String to Boolean in Java? Examples

You can convert a String object to a 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  like  String to Integer and String to Long . You can use the  valueOf() method to convert String to Boolean object and parseBoolean() method to convert a given string to a 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" strings.
