Binary Search vs Contains Performance in Java List - Example

There are two ways to search an element in a List class, by using contains() method or by using Collections.binarySearch() method. There are two versions of binarySearch() method, one which takes a List and Comparator and other which takes a List and Comparable. This method searches the specified list for the specified object using the binary search algorithm. The list must be sorted into ascending order according to the natural ordering of its elements (as by the sort(List) method) prior to making this call. If List is not sorted, then results are undefined. If the List contains multiple elements equal to the specified object, there is no guarantee which one will be returned. This method runs in log(n) time for a "random access" list (which provides near-constant-time positional access).

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.
