In this post we’ll show a practical example of processing tree-like structure using streams and Java 8 flatMap.
Create Java Streams
There are many ways to create Java Streams and for each of them we’ll show examples. This flexibility is needed especially when combined with flatMap!
Java 8 Comparators with Method References
Java 8 Comparators with Method References in action. We mix Java 8 static and default methods with method references to sort objects by multiple fields using chained Comparators!
Java regex remove duplicated words
Regular Expressions are very handy for text processing. In this article we’ll show Java Regex to remove duplicated words, which is a common task.
Java regex matching IP Address
A pretty cool exercise in writing Java Regular Expressions is to write Java regex matching IP Address. In this post we’ll show IP regexp and use in IP Address validator.
Remove duplicates from List in Java
We show how to remove duplicates from List in Java. Choose implementation depending on circumstances and with expected performance.
Java 8 regex match group – named capturing groups
Java 8 regular expressions have been improved with names for capturing groups. In this post we show how to used them to improve Java code maintainability!
Java 8 remove selected item from Collection
In Java 8 remove selected item from Collection? It can be done in at least two ways both of which we are going to implement here. Let’s code!
Java random integers in range
In Java random integers in range can be produced in many ways. In this post we show how to generate random numbers using Java 8 features!
Java 8 range of numbers
How to generate in Java 8 range of numbers? This is practical problem, often met when writing tests. In this post we’ll cover fast implementation, comfortable, and flexible with Java 8 Streams!
