We have seen Java’s ways of merging or concatenating collections together. Now, we will see how can we use the Guava library to do so.Before that, make sure you have Guava dependency in your build.Concatenate using Iterables addAll method...
This method provides a quick way to control the positioning of UI elements, ensuring a consistent and visually appealing layout in JavaFX applications. To use thesetAlignment()methods, you typically need to import classes from thejavafx.scene.layoutpackage, as this package contains the layout classes...
The first method is ArrayUtil.addAll(). It takes the values of arrays and merges them into one. Since this method is commons of apache; hence in order to use this method, apache.commons.lang3 method needs to be imported first into the compiler. Example Codes: import java.util.Arrays; ...
If you are already using the Apache Commons Lang library, just use the ArrayUtils. addAll() method to concatenate two arrays into one. This method works for both primitive as well as generic type arrays. String[] arr1 = {"a", "b", "c", "d"}; String[] arr2 = {"e", "f", ...
In this article, we will show you a few ways to join a Java Array. Apache Commons Lang – ArrayUtils Java API Java 8 Stream 1. Apache Commons Lang – ArrayUtils The simplest way is add the Apache Commons Lang library, and use ArrayUtils. addAll to join arrays. This method supports both...
Tip: There are more ways to merge lists using libraries like guava or Apache commons lang, but they all useaddAll()method only. So it’s better to use this method directly. 1.2. UsingStream.flatMap() Java 8 streams provide us with one-line solutions to most of the problems and at th...
Theadd()does not return any value. voidArrayList.add(index,itemToAdd); Similarly, if we have to add multiple items to the arraylist, we can use the methodaddAll(),which takes another collection and add it the specified index location. It returnstrueif the items have been successfully, els...

Since its introduction in Java 8, the Stream API has become a staple of Java development. The basic operations like iterating, filtering, mapping sequences of elements are deceptively simple to use. But these can also be overused and fall into some common pitfalls. To get a better understandi...
