apache commons pair

Don't you think it's better to define a Pair class with word and its frequency instead of using the Pair structure from commons. A simple class encapsulating a name/value pair. (The Pair class was deliberately left out of the standard Java API.) This gives an error: import org.apache.commons.lang3.tuple.Pair; Its an abstract class, so you can't create the object directly. Use sparingly, if at all; left and right doesn't really convey anything about the content or relation between the elements. That way you can simply create a custom Comparator to define the sorting criteria based on the word (or) frequency – Arkantos Apr 28 '15 at 12:55 This factory allows the pair to be created using inference to obtain the generic types. You can vote up the ones you like or vote down the ones you don't like, and go to the original project or source file by following the links above each example. Home » org.apache.commons » commons-lang3 » 3.0 Apache Commons Lang » 3.0 Apache Commons Lang, a package of Java utility classes for the classes that are in java.lang's hierarchy, or are considered to be so standard as to justify existence in java.lang. Make sure to import the correct class to initialize your pair object. Apache Commons Lang provides the helpful Pair.of(key, value) to create an immutable, comparable, serializable pair. Commons lang library has a useful class which can used as pair i.e. public static MutablePair of(Map.Entry pair) Creates a mutable pair from an existing pair. Eclipse Collections If you're using pairs that contain primitives, Eclipse Collections provides some very efficient primitive pair classes that will avoid all … to /lib. For Commons Net you need to download the binary files from Commons Net download page. Yes, have a look at Apache Commons Pair. Then you have to extract the file and add the commons-net-2-2.jar file to some location where you can access it from your application e.g. Java Code Examples for org.apache.commons.lang3.tuple.Pair. import org.apache.commons.math3.util.Pair; Concrete Class -> Can directly create object. public class NameValuePair extends Object implements Serializable. a pair formed from the two parameters, not null; getLeft public final L getLeft() Specified by: getLeft in class org.apache.commons.lang3.tuple.Pair getRight public final R getRight() Specified by: It has two subclasses which can also be used for same purpose i.e. License Apache 2.0 Pair class is a pair consisting of two elements. Apache Commons Lang, a package of Java utility classes for the classes that are in java.lang's hierarchy, or are considered to be so standard as to justify existence in java.lang. The following examples show how to use org.apache.hadoop.hbase.util.PairOfSameType.These examples are extracted from open source projects. Pair refers to the elements as ‘left’ and ‘right’. If you want a pair (not supposedly key-value pair) just to hold two generic data together neither of the solutions above really handy since first (or so called Key) cannot be changed (neither in Apache Commons Lang's Pair nor in AbstractMap.SimpleEntry).
