What are people using old (and expensive) Amigas for today? static Octet with(A value0, B value1, C value2, D value3, E value4, F value5, G value6, H value7). addAt0(Pair value) returns Ennead and so on upto addAt0(Triplet). A tuple has add() method at the end of a tuple and it changes the type of tuple as well. Notepad − On Windows machine you can use any simple text editor like Notepad (Recommended for this tutorial), TextPad. Netbeans − It is a Java IDE that is open-source and free which can be downloaded from www.netbeans.org/index.html. Similarly other methods to add values are available e.g. Other similar method are addAt1(Unit value) which add a unit at index0 and have similar methods upto addAt2(Octet). In this tutorial, we'll learn different ways to return multiple values from a Java method. In JavaScript, arrays already allow multiple types to be grouped. Let's see JavaTuples in action. 2. But for now, you can consider one of the following −. We can access tuple by referring to the index number inside the square brackets. getValue(index) − returns value at index starting from 0. getValueX() methods are typesafe and no cast is required, but getValue(index) is generic. Then you can use Collections.sort to do the actual work. Similarly other methods to add tuples are available e.g. Other similar method are addAt1(X0 value) which add a value at index0 and have similar methods upto addAt5() with four parameters. A tuple is a collection of several elements that may or may not be related to each other. indexOf(element) − returns the index of first element if present otherwise -1. lastIndexOf(element) − returns the index of last element if present otherwise -1. Similarly setAt1() upto setAt6() set the value at index 1, and so on. For example Triplet class has following methods. JavaTuples is a very simple library which offers ten different tuple classses which are sufficient to handle most of the tuple related requirements. However, data of different data types cannot hold on this. Similarly other methods to add values are available e.g. add(X0 value0, X1 value1) returns Decade.
