JavaTuples – Quick Guide ”; Previous Next JavaTuples – Overview Tuple Tuple is a sequence of objects which may or may not be of same type. Consider the following example − [12,”TutorialsPoint”, java.sql.Connection@li757b] Above object is a tuple of three elements, an Integer, a string and a Connection Object. JavaTuple JavaTuples is a very simple library which offers ten different tuple classses which are sufficient to handle most of the tuple related requirements. Unit<A> – 1 element Pair<A,B> – 2 elements Triplet<A,B,C> – 3 elements Quartet<A,B,C,D> – 4 elements Quintet<A,B,C,D,E> – 5 elements Sextet<A,B,C,D,E,F> – 6 elements Septet<A,B,C,D,E,F,G> – 7 elements Octet<A,B,C,D,E,F,G,H> – 8 elements Ennead<A,B,C,D,E,F,G,H,I> – 9 elements Decade<A,B,C,D,E,F,G,H,I,J> – 10 elements Apart from these tuple classes, JavaTuples also provides two additional classes for semantics sake. KeyValue<A,B> LabelValue<A,B> All tuple classes are typesafe and immutable and implements following interfaces and methods. Iterable Serializable Comparable<Tuple> equals() hashCode() toString() Tuple vs List/Array List or Array can contain any number of elements but each element must be of same type whereas tuples can contain only specific number of elements, can have different type of elements but still are typesafe. JavaTuples – Environment Setup Local Environment Setup If you are still willing to set up your environment for Java programming language, then this section guides you on how to download and set up Java on your machine. Please follow the steps mentioned below to set up the environment. Java SE is freely available from the link Download Java. So you download a version based on your operating system. Follow the instructions to download Java and run the .exe to install Java on your machine. Once you have installed Java on your machine, you would need to set environment variables to point to correct installation directories − Setting up the Path for Windows 2000/XP We are assuming that you have installed Java in c:Program Filesjavajdk directory − Right-click on ”My Computer” and select ”Properties”. Click on the ”Environment variables” button under the ”Advanced” tab. Now, alter the ”Path” variable so that it also contains the path to the Java executable. Example, if the path is currently set to ”C:WINDOWSSYSTEM32”, then change your path to read ”C:WINDOWSSYSTEM32;c:Program Filesjavajdkbin”. Setting up the Path for Windows 95/98/M We are assuming that you have installed Java in c:Program Filesjavajdk directory − Edit the ”C:autoexec.bat” file and add the following line at the end − ”SET PATH=%PATH%;C:Program Filesjavajdkbin” Setting up the Path for Linux, UNIX, Solaris, FreeBS Environment variable PATH should be set to point to where the Java binaries have been installed. Refer to your shell documentation if you have trouble doing this. Example, if you use bash as your shell, then you would add the following line to the end of your ”.bashrc: export PATH=/path/to/java:$PATH” Popular Java Editor To write your Java programs, you need a text editor. There are many sophisticated IDEs available in the market. But for now, you can consider one of the following − Notepad − On Windows machine you can use any simple text editor like Notepad (Recommended for this tutorial), TextPad. Netbeans − It is a Java IDE that is open-source and free which can be downloaded from www.netbeans.org/index.html. Eclipse − It is also a Java IDE developed by the eclipse open-source community and can be downloaded from www.eclipse.org. Download JavaTuples Archie Download the latest version of JavaTuples jar file from Maven Repository – JavaTuples. In this tutorial, javatuples-1.2.jar is downloaded and copied into C:> javatuples folder. OS Archive name Windows javatuples-1.2.jar Linux javatuples-1.2.jar Mac javatuples-1.2.jar Set JavaTuples Environment Set the JavaTuples environment variable to point to the base directory location where JavaTuples jar is stored on your machine. Assuming, we”ve extracted javatuples-1.2.jar in JavaTuples folder on various Operating Systems as follows. OS Output Windows Set the environment variable JavaTuples to C:JavaTuples Linux export JavaTuples=/usr/local/JavaTuples Mac export JavaTuples=/Library/JavaTuples Set CLASSPATH Variable Set the CLASSPATH environment variable to point to the JavaTuples jar location. Assuming, you have stored javatuples-1.2.jar in JavaTuples folder on various Operating Systems as follows. OS Output Windows Set the environment variable CLASSPATH to %CLASSPATH%;%JavaTuples%javatuples-1.2.jar;.; Linux export CLASSPATH=$CLASSPATH:$JavaTuples/javatuples-1.2.jar:. Mac export CLASSPATH=$CLASSPATH:$JavaTuples/javatuples-1.2.jar:. JavaTuples – Create Tuples A tuple using JavaTuple classes can be created using multiple options. Following are the examples − Using with() Methods Each tuple class has a with() method with corresponding parameters. For example − Pair<String, Integer> pair = Pair.with(“Test”, Integer.valueOf(5)); Triplet<String, Integer, Double> triplet = Triplet.with(“Test”, Integer.valueOf(5), Double.valueOf(32.1)); Using Constructor Each tuple class has a constructor with corresponding parameters. For example − Pair<String, Integer> pair = new Pair(“Test”, Integer.valueOf(5)); Triplet<String, Integer, Double> triplet = new Triplet(“Test”, Integer.valueOf(5), Double.valueOf(32.1)); Using Collections Each tuple class has a fromCollection() method with corresponding parameters. For example − Pair<String, Integer> pair = Pair.fromCollection(listOfTwoElements); Using Iterable Each tuple class has a fromIterable() method to get elements in generic fashion. For example − // Retrieve three values from an iterable starting at index 5 Triplet<Integer,Integer,Integer> triplet = Triplet.fromIterable(listOfInts, 5); Example Let”s see JavaTuples in action. Here we”ll see how to create tupels using various ways. Create a java class file named TupleTester in C:>JavaTuples.
