array of tuples java

Also, in Java, part of the tuple functionality can be written using List or Array but those will not allow us to hold different types of data types by design. addAt0(X0 value0, X1 value1) returns Sextet and so on upto addAt0() with six parameters. removeAt1() − remove value at index 1 and return the resulted tuple. addAt0(X0 value0, X1 value1) returns Quintet and so on upto addAt0() with seven parameters. In this tutorial, we'll learn different ways to return multiple values from a Java method. Tuples allow you to express an array with a fixed number of elements of which each element may be of a different type. I have some quick and dirty conversion code, and wondered how it could be improved and perhaps made more generic. To work with Unit class in JavaTuples, you need to import the following package −. Following is the declaration for org.javatuples.KeyValue class −, static KeyValue fromArray(X[] array), static KeyValue fromCollection(Collection collection), static KeyValue fromIterable(Iterable iterable), static KeyValue fromIterable(Iterable iterable, int index), static KeyValue with(A value0, B value1). Each setAtX() returns a new tuple which is to be used to see the updated value. Following is the declaration for org.javatuples.Quartet class −, Quartet(A value0, B value1, C value2, D value3). Similarly other methods to add values are available e.g. How to implement Pair class using Unit class? Similarly getValue1() upto getValue8() returns the value at index 1 and so on. Following is the declaration for org.javatuples.Ennead class −, Ennead(A value0, B value1, C value2, D value3, E value4, F value5, G value6, H value7, I value8). add(Pair tuple) returns Octet and upto add(Quartet tuple) returns Decade tuple.
