Yet another Tuple library for Java 8 and up.
Add to pom.xml:
<dependencies>
<dependency>
<groupId>com.andrebreves</groupId>
<artifactId>java-tuple</artifactId>
<version>1.2.0</version>
</dependency>
</dependencies>Java 8:
Tuple2<String, String> tuple = Tuple.of("v01", "v02");
System.out.println(tuple.v1()); // "v01"
System.out.println(tuple.v2()); // "v02"
Tuple3<String, String, String> newTuple = tuple.concat("v03");
System.out.println(newTuple.v1()); // "v01"
System.out.println(newTuple.v2()); // "v02"
System.out.println(newTuple.v3()); // "v03"
List<Tuple3<String, Integer, String>> tuples = Arrays.asList(
Tuple.of("v10", 11, "v12"),
Tuple.of("v20", 21, "v22"),
Tuple.of("v30", 31, "v32")
);
tuples.stream()
.map(Tuple::v3)
.forEachOrdered(System.out::print); // "v12v22v32"Java 10 and up:
