The fromArray() method in org.javatuples is used to instantiate a tuple in a semantically elegant way, with the values of the array, given as parameters. This method can be used to any tuple class object of javatuples library. It is a static function in each javatuple class and it returns the tuple class object of the called class, with the values initialized by the corresponding values of the array.
Method Declaration:
Java
Output:
Java
Output:
public static <X> TupleClass<X> fromArray(X[] array)Syntax:
TupleClass<X> obj = TupleClass.fromArray(X[] array)Parameters: This method takes array as parameter where:
- X- represents the datatype of values in the array.
- array- represents the array of values to be inserted into TupleClass.
- TupleClass- represents the JavaTuple Class used like Unit, Quintet, Decade, etc.
// Below is a Java program to create
// a Unit tuple from fromArray() method
import java.util.*;
import org.javatuples.Unit;
class GfG {
public static void main(String[] args)
{
// Creating an array with one value
String str[] = { "GeeksforGeeks" };
// Using fromArray() method
Unit<String> unit = Unit.fromArray(str);
System.out.println(unit);
}
}
[GeeksforGeeks]Program 2: Using fromArray() with Decade class:
// Below is a Java program to create
// a Unit tuple from fromArray() method
import java.util.*;
import org.javatuples.Decade;
class GfG {
public static void main(String[] args)
{
// Creating an array with 10 value
String str[] = { "Geeks",
"for",
"Geeks",
"A",
"Computer",
"Science",
"Portal",
"for",
"Geeks",
"RishabhPrabhu" };
// Using fromArray() method
Decade<String, String, String, String, String,
String, String, String, String, String>
decade = Decade.fromArray(str);
System.out.println(decade);
}
}
[Geeks, for, Geeks, A, Computer, Science, Portal, for, Geeks, RishabhPrabhu]Note: Similarly, it can be used with any other JavaTuple Class.
