JavaTuple toArray() method

The toArray() method in org.javatuples is used to convert the values in TupleClass into an array of Object type. This method is inherited from the JavaTuple class. This method can be used to any tuple class object of javatuples library. It returns an array of Object type formed with the values in the TupleClassObject.

Method Declaration:

public final Object[] toArray()

Syntax:

Object obj[] = TupleClassObject.toArray()

Here TupleClassObject represents the JavaTuple Class object used like Unit, Quintet, Decade, etc.

Return Value: This method returns an array of Object type formed with the values in the TupleClassObject.

Below are programs that will illustrate the various ways to use toArray() method:

Program 1: Using toArray() with Unit class:

// Below is a Java program to use toArray() method 
  
import java.util.*; 
import org.javatuples.Unit; 
  
class GfG { 
    public static void main(String[] args) 
    { 
        // Creating an Unit with one value 
        Unit<String> unit = Unit.with("GeeksforGeeks"); 
  
        // Using toArray() method 
        Object[] object = unit.toArray(); 
  
        // Printing the array elements 
        for (Object obj : object) { 
            System.out.println(obj); 
        } 
    } 
} 

Output:

GeeksforGeeks

Program 2: Using toArray() with Quartet class:

// Below is a Java program to use toArray() method 
  
import java.util.*; 
import org.javatuples.Quartet; 
  
class GfG { 
    public static void main(String[] args) 
    { 
        // Creating a quartet 
        Quartet<Integer, String, String, Double> quartet 
            = Quartet.with(Integer.valueOf(1), 
                           "GeeksforGeeks", 
                           "A computer portal", 
                           Double.valueOf(20.18)); 
  
        // Using toArray() method 
        Object[] object = unit.toArray(); 
  
        // Printing the array elements 
        for (Object obj : object) { 
            System.out.println(obj); 
        } 
    } 
} 

Output:

1
GeeksforGeeks
A computer portal
20.18

Note: Similarly, it can be used with any other JavaTuple Class.
