El método toArray() de Java AbstractSequentialList se utiliza para formar una array de los mismos elementos que la de AbstractSequentialList. Básicamente, copia todo el elemento de una AbstractSequentialList a una nueva array.
Sintaxis:
Object[] arr = AbstractSequentialList.toArray()
Parámetros: El método no toma ningún parámetro.
Valor devuelto: el método devuelve una array que contiene elementos similares a AbstractSequentialList.
Los siguientes programas ilustran el método AbstractSequentialList.toArray():
Programa 1:
// Java code to illustrate toArray()
import java.util.*;
public class AbstractSequentialListDemo {
public static void main(String args[])
{
// Creating an empty AbstractSequentialList
AbstractSequentialList<String>
abs_col = new LinkedList<String>();
// Use add() method to add
// elements into the AbstractSequentialList
abs_col.add("Welcome");
abs_col.add("To");
abs_col.add("Geeks");
abs_col.add("For");
abs_col.add("Geeks");
// Displaying the AbstractSequentialList
System.out.println("The AbstractSequentialList: "
+ abs_col);
// Creating the array and using toArray()
Object[] arr = abs_col.toArray();
System.out.println("The array is:");
for (int j = 0; j < arr.length; j++)
System.out.println(arr[j]);
}
}
Producción:
The AbstractSequentialList: [Welcome, To, Geeks, For, Geeks] The array is: Welcome To Geeks For Geeks
Programa 2:
// Java code to illustrate toArray()
import java.util.*;
public class AbstractSequentialListDemo {
public static void main(String args[])
{
// Creating an empty AbstractSequentialList
AbstractSequentialList<Integer>
abs_col = new LinkedList<Integer>();
// Use add() method to add
// elements into the AbstractSequentialList
abs_col.add(10);
abs_col.add(15);
abs_col.add(30);
abs_col.add(20);
abs_col.add(5);
abs_col.add(25);
// Displaying the AbstractSequentialList
System.out.println("The AbstractSequentialList: "
+ abs_col);
// Creating the array and using toArray()
Object[] arr = abs_col.toArray();
System.out.println("The array is:");
for (int j = 0; j < arr.length; j++)
System.out.println(arr[j]);
}
}
Producción:
The AbstractSequentialList: [10, 15, 30, 20, 5, 25] The array is: 10 15 30 20 5 25
