Getting Spliterator of Array of Objects Example
The following example shows the usage of Java Arrays spliterator(T[]) method. First, we've created an array of student objects. Using spliterator() method, array is printed thereafter.
package com.tutorialspoint;
import java.util.Arrays;
import java.util.Spliterator;
public class ArrayDemo {
public static void main(String[] args) {
// initialize array
Student arr[] = { new Student(1, "Julie"), new Student(2, "Robert"), new Student(3, "Adam"), new Student(4, "Jene") };
System.out.print("Array: [ ");
// get the spliterator
Spliterator<Student> spliterator = Arrays.spliterator(arr);
// use the spliterator to print each item
spliterator.forEachRemaining(i -> System.out.print(i + " "));
System.out.print("]");
}
}
class Student {
int rollNo;
String name;
Student(int rollNo, String name){
this.rollNo = rollNo;
this.name = name;
}
@Override
public String toString() {
return "[ " + this.rollNo + ", " + this.name + " ]";
}
}
Output
Let us compile and run the above program, this will produce the following result −
Array: [ [ 1, Julie ] [ 2, Robert ] [ 3, Adam ] [ 4, Jene ] ]
Getting Spliterator of Array of Objects using Range Example
The following example shows the usage of Java Arrays spliterator(T[], int, int) method. First, we've created an array of student objects. Using spliterator() method, array is printed thereafter.
package com.tutorialspoint;
import java.util.Arrays;
import java.util.Spliterator;
public class ArrayDemo {
public static void main(String[] args) {
// initialize array
Student arr[] = { new Student(1, "Julie"), new Student(2, "Robert"), new Student(3, "Adam"), new Student(4, "Jene") };
System.out.print("Array: [ ");
// get the spliterator
Spliterator<Student> spliterator = Arrays.spliterator(arr, 0, arr.length);
// use the spliterator to print each item
spliterator.forEachRemaining(i -> System.out.print(i + " "));
System.out.print("]");
}
}
class Student {
int rollNo;
String name;
Student(int rollNo, String name){
this.rollNo = rollNo;
this.name = name;
}
@Override
public String toString() {
return "[ " + this.rollNo + ", " + this.name + " ]";
}
}
Output
Let us compile and run the above program, this will produce the following result −
Array: [ [ 1, Julie ] [ 2, Robert ] [ 3, Adam ] [ 4, Jene ] ]
Getting Spliterator of Sub-Array of Objects Example
The following example shows the usage of Java Arrays spliterator(T[], int, int) method. First, we've created an array of student objects. Using spliterator() method, a sub-array is printed thereafter.
package com.tutorialspoint;
import java.util.Arrays;
import java.util.Spliterator;
public class ArrayDemo {
public static void main(String[] args) {
// initialize array
Student arr[] = { new Student(1, "Julie"), new Student(2, "Robert"), new Student(3, "Adam"), new Student(4, "Jene") };
System.out.print("Array: [ ");
// get the spliterator
Spliterator<Student> spliterator = Arrays.spliterator(arr, 0, 3);
// use the spliterator to print each item
spliterator.forEachRemaining(i -> System.out.print(i + " "));
System.out.print("]");
}
}
class Student {
int rollNo;
String name;
Student(int rollNo, String name){
this.rollNo = rollNo;
this.name = name;
}
@Override
public String toString() {
return "[ " + this.rollNo + ", " + this.name + " ]";
}
}
Output
Let us compile and run the above program, this will produce the following result −
Array: [ [ 1, Julie ] [ 2, Robert ] [ 3, Adam ] ]
