Java Question

Write a Java 8 program to iterate a Stream using the forEach method?

Accepted Answer

A Java 8 program to iterate a Stream using the forEach method.

Create a Stream object from a collection or array
Use the forEach method to perform an action on each element of the Stream
The action can be a lambda expression or a method reference

Accepted Answer

In this program, we are iterating a Stream starting from “number = 2”, followed by the count variable incremented by “1” after each iteration.

Then, we are filtering the number whose remainder is not zero when divided by the number 2. Also, we have set the limit as 5 which means only 5 times it will iterate. Finally, we are printing each element using forEach.

//Code :

import java.util.stream.*;
public class Java8 {

public static void main(String[] args){
Stream.iterate(2, count->count+1)

// Counter Started from 2, incremented by 1

.filter(number->number%2==0)

// Filtered out the numbers whose remainder is zero
// when divided by 2

.limit(5)
// Limit is set to 5, so only 5 numbers will be printed

.forEach(System.out::println);
}
}
