 Hi Guys,

Welcome to Java Inspires..

In this post, we will see how to sort an array with Stream API in Java 8.

Java8Example.java

package com.javainspires.java8example;

import java.util.Arrays;
import java.util.stream.IntStream;
import java.util.stream.Stream;

/**
 * 
 * @author Java Inspires
 *
 */
public class Java8Example {

	public static void main(String[] args) {

		// define int array
		int[] intArr = { 99, 46, 26, 88, 01, 6, 46, 5 };
		// print array before sort
		System.out.println("Before Sort");
		System.out.println(Arrays.toString(intArr));
		System.out.println();
		// convert the array to stream , here int stream
		IntStream arrayStream = Arrays.stream(intArr);
		// sort using sort method from stream
		arrayStream = arrayStream.sorted();
		// convert stream to array
		intArr = arrayStream.toArray();
		// print array after sort
		System.out.println("After Sort");
		System.out.println(Arrays.toString(intArr));
	}

}

Output:

Before Sort
[99, 46, 26, 88, 1, 6, 46, 5]

After Sort
[1, 5, 6, 26, 46, 46, 88, 99]

Thank You
