Following are JDK 1.8 Features Read one-by-one as they are very innteresting. 1. Method References a) With static method:

import java.util.Arrays;
class Test 
{
  public static int matchStringLength(String str1, String str2)
  {
    return str1.length() - str2.length();
  }
}
public class Demo 
{
  public void printByStringLength() 
  {
    String names[] = {"abcde","abc","ab","abcd", "a"};
    Arrays.sort(names, Test::matchStringLength);
        
    System.out.println(Arrays.toString(names));
    } 
    public static void main(String args[])
    {
        new Demo().printByStringLength();
   }
}

import java.util.Arrays;

class Test

{

public static int matchStringLength(String str1, String str2)

{

return str1.length() - str2.length();

}

public class Demo

{

public void printByStringLength()

{

String names[] = {"abcde","abc","ab","abcd", "a"};

Arrays.sort(names, Test::matchStringLength);

System.out.println(Arrays.toString(names));

}

public static void main(String args[])

{

new Demo().printByStringLength();

}

Arrays.sort(names, Test::matchStringLength); You can call the methods with their names (references) with :: operator. 2. Parallel Sort

import java.util.Arrays;
public class Demo 
{
  public static void main(String args[])
  {
    String fruits[] = {"guava","apple","banana"};
    String fruits1[] = {"guava","apple","banana"};

                                      // before JDK 1.8, using Arrays.sort()

    Arrays.sort(fruits);
    System.out.println(Arrays.toString(fruits));

                                       // with JDK 1.8, using Arrays.parallelSort()
    Arrays.parallelSort(fruits1);
    System.out.println(Arrays.toString(fruits1));
  }
}

import java.util.Arrays;

public class Demo

{

public static void main(String args[])

{

String fruits[] = {"guava","apple","banana"};

String fruits1[] = {"guava","apple","banana"};

// before JDK 1.8, using Arrays.sort()

Arrays.sort(fruits);

System.out.println(Arrays.toString(fruits));

// with JDK 1.8, using Arrays.parallelSort()

Arrays.parallelSort(fruits1);

System.out.println(Arrays.toString(fruits1));

}

Both sort() and parallelSort() sorts the array. The performance with parallelSort() can…
