public static void main(String args[])
    String [] ar= {"c", "d", "b", "a", "e"};
    InnerClass in=new InnerClass();
    Arrays.parallelSort(ar, in);
    for(String str : ar)
            System.out.println(str +"");
    System.out.println(Arrays.binarySearch(ar, "b"));

I’ve edited your post for readability. When you enter a code block into a forum post, please precede it with a separate line of three backticks and follow it with a separate line of three backticks to make it easier to read.

You can also use the “preformatted text” tool in the editor (</>) to add backticks around text.

See this post to find the backtick on your keyboard.
Note: Backticks (`) are not single quotes (’).
