First of all, please, UseCodeTags ← click this
I added them for you this time.

Second, please, don't post your questions as comments. They may not be noticed by someone wanting to help.

Third, you should specify what don't you understand.
Is is this strange looking syntax with question mark and a colon? It is called ternary operator. You can read something about it here.

To put it simple:
condition ? value1 : value2
This expression will yield value1 if condition is true and value2 otherwise.

Hello Sunit,

What Pawel said is right. You will learn more if you follow his guidelines.

To answer you question, Boolean.valueOf() returns boolean value true or false if the string argument is not null and is equal, ignoring case, to the string "true".

Since you are passing "True", it will return true each time. Now ternary operator will return first argument if condition is true, so it will return "bye"

In short, it will print "byebye"
