Hello ,everyone!

No matter what i input,it just outputs that i have inputed!
Why when i input "Nice to meet you!",it is also output "Nice to meet you!" not "Nice to meet you too!"?

Have you checked the length of the string you are creating from the byte buffer?

read() is going to return any newline characters you type; does that help?

When you press enter after feeding in from the console, two characters are concatenated to your already entered string -- the linefeed and the new line ('\r' and '\n').

That is why you will see that the length of the entered string is always more by 2 characters. If you enter one character and do a string.length(), you will see it prints 3.

A one line addition makes your code work. Before you compare the two strings, add this:



Hope it helped!
