the scanf is not executed before the first puts, it is only the visible effect which gets delayed.

ending the program causes final output of anything buffered.

If the scanner is already closed then on calling this method, it will have no effect. The close () method of class closes the scanner which has been opened.

your program does not do anythign visible, though executing completly Scanner close () method in Java with Examples.

(this is where I propose to flush in order to get output).

environment is configured not to automatically output immediatly.

In your case the buffering causes this sequence: In scanner class, we have the next() method which reads one word at a time, and nextLine(). */Īt exactly the point where you need the output you have already send. There are two different options:- read one word or read one line. The Scanner class reads an entire line and divides the line into tokens. next() function returns the next token/word in the input as a string and charAt(0) function returns the first character in that string. there must be something special in your environment, I suspect the Eclipse console, but that is just guessing.Įspecially when attempting to do prompt and reading within one line, it is wise to use a /*. To read a single character, we use next().charAt(0). Usually a newline at the end of text is sufficient, i.e.

Depending on how the buffering of the output is configured, you might nee to be very explicit about when to actually make the output.
