Running code taking undefined number of inputs in Netbeans

Question

I have a code that takes input using scanner but the number of input is not defined. How to run the code in Netbeans?

The code is as follows:

Scanner scan = new Scanner(System.in);
while(scan.hasNextLine()){
    // print the token
    System.out.println(scan.next());
}
scan.close();

When I run the code, it is only taking input and no further processing is done.

In your code, You are just printing the input to output stream. what type of processing do you want? — Yohannes Gebremariam, Feb 28 '17 at 18:33
For the record: this has **nothing** to do with the IDE that you are using. No need to put a netbeans tag on a pure java question! — GhostCat, Feb 28 '17 at 18:41

I assume you want to take input, then print it?

Put in something like:

String s = scan.next();

before the while loop.

Not sure what your input looks like, so maybe try changing

hasNextLine()

to just

hasNext()
