Question

Say I had the Scanner method, and I want to print the user input after that.

Take this code for instance:

    String randomWords;
    Scanner kb = new Scanner(System.in);

    System.out.print("Please enter two words separated: ");

    randomWords = kb.next();    
    System.out.println(randomWords);

And if the two separated words entered were

hello world

Only

hello 

is printed

Why is this? and how can I print both of the words with the space included?

Thank you.

Use Scanner#nextLine() instead,

This method returns the rest of the current line, excluding any line
separator at the end.

randomWords = kb.nextLine();    

Scanner#next() reads the next complete token basing on the delimiter.

Finds and returns the next complete token from this scanner. A
complete token is preceded and followed by input that matches the
delimiter pattern

As default delimiter of the scanner is whitespace, you should explicitly define the delimiter for your scanner using Scanner#useDelimiter(str).
If you use \n next line as delimiter your curretn code would work.

 Scanner kb = new Scanner(System.in).useDelimiter("\n");
    System.out.print("Please enter two words separated: "); 
    randomWords = kb.next();    
    System.out.println(randomWords);
