Answer 1

A scanner breaks its input into tokens using a delimiter pattern, which is by default known the Whitespaces.

Next() uses to read a single word and when it gets a white space,it stops reading and the cursor back to its original position. NextLine() while this one reads a whole word even when it meets a whitespace.the cursor stops when it finished reading and cursor backs to the end of the line. so u don't need to use a delimeter when you want to read a full word as a sentence.you just need to use NextLine().

 public static void main(String[] args) {
            // TODO code application logic here
           String str;
            Scanner input = new Scanner( System.in );
            str=input.nextLine();
            System.out.println(str);
       }
