Printing string variable in Java

Question

I m getting some weird output when running  seemingly simple  code  Here s what I have   import java util Scanner   public class TestApplication     public static void main String   args        System out println  Enter a password          Scanner input   new Scanner System in       input next        String s   input toString        System out println s           And the output I get after compiling successfully is   Enter a password   hello java util Scanner delimiters  p javaWhitespace    position 5  match valid true  need input false  source closed false  skipped false  group separator     decimal separator     positive prefix   negative prefix  Q- E  positive suffix   negative suffix   NaN string  Q  E  infinity string  Q8 E    Which is sort of weird  What s happening and how do I print the value of s

input next    String s   input toString      change it to  String s   input next      May be that s what you were trying to do

This is more likely to get you what you want   Scanner input   new Scanner System in   String s   input next    System out println s

You re getting the toString   value returned by the Scanner object itself which is not what you want and not how you use a Scanner object  What you want instead is the data obtained by the Scanner object   For example   Scanner input   new Scanner System in   String data   input nextLine    System out println data     Please read the tutorial on how to use it as it will explain all     Edit Please look here  Scanner tutorial  Also have a look at the Scanner API which will explain some of the finer points of Scanner s methods and properties

You could also use BufferedReader   import java io     public class TestApplication      public static void main  String   args          System out print  Enter a password            BufferedReader br   new BufferedReader new InputStreamReader System in          String password   null        try            password   br readLine            catch  IOException e             System out println  IO error trying to read your password              System exit 1                 System out println  Successfully read your password

You are printing the wrong value  Instead if the string you print the scanners object  Try this  Scanner input   new Scanner System in   String s   input next    System out println s

If you have tried all the other answers  and it still hasn t work  you can try skipping a line   Scanner scan   new Scanner System in   scan nextLine    String s   scan nextLine    System out println  String is     s
