how to solve the java.lang.NullPointerException? -

-

This is what I wrote for snakes and stairs. Please help me with the exceptions. The exception line is 72 and 114, I have highlighted the lines with comments that are heading towards the exception. Thanks in advance for the help. 

  Package Practical 1; Import Java.io.Console; Import java.util.ArrayList; Import java.util.Scanner; Public square snakeandladder1 {int totalpos = 100; Int v = 0; Int [] score; Int score = 0; Int l = 0; Public Ink Foradis () {int i = 0; {While (i == 0) {i = (Math) Random () * 100; I = I% 13; } Came back; }} Public Anti Lender (Int Score) {if (Score == 15) Score = 30; And if (score == 45) score = 71; And if (score == 25) score = 62; And if (score == 81) score = 91; And if (score == 9) points = 39; Score [l] = score; Return score; } Public sank snat (int score) {if (score == 29) score = 11; And if (score == 81) score = 48; And if (score == 92) score = 71; And if (score == 30) score = 6; And if (score == 58) points = 19; Score [l] = score; Return score; } Zero Start () {System.out.println ("Enter the number of players:"); Scanner = new scanner (System.in); Int n = in.nextInt (); In.close (); L = n; System.out.println ("Enter Player Name in Order:"); ArrayList & LT; String & gt; Name 1 = New Arrestist & lt; String & gt; (); (For int i = 0; i & lt; n; i ++) {console = 1 in System.console (); String name 2 = in 1 Readline (); // ---- I'm getting this tap pointer exception here. Name1.add (NAME2); } While (true) {while (L> gt; {}} {System.out.println ("wx rolling die% d" + (L + 1)); Console in2 = System.console (); String Yes = in2.readLine (); If (yes == "Y") {v = throwdice (); } Score = score [L] + V; ((// ---) if all user input for scanner is replaced by empty indicator exception) (score == overall) {System.out.println ("user:" + name1.get (l) + " Found "+ v +" winner !!! "); break; } And if (score> placement) {score [l] = score [l]; } Int s1; S1 = ladder (score); If (S1 == score) {snake (score); } System.out.println ("present point" + 1 name .get (L) + "is:" + score [L]); L--; } If (L == 0) {l = n; }}} Public static zero master (string [] args) throws exceptions {// Todo auto-generated method stub snake and leader 1 cell = new sniper welder 1 (); ((// tap pointer exception even after the change here)) sal.start (); // ------ I'm getting this tap pointer exception here}   
}   
 
 
  scanner = new scanner (System.in); Int n = in.nextInt (); In.close ();   
 Please note that the  close ()  method in the above code will not only close the object  scanner  but also the stream below it It will not be (i.e. keyboard input) from  System.in  and all other sources that implement  readable .  
 
 When an < shutdown  interface applies.   
 My suggestion:   The scanner  is closed, it will close its input source if the source  Closeable  Ul> < Li>  in.close ();   
  •  Use  name2 = in.readLine ();

    python - Receiving "KeyError" after decoding json result from url -

    -
    I am new to Python I am trying to parse JSON result from a URL. Basically, I was using the following: response = urllib.request.urlopen (url) json_obj = json.load (response) It should be a stroke "str 'not' bytes' in the lines of a given" JSON object, so after searching on the StackoverView Flo, I decode the response in this way: F = urllib.request.urlopen (Url) charset = f.info (). Get_param ('charset', 'utf8') data = f.read () decoded = json.loads (data.decode (charset)) If I print "decode" I is as follows: { 'link': { 'summary data': 'https: // localhost / piwebapi / streams / p0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / summary' 'value': 'https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / price ',' InterpolatedData ':' https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTE...

    .net - Creating a new Queue Manager and Queue in Websphere MQ (using C#) -

    "itemprop =" text "> I am writing applications that use WebSphere MQ to send messages. My unittests (for flow), I want to verify that I have put the correct message on the response queue. I am trying to figure out how to do this. My main obstacle is that I think it might be scary to clear the queue before running in my queue because the same queue can be used by other applications, I thought a decent solution would be a new line The manager will remove the queue for my solidarity and after using it. So my question is: Is it possible to use C # by using queue manager and queue? After the For future reference and future people, who want to make queues. I thought how to make and remove IBM MQ QE (not quenhers) with PCM messaging. It is not very simple, but it can be done. We have implemented it in a library and it is being used to create and delete commands before and after integration tests. The most important part of the code in this library is shown in the...
