java - why's this program giving a runtime error on jcreator but not on netbeans? -

-

This is my solution for the online judge of the area. It is running fine on Netbeans, but the judge rejecting my answer Is that it gives a runtime error. I tried it on JCreator and it says: 

  Exception in thread "main" java.lang.NumberFormatException: for input string: "java.lang.NumberFormatException.forInputString (NumberFormatException. Java: 48) at java.lang.Integer.parseInt (integer.javascuite68) at java.lang.Integer.parseInt (Integer. Java: 497) Main. Main (Maine Java: 73)
>

I am not passing an empty string to parse, why is this?

Code: 

  import java.io. *; Import java.util. *; Class main {public static intelglobalTatan (int no) {intestrol = 0; Int evalThisNum = ++ num; While (true) {if (ezellin (virene nnn) break); EvalThisNum ++; } FoundPalin = evalThisNum; Returned Publicin; } Public static boolean ezelline (int oculum henum) {boolean estalin = falls; Int dig = 0; Int rev = 0; Int n = evalThisNum; While (evalThisNum> 0) {dig = evalThisNum% 10; Rev = rev * 10 + dig; EvalThisNum = evalThisNum / 10; } If (n == rev) {isItPalin = true; } Return is Estelin; } Public static zero main throws java.lang.Exception {string alge []) {BufferedReader r1 = new BufferedReader (New InputStreamReader (System.in)); / * BufferedReader r1 = New BufferedReader (New FileReader (new file ("C: \\ Documents and Settings \\ Administrator \\ My Documents \ NetBens Project \\ Area \\ src \ \ sphere \\ sphere \ PALIN_INPUT.txt" ))); * Read / String = r1.readLine (); Int number of test case = integer. Persian (reading); For (int i = 0; i

Input: 

  2 808 2133

line is 73: int num = Integer.centre (read);

If you have & lt; Enter & gt; When the program is expecting a number

Assume that your input is 

  2 <3> Enter & gt;

You will be prompted after processing with error 3, just as you have asked twice to repeat it again.

On one hand, handling around the number parsing at the top of the error, you may apply the trim () to readLine () method calls Want to: 

  read the string = R1.readLine (). Trim ();

This can allow you to handle this event satisfactorily, that the user should be placed around the blank space.

c# - ListView onScroll event -

-
I am programming a simple C # application, and I need a Scallow event on the list view. So I inherited the original ListView class created in ListviewEx witch. I found out how to locate the scroll message from WinAPI and I modified the WndProc method. Now I have this WndProc: protected override zero WndProc (Ref message message) {base.WndProc (Ref I); If (m.msg == WM_VSCROLL) {onScroll (This, New EventArgs ()); }} But the problem is, I do not know how to know about scrolling information. This data should be in wParam, but there is a LOWORD macro ++ like in C in C # and I switch to find the criteria like SB_ below, SB_ENDSCROLL, SB_PAGEUP etc. there any way Need to change the LOWORD macro from C #? Or any other way to find the necessary parameters about scrolling? You can define the WParam constants as the following: Private const int WM_HSCROLL = 0x114; Private Constant WM_VSCROLL = 0x115; Private contact int SBHOZZ = 0; Private Consultant SB_VERT = 1; Private Con...

I am sending the content of an image in the body of the HTTP request (output stream) as a byte array, I want to read this stream of bytes in PHP scripts and take back an image.

Another option is to use and load the image.

Linux Terminal Problem with Non-Canonical Terminal I/O app -

-
I have a small app written in C to run on Linux. Part of the app accepts user-input from keyboard , And it uses non-canonical terminal mode so that it can respond to each keystroke. The section of the code that accepts input is a simple task that is called repeatedly in the loop: char get_input () {char C = 0; Int res = reading (input_tamille, & amp; c, 1); If (RSS == 0) 0 returns; If (res == -1) {/ * snip error handling * /} return c; } It reads a letter from the terminal if there is no input within a given time limit, (c_cc [VTIME] value in the vocabulary structure), read () 0 And get_input () is called again It all works very well, I have recently discovered that if you run this app in a terminal window, and then the app Close the terminal window without ending, the app will not exit Received, but CPU intensive launches into an infinite loop, where the read () returns 0 without waiting continued. So how can I get out of the apple if it runs from the terminal win...
