how to code a for loop using a 2 dimensional array -

-

I am just learning Java and participating in a problem while completing an assignment. I need to use for the loop, but I have uncertainty about proper coding. I was able to compile my code to get the output for the first challenge, but I am unable to do this for the remaining challenges. Any tips / tips are greatly appreciated 

  / Your trainer is in the bind, instead of his work, a new // technology project has been established, which will require remote access verification. // In addition to his username and password, he will have a "challenge" // Every sign-on will require that challenge that it depends on a number or / or letter that asks the security application. // But your instructor is lazy he wants an application that will tell him what he is / without telling them that without the proper numbers, what should they do to do them // should be shown every time. He understands that this film will help // remote hackers, but he does not want to be trapped in carrying around a piece of paper at all times. // Write your instructor a program, which asked him for three characters. The matrix to use is: // ABCDEFGHI1 // 1 3N1M4 Rx5FN / 2NVT5KKFM3P / 3WKY4VT4VTF3/4339V4YRTNN/53 1 1 3 2 9 XPNP / A1: B2: A Challenge 3V1 will be generated. A challenge of G4: D2: J3RR 3 3/1 will generate 1. 1. Input / ---- make a scanner class 2. 2. Input String input = Ask for "A1" ; // 3. Take the character before the challenge / (like "D2" is "D" and its corresponding integer array value) int i1 = Util.findFirstValue (input); Println (i1); // 4. Take the second character from the challenge (like "D2" will be // "2") and its corresponding int array value // signal: always be one less than the value entered. Int i2 = Util.findSecondValue (Input); Println (i2); // 5. In order to obtain the desired value System.out.println (Util.findArrayValue (i1, i2)), query the array with the challenge values; // 6. Display price 7. 7. Repeat steps 2 to 6} {for (int row = 1; row & lt; 9; line ++) {for (int column = 2; column & lt; 5 To make it looping through the column + multi-dimensional arrays, it should be preferred.  
 
 
 
 For 
  (int i = 0; i & lt; multarray [i]. Length; i ++) {multirayare [i] [k]; // do something with it!}   
 You can find out about iterating the multi-dimension array in Java.

ios - Adding an SKSpriteNode to SKScene from a child SKSpriteNode -

-
I have a SKScene where I am adding an SKSpriteNode I have subclassed the SKSpriteNode class to create this node. In the subclass I am defining some SKActions on Sprite. What do I want to do when the end of this phantom ends the SKAction sequence, then I add a new Prayer node to this scene. How is this possible. The following code is mine: The code for the sequence is that I'm running on the Scansprinitode subclass (TEMissileNode): - SKAction * moveDown = [SKAction moveToY: Self.position.y - 20 Duration: 0.2]; SKAction * animation = [SKAction animateWithTextures: textures timePerFrame: time / 7]; SKAction * moveMissileProjectile = [SKAction Moving: Pointoffscreen Term: Time]; SKAction * group = [SKAction group: @ [animation, movement projectile]]; SKAction * Sequence = [SKAction Sequence: @ [Hilldown, Group, [SKAction removalFromParent]]]; [Self run action: sequence]; From the main scene, I call those actions that execute these tasks TEMissileNode * missile = [tmissil...

Matlab transpose a table vector -

-
An embarrassing simple question seems to be, but how can I move a Matlab table vector? aTableT = aTable '; I tried a standard syntax for the simple interaction of a line vector to a line vector aTable : ATableT = reshape (aTable, 1, Height (aTable)); and aTableT = rot90 (aTable); According to the head, the last time table should work for table, see. However, I get this error code: Error type in using table / permit (line 396) Undefined function 'permute' for the input arguments. Error in rot 90 (line 29) b = magnitude (b, [2 1 3: ndims (a)]); NB: fliplr is not useful either pretty sure I have covered clear angles - any ideas? Thanks! Try changing your table into an array, move it, then back to a table In other words, try doing this: aTableArray = table2array (aTable); ATableT = array 2table (aTableArray. '); I have also read the document for rot90 , and it says that rot90 is definitely working for tables Do, and I find you...

c# - Textbox not clickable but editable -

-
I have a small form with 10 text boxes, I have set them in the correct tab order. I want them on my tab service I was wondering if there is a way to set the text box so that they can be selected for editing until they are tabbed. That is ... I do not want the end user to edit the text box to click on them, I just want to make them editable through tabu. this should do the trick public partial category poor text box: Text Box {Safe Override Zero WndProc (Ref: Message Message) {if (m.msg == (Int) WM.LBUTTONDOWN) {Return; // mount down events} base.WndProc (ref m); }} Window message enum can be found. How to do this without anherizing: text box : class EatMouseDown: netwindows {safe override zero WndProc (ref message message) {if (m.msg == (int) WM.LBUTTONDOWN) {return; } Base.WandProc (Ref M); }} Safe Override Zero Onload (EventEurge E) {base.OnLoad (e); How to do this without any part: left a clean part, whatever is important, this can be a buggy but it works R...
