How to mask a password in Java 5?

I am trying to mask a password in Java. Sun java has suggested a way to mask a password as follows. Masking a password It uses a simple way to do that. public void run () { stop = true; while (stop) { System.out.print("\010*"); try { Thread.currentThread().sleep(1); } catch(InterruptedException ie) { ie.printStackTrace(); } } } But this approach has several drawbacks. If the user uses the arrow keys + delete keys the password gets revealed. If the user accidentally press 2 keys at the same time (Extremely high typing speed) some characters does not get masked. Do you guys think of any way that

问题 I'm creating a simple player app. There is a circle, that shows a progress of playing a song. What is the best way to draw this circle in Swift and make a mask? I assume I can draw a 2 circles putting the width stroke to the thickness I want and without filling it. And the white one has to be masked according to some parameter. I don't have an idea, how to mask it in a proper way. 回答1: I came up with this solution recently: class CircularProgressView: UIView { private let floatPi = CGFloat(M

HTML Form Field - How to require an input format

由 醉酒当歌 提交于 2019-12-01 08:33:12
What I want to do here is require that phone numbers be entered into my HTML form as (XXX) XXX-XXXX and that SS Numbers are entered as XXX-XX-XXXX. Thats it. The only reason I am doing this is so that the form submission results are consistent and easy exported to Excel. I have been told to use Javascript to do this but perhaps I am not advanced enough to understand all the steps in doing that. Can someone please point me in the right direction here keeping in mind that I am a beginner? Wow thank you so much Ethan and @suman-bogati! I am ALMOST there now! The field now pops an error stating to

I've added a JQuery Masked Input plugin to my Web project but it's not working at all. The plugin can be found here: http://digitalbush.com/projects/masked-input-plugin I've included JQuery libray and the Masked Input plugin to my JSP, and called the mask function for my html <input> element: <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <!-- JS ---> <script src="js/jquery-1.11.0.js"></script> <script src="js/masked-input-jquery-1.3.1.js"></script> <title>Test</title> </head> <body> <script type="text/javascript"> $("#name").mask("99/99/9999"); </script>

mask all digits except first 6 and last 4 digits of a string( length varies )

由 孤街浪徒 提交于 2019-11-30 11:11:30
I have a card number as a string, for example: string ClsCommon.str_CardNumbe r = "3456123434561234"; The length of this card number can vary from 16 to 19 digits, depending on the requirement. My requirement is that I have to show the first six digits and the last 4 digits of a card number and mask the other characters in between with the character 'X'. I have tried using subString and implemented it separately for 16,17,18,19 digits.. I split string(ClsCommon.str_CardNumber) to 5 strings (str_cardNum1, str_cardNum2, str_cardNum3, str_cardNum4, str_cardNum5 - 4 digits for each string.

tensorflow creating mask of varied lengths

由 我们两清 提交于 2019-11-30 06:56:14
I have a tensor of lengths in tensorflow, let's say it looks like this: [4, 3, 5, 2] I wish to create a mask of 1s and 0s whose number of 1s correspond to the entries to this tensor, padded by 0s to a total length of 8. I.e. I want to create this tensor: [[1,1,1,1,0,0,0,0], [1,1,1,0,0,0,0,0], [1,1,1,1,1,0,0,0], [1,1,0,0,0,0,0,0] ] How might I do this? This can be achieved using a variety of TensorFlow transformations : # Make a 4 x 8 matrix where each row contains the length repeated 8 times. lengths = [4, 3, 5, 2] lengths_transposed = tf.expand_dims(lengths, 1) # Make a 4 x 8 matrix where

What is the purpose of “int mask = ~0;”?

由 不想你离开。 提交于 2019-11-30 05:35:54
I saw the following line of code here in C. int mask = ~0; I have printed the value of mask in C and C++. It always prints -1 . So I do have some questions: Why assigning value ~0 to the mask variable? What is the purpose of ~0 ? Can we use -1 instead of ~0 ? It's a portable way to set all the binary bits in an integer to 1 bits without having to know how many bits are in the integer on the current architecture. C and C++ allow 3 different signed integer formats: sign-magnitude, one's complement and two's complement ~0 will produce all-one bits regardless of the sign format the system uses. So

Easiest way to mask characters in HTML(5) text input

由 南笙酒味 提交于 2019-11-30 04:48:38
Does HTML5 have any kind of text field masking or do I still have to trap onkeydown etc.? jbabey is right--"masking" as in blocking certain illegal characters, not hiding what's typed. The best (as in simplest and most reliable) way I've found is to trap onkeyup and then just run a regex replace on the value of the textfield, removing any illegal characters. This has a few advantages: It's easy to implement (one function, two lines of code). It's reliable and covers all cases I've thought of. It doesn't block key commands like copy/paste, select all or arrow keys. But its major disadvantage is
