java - Stupid Math issue -


Look at the gray circles with lines, they should be kept equally to represent hours, here is their code , where did I go wrong? (Int i = 0; i & lt; 12; i ++) {c.drawCircle (140 * (float) Math.cos ((double) (i * 30) 

 for  ) + Width / 2, 140 * (float) math.Syn ((double * (i * 30)) + height / 2, 1, p); }

enter image details here

The angle must be provided in radians ( 0 and 2 * Math.PI ).

Then, use 

  Math.cos ((double) (i * 30))

instead of 

  Math.cos (i * Math.PI / 6.0)

Note that I also repeated the waste cast: one int multiplication and one double first Produces a double from itself.

java - NullPointerException for a 2d Array -

नक्शा = नया बफर्ड इमेज [चौड़ाई] [ऊंचाई]; के लिए (int i = 0; i & lt; height; i ++) {for (int j = 0; j & lt; चौड़ाई; j ++) {if (charMap [j] [i] == पर्वत। इंडेंटफार्म) {if (j + 1 & lt ; चौड़ाई और amp; amp; j-1 & gt; = 0) {if (charMap [j-1] [i]! = पर्वत। इंडेंटिफ़ायर & amp; amp; & amp; amp; charMap [j + 1] [i]! = पर्वत। इंडेंटफार्म) {नक्शा [जे] [आई] = टाइल ग्रिड [1] [10]; }} और {नक्शा [जे] [आई] = टाइल ग्रिड [8] [10]; }}} यह कोड है जिसे मैं सेल के चारों ओर प्रत्येक टाइल को चेक करके 2 डी सर की जांच करने के लिए उपयोग कर रहा हूं लेकिन मुझे लगता है कि किसी को भी सोच रहा हूँ मदद कर सकता है? मुझे संदेह है कि आपको NullPointerException को charMap [j] से प्राप्त हो रहा है [ I] == पर्वत। इंडेंटिफ़ायर लाइन। सुनिश्चित करें कि आप ज्योफ द्वारा सुझाए गए दोनों मानचित्रों के लिए आंतरिक सरणियों को प्रारंभ करते हैं।

python - Assemble mpeg file unable to play in mediaplayer -

I am currently working on a school project and I think that is to gather some problems with the MPEG file I The scope of my project is: 1) Split the MPEG file into pieces of many fixed sizes. 2) Collecting some of them and leaving some part. Problem 1: When I run the file in the media player, it will play the video until it reaches that segment which I left Give it Example: Chunk = ["yui_1", "yui_2", "yui_3", "yui_5", "yui_6"] Duration of each segment: 1 second * If you think I have left the "yui_4" section. * If I went to collect all the parts except "yui_4", then the video will play the first 2 seconds before being hanged throughout the period. Problem 2: When I gather the first part off the part, it is unable to run the full MPEG file is. Duration of each piece: 1 second Example: wheel = ["yui_2", "yui_3", "yui_4", "yui_5", "yui_6"...
