Hey Guys I am Developing an Android App to Show Local Bus Schedule. And I get a little trouble in executing specific queries.
The Below SQL query Works well in sqlite browser as i want
* pnotocdm is the table name
* time is column name
* time('now','localtime') is the function to get current time in local time format.
However when i convert this sql query to Java rawquery() it does not return the result i want. Any help ?
PS- I stored time column values with only hour and minutes.

Code:
SELECT * FROM pnotocdm WHERE time > time('now','localtime') LIMIT 4;* time is column name
* time('now','localtime') is the function to get current time in local time format.
However when i convert this sql query to Java rawquery() it does not return the result i want. Any help ?

^^ Try this :
String s = "12:18:00";
DateFormat f1 = new SimpleDateFormat("hh:mm:ss");
Date d = f1.parse(s);
DateFormat f2 = new SimpleDateFormat("h:mma");
f2.format(d).toLowerCase();
String s = "12:18:00";
DateFormat f1 = new SimpleDateFormat("hh:mm:ss");
Date d = f1.parse(s);
DateFormat f2 = new SimpleDateFormat("h:mma");
f2.format(d).toLowerCase();

To create GUI in Java you either need to use AWT or Swing. As Swing is derived from AWT and contains much more features, you should use that instead. You can either parametrically create GUI or use NetBeans' quick GUI builder.

Started Android Programming, and was going through a few example codes, and making some of my own.
In this i'm trying to display the analog clock showing the current time with a toggle button.
Getting this error in MainActivity... (marked with #)
MainActivity.java
activity_main.xml
Again, pretty much new to Android programming. Let me know if something wrong with the code or any changes.

I have installed the jdk1.8.0_11 I also get the verification that the software is installed successfully. I am using the book "CORE JAVA Volume 1 - Fundamentals" 9th edition written by Cay S. Horstmann, Gary Cornell. In this book they have said to make a directory by using the command "mkdir src". Every thing is fine uptil C:\Program Files\Java\jdk1.8.0_11\bin But after this when I use the command "mkdir src" I get the following error "Access Denied". I have set the path correctly. Please help. I am sorry if I have posted the question in the wrong thread. But I am new to programming. Thank you

This problem is not related to Java, rather to permission settings. You need Admin provilages to modify the files and folders in certain locations like C:\Program Files, C:\Windows, etc. When you ran the command you were most probably in C:\program Files and you were working on a non-elevated command prompt (cmd run without admin privileges) which gave the error on trying to create a new dir there.
I'd recommend creating your Java source files in some other locations like Documents. Or if you necessarily need to create dir in that path then run cmd with admin rights by right clicking on it and choosing "Run as Administrator".

Get Eclipse Luna, it takes 5 mins to setup, and then code away, luna supports java 8. Also if you need to learn J2EE, just get TomEE. Coding via notepad is not a a very good way at all, you need to debug your code, see the console, use an IDE.
Also note, if you are new to JAVA altogether please get this book, this is the best book to learn JAVA: SCJP Sun Certified Programmer for Java 6 Study Exam 310-065 Guide (With CD-ROM) (English) 1st Edition - Buy SCJP Sun Certified Programmer for Java 6 Study Exam 310-065 Guide (With CD-ROM) (English) 1st Edition by Sierra, Kathy|Author; Bates, Bert|Aut

On a side note: Can anyone suggest me some good resources or books to learn Java 8(only new features), specially the lambda functions.

If these websites allow only the compilation, then I'd like to suggest koding.com
It gives you a VM, and you can install whichever compiler you like, save the code, resume from anywhere. It used to be bad, but when I used it recently, I found it delighting.
