I’m wondering if there’s a way to have tabs convert to spaces in a jeditorpane, much like you’d see when working in an IDE. I don’t want to set the tab size. I can already do that easily. I want to have tabs replaced with their equivalent in spaces. So for example if my tabs are 5 spaces long, I
Circle approximations using Bezier curves
I have 2 questions about bezier curves, and using them to approximate portions of circles. Given the unit circle arc (1,0)->(cos(a),sin(a)) where 0 < a < pi/2, will it result in a good approximation of this arc to find the bezier curve’s control points p1, p2 by solving the equations imposed by the requirements B(1/3) = (cos(a/3), sin(a/3)) and B(2/3)
How to check whether the file is binary?
I wrote the following method to see whether particular file contains ASCII text characters only or control characters in addition to that. Could you glance at this code, suggest improvements and point out oversights? The logic is as follows: “If first 500 bytes of a file contain 5 or more Control characters – report it as binary file” thank you.
Specifying an order to junit 4 tests at the Method level (not class level)
I know this is bad practice, but it needs to be done, or I’ll need to switch to testng. Is there a way, similar to JUnit 3’s testSuite, to specify the order of the tests to be run in a class? Answer If you’re sure you really want to do this: There may be a better way, but this is
Coding Conventions – Naming Enums
Is there a convention for naming enumerations in Java? My preference is that an enum is a type. So, for instance, you have an enum I am opposed to naming it: I understand it is easy to pick off which files are enums, but then you would also have: Also, is there a good document describing the same for constants,
JSF 1.0 vs JSF 2.0
What is difference between these 2 version of JSF (JSF 1.0 and JSF 2.0)? As I am new to java, I only find that difference is at Architectural level. But, in perspective, I can’t get how much it affects the application development ? Also, the MVC imposed is different with JSF and Spring. Even if JSF has improved architecture, still

GPS Time Representation library
I am looking for a Java library that handles conversion to/from GPS Time. GPS Time has an epoch of 6 January 1980, and does not have leap seconds, so it differs from the more standard time representations. Here is the relevant description from wikipedia: While most clocks are synchronized to Coordinated Universal Time (UTC), the atomic clocks on the satellites
In Java, is there a way to write a string literal without having to escape quotes?
Say you have a String literal with a lot of quotation marks inside it. You could escape them all, but it’s a pain, and difficult to read. In some languages, you can just do this: In Java, however, ” is used for chars, so you can’t use it for Strings this way. Some languages have syntax to work around this.
