800×480 is the most common resolution on Android powered devices. Your aspect ratio would be: 5:3 (which is the same as 800:480 just put in its simplest form). All your graphics should be created on a composition with the size 800×480, not to have stretched graphics when you run your game. I would suggest you … Read more
Based on the conversation in the other answer, it was inferred that the JVM was a 64-bit process. This was confirmed using the pflags command in Solaris. Apparently the -d32 flag passed to the JVM was being ignored. This was due to the possibility of the JVM being a 64-bit one, which was incapable of operating in the 32-bit mode. … Read more
You are facing a connection breakdown. Does this happen in 3G, WiFi or “plain” connection on a computer? Anyway, you must assume that the connection may be lost from time to time, when writing your app. For example, with mobiles, this happens frequently in the tube, in basements, etc. With PC apps, this is less … Read more
A Java class can only extend one parent class. Multiple inheritance (extends) is not allowed. Interfaces are not classes, however, and a class can implement more than one interface. The parent interfaces are declared in a comma-separated list, after the implements keyword. In conclusion, yes, it is possible to do:
Since String IS-A CharSequence, you can pass a String wherever you need a CharSequence, or assign a String to a CharSequence: If you want to convert a CharSequence to a String, just use the toString method that must be implemented by every concrete implementation of CharSequence.
I don’t know about Eclipse’s failures (god knows I’ve pulled enough hair out trying to fix issues my coworker gets using Eclipse), but could you manage with using the [home] character? It’s a kludge compared to \b for your purpose, but if the output you’re using doesn’t work with one control character, try another! 🙂
^^ PS : true = 1 and false = 0
You need to add logic to assign random values to double[] array using randomFill method. Change To Then you can call methods, including list() and print() in main method to generate random double values and print the double[] array in console. One result is as follows:
You’re calling writer.close(); after you’ve done writing to it. Once a stream is closed, it can not be written to again. Usually, the way I go about implementing this is by moving the close out of the write to method. And add a method cleanUp to close the stream. This means that you have the … Read more
It just so happens that I wrote a BigFraction class not too long ago, for Project Euler problems. It keeps a BigInteger numerator and denominator, so it’ll never overflow. But it’ll be a tad slow for a lot of operations that you know will never overflow.. anyway, use it if you want it. I’ve been dying … Read more
