I’ve been playing with this also (used LinearLayout) but at the end I had lot of problems with memory consumption (especially when I had to reload the items). I settled on simple solution which uses two synchronized ListViews. This way I can exploit internal caching which helps a lot. To do this I had to …
There are already a bunch of answers here, but I would really like to dive into some details (as much as my knowledge let’s me). I will strongly advise you to run each sample that is present here in the answer to see for yourself how things are happening and why. To understand the solution, …
For different types of JDKs or installations, you will have different paths. On Mac OS X Mavericks, the path I found as following: 1) Built-in JRE default: /Library/Internet\ Plug-Ins/JavaAppletPlugin.plugin/Contents/Home 2) JDKs downloaded from Apple: /System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home/ 3) JDKs downloaded from Oracle: /Library/Java/JavaVirtualMachines/jdk1.8.0_11.jdk/Contents/Home
Section 3.3 of the CDI specification gives a pretty good high level overview of the use of the @Produces annotation: A producer method acts as a source of objects to be injected, where: • the objects to be injected are not required to be instances of beans, or • the concrete type of the objects …
No, you can’t. But what’s the point of this over an if-else statement? Are you really trying to save 7 characters? if (name.isChecked()) { name.setChecked(true); } else { name.setChecked(false); } or if you prefer bad style: if (name.isChecked()) name.setChecked(true); else name.setChecked(false); Never mind the fact that you can just do (in this case): name.setChecked(name.isChecked()); The …
Currently (last tested on Java 17) it is possible to do it with split(), but in real world don’t use this approach since it looks like it is based on bug since look-behind in Java should have obvious maximum length, but this solution uses \w+ which doesn’t respect this limitation and somehow still works – …
For those whose problem has not been solved; try this solution: Set the global environment variable “J2D_D3D” to “false” inside the OS. According to Sun, this setting is used to turn off the Java 2D system’s use of Direct3D in Java 1.4.1_02 and later. ie: simply create a environmental variable with name “J2D_D3D” and value …
This can be achieved by using the built-in inspection Java | Declaration redundancy | Unused declaration. To run it on whole project go to Code -> Analyze -> Run inspection by name…, type Unused declaration and select desired scope. Then carefully check output and mark some classes as entry points if needed. Now you can …
I’m assuming you’re referring to the /WEB-INF directory in the root of the web application folder structure. No, it’s not in the classpath. /WEB-INF/classes is on the classpath though, and so are the JAR files in /WEB-INF/lib.
There are two main reasons you might want to mark an argument final. First, if you’re planning on using the argument in an anonymous inner class, then you must mark it final so that it can be referenced in that class. This is actually a pretty common use case for marking arguments final. The other …
