If you use Lombok (1.18.22 in my case) and the error message in Eclipse Error Logs says Unhandled event loop exception, then it might be a Lombok issue – which in the mean time has been resolved. Upgrade Lombok to 1.18.24 or above.
Shortest Version I could came up with: if (!($value = Read-Host “Value [$default]”)) { $value = $default } This version doesn’t have to use else.

Why does Visual Studio by default create a private static method when refactoring code and selecting extract method? It does this only if your method doesn’t access any member variables/methods/properties. This is good because it basically operates on the principle of least assumptions: since you don’t access instance-specific data, might as well make the method … Read more

Sometimes there are too many local variables to keep track of, or too many if/for statements. In all cases it makes it harder to understand what the code is supposed to … Read more

Even the code folding just matches up opposing braces. To do a proper refactoring, you have … Read more
One reason it looks like a lot of code is that it is very repetitive. Use variables to store the parts that are repeated, and that will help with the readability: private List<Foo> parseResponse(Response<ByteString> response) { Status status = response.status(); int code = status.code(); boolean payloadAbsent = !response.payload().isPresent(); if (code != Status.OK.code() || payloadAbsent) { … Read more
You can use Runnable objects: public static void someMethod(boolean flag, Runnable block1, Runnable block2) { //some other code if(flag) block1.run(); else block2.run(); //some other code } Then you can call it with: Runnable r1 = new Runnable() { @Override public void run() { . . . } }; Runnable r2 = . . . someMethod(flag, … Read more

(source: eclipse.org) You can then rename the com package and check the Rename subpackages option to … Read more
