Java: ignore warnings from generated code Again, I'm playing around with `javaCC`, and get those annoying warnings about "unused" and "dead code". Is there a decent way to put a `@SuppressWarnings` annotation on a whole package but not on the whole project or workspace? (more) |

eclipse: change toString to prettyPrint The task looks ridiculously simple, but I could not find a way of doing it but manually. I have a class with a `@Override ... toString()` method. I want to diversify this to a more specialized method that takes parameters to specify what should show up. Eclipse failed to simply rename ... (more) |

eclipse templates -- creating and setting a permanent variable In eclipse (java) Window->Preferences->Java->New new templates can be created. In the field "Pattern" I entered ``` System.out.println("DEBUG ${label}"); ${cursor} ``` I like old-style debugging, so I use a lot statements like `System.out.println("DEBUG A");` ... `System.out.println("...

java.time.ZonedDateTime missing seconds in output When printing a `java.time.ZonedDateTime`, it's missing the seconds in output, is it a bug or a feature?

The solution with varargs looks interesting, I wasn't thinking of that. I had thought of the first alternative, but passing an instance instead of a class-object.

This code doesn't compile: ```java package tryNcry; public class ExampleClass { S[] createArray(int n) { return new S[n]; // obvious compile time ERROR here: // Cannot create a generic array of S } } ``` The reason for this is obvious: due t...

"When you give code a type, you are typing the variable, not the value."

Trouble understanding java lambdas and generics Of course, everyone thinks to understand lambdas and generics. I was one of those until recently.
