Sorry if this is a little abstract. I'm in the early stages of development. I have two object types: An object that needs to store a series of user defined conditions. An object that matches zero or more of the conditions defined in the first object. Here's a simple example of how it would run. A user creates several objects of ty...
Dear all, In Java, we can use variadic function in the following way: public Set packStrings(String...strings){ for (String str : strings){ //Do something on the str } //How to convert strings into a Set? } My question is, what is the type of "strings"? is it String[]? How to put the string(s) denoted by the "st...

I have a POJO class, say Foo, which has a Set of other entity instances, say bars. Also there are standart misc classes for such project: service and dao for both Foo and Bar. I want BarService to get the Set of Bar instances associated with some Foo. Now I have the following code, wich I believe is conceptually bad. public class Foo...

Hi! From J. Bloch A ... source of memory leaks is listeners ... The best way to ensure that callbacks are garbage collected promptly is to store only weak references to them, for instance, by storing them only as keys in a WeakHashMap. So, why there isn't any WeakSet in java collection framework? Thanks. ...
This piece of code generates unexpected output. Hashtable<Pair, Integer> results = new Hashtable<Pair, Integer>(); results.put(new Pair(0, 1), 2); System.out.println("[DBG] " + results.containsKey(new Pair(0, 1))); The output is [DBG] false. Why did Hashtable fail to register this element? Does it have something to do with the way I t...
