Weak Reference Objects are not the default type/class of Reference Object and to be used they should be explicitly specified like in the above example. This kind of reference makes the reference object eligible for GC. That is, in case the only reference reachable for the StringBuilder object ...
One area likely to cause confusion for those coming from a Java or VB6 background is the distinction between value types and reference types in C#.In particular, C# provides two types—class and struct, which are almost the same except that one is a reference type while the other is a va...
In other words, we can say about value (or instance, interchangeably) of value type or reference type. Going further, those are defined as: “type, value: A type such that an instance of it directly contains all its data. (…) The values described by a value type are self-contained....
Value type vs reference type usingSystem;classProgram {staticvoidMain(string[] args) {inti = 5;intj = i; i = 3; Console.WriteLine("i="+ i); Console.WriteLine("j="+ j); } } i=3 j=5 From the outputs we can see that the value ofjdoesn't change even the value ofiis changed...
The preference order is the order in which providers are searched for requested services when no specific provider is requested.To use the JCA, an application simply requests a particular type of object (such as a MessageDigest) and a particular algorithm or service (such as the "SHA-256" ...
