In Java, C#, and VB .NET, the constructor creates reference type objects in a special memory structure called the
"[[heap (data structure)|heap]] for reference types". Value types (such as int, double, etc.), are created in a sequential structure called the "[[stack (abstract data type)|stack]]".
VB .NET and C# also allow the use of the ''new'' operator to create value type objects, ofbut these value types.type However,objects inare thosecreated languageson eventhe usestack regardless of newwhether forthe valueoperator typesis createsused objectsor onlynot. on stack.
In C++, objects are created on the stack when the constructor is invoked without the new theoperator, objects areand created on stackthe heap when the constructor is invoked with the new operator.
