\b;Instruction \c;new\n; (for specialists)
|
||
|
|
The \c;new\n; operator creates a \l;class\u cbot\class; instance:
|
||
|
|
\c;\s; MyClass item; // now item is a null reference
|
||
|
|
\s; item = new MyClass(); // now item is a reference
|
||
|
|
\s; // to a new class instance
|
||
|
|
\n;
|
||
|
|
If you want to create a new instance at declaration time you can ommit the new \c;new\n; operator by putting () after the declaration:
|
||
|
|
|
||
|
|
Instead of:
|
||
|
|
\c;\s; MyClass item = new MyClass();
|
||
|
|
\n;you can write:
|
||
|
|
\c;\s; MyClass item();
|
||
|
|
\n;
|
||
|
|
If your class has a constructor with parameters you can write:
|
||
|
|
\c;\s; MyClass item = new MyClass(2, 3);
|
||
|
|
\n;or:
|
||
|
|
\c;\s; MyClass item(2, 3);
|
||
|
|
\n;
