Answer 1

MyClass[] myclasses = new MyClass[10];
// or
MyClass myclasses[];
myclasses = new MyClass[10];
// or
MyClass myclasses[] = new MyClass[20];
// etcOf course, this just allocates the array. Each position in the array is initially set to null. If you want to allocate the objects themselves, just allocate each instance in a loop.
