| + | Introducing students to roles of objects and variables is difficult. Need to distinguish: | ||
| + | * Variables come in two types. Basic types and object types. | ||
| + | * Basic types actually hold the data: integers, characters, doubles, booleans. | ||
| + | * Object types do not hold objects in them. Objects themselves are stored elsewhere, and the variable simply has their address. | ||
| + | * The actual objects know their classes. | ||
| + | * When you do 'String s = new String("abc");', these things happen: | ||
| + | * a piece of memory is picked (for s) | ||
| + | * new picks a part of memory the right size for your String object | ||
| + | * String() is the constructor, and puts your values into the object | ||
| + | * new returns the address of that part of memory | ||
| + | * the address is stored into s. | ||
