Answer 1

Class colorClass = Color.class; // 1
Field field = colorClass.getDeclaredField(command); // 2
Color color = (Color)field.get(Color.WHITE); // 31) Foo.class refers to the Class object that represents class Foo. See the API for java.lang.Class for more info about a Class object.
2) See the API for java.lang.reflect.Field. This is part of the reflection API, that lets you find out stuff about classes, fields, methods at runtime.
3) Ditto--part of java.lang.reflect.Field.
