The quiz (given onscreen) is provided here, along with the solutions:
1. (12 pts.) Circle all of the following that are true:
  1. An MP3 file is an example of a binary file.
    TRUE, an MP3 file is a good example of a binary (non-text) file.
  2. A .java file is an example of a binary file.
    FALSE. If you can open it and read it in a text editor (like vim), it's a text file.
  3. A .class file is an example of a binary file.
    TRUE, it's a compile, binary file that you can't read in a text editor.
  4. Using an ObjectOutputStream, you can write an entire array of objects with a single call to writeObject.
    TRUE. As long as the objects in the array are serializable, writeObject will write the array and all the objects in the array.
  5. In order to write an object of a class Foo to an ObjectOutputStream, the class Foo must be declared with implements Serializable.
    TRUE. That's exactly what you do.
  6. When you read from a RandomAccessFile, you don't know which bytes you're getting, because they're read from random locations in the file.
    FALSE. A RandomAccessFIle allows you to move around inside the file before reading or writing. But, you know where you are when you read/write.
2. (12 pts.) Circle all of the following that are true:
  1. A layout manager is responsible for adjusting the layout (size and positions) of the components in a container.
    TRUE. That's a layout manager's job.
  2. A container can contain more than one component.
    TRUE.
  3. All layout manager require that a location (NORTH, SOUTH, EAST, WEST, or CENTER) be specified when adding a component to a container.
    FALSE. Only BorderLayouts require a location
  4. To add a component to a container, use the following code: component.addToContainer(container);
    FALSE
  5. To add a component to a container, use the following code: ntainer.add(component);
    TRUE
  6. A JButton is an example of a component.
    True
