• Write a method to do X (practice next lecture).
• Write a code segment to do X (practice next lecture).
• Design a class with the following properties....
• Instantiate objects of a specified class and use them to solve a problem.
• Trace the following code segment (emphasis on segments with loops and arrays).
• Draw a picture of the variables and objects after the following code is executed (emphasis on references to arrays, arrays, arrays of objects).
• Using short-circuit evaluation (flow chart the logic; rewrite a nested if using short-circuit evaluation).
• Answer questions about scope and parameter passing.
• You must know the binary and linear search algorithms.

• Scope of variables restricted to block in which they are defined (from the point of definition on).
• Can't have nested scope in methods.
• Parameter's scope is the method.
• Good practice to give variables smallest scope possible.
• Give a couple of examples of test problems.

    if (myDispenseWater.getBottles() && myMoney.takeMoney() 
                                     && myDispenseWater.dispense() ) 
        System.out.println("Drink dispensed");
    else 
        System.out.println("Sorry");

Textbook examples 5.18 and 5.19 on pages 218-219 also illustrate this.
