1. Identify the constants in these statements -

final int NUMBER_CASES = 10; int x =10; final int PI = 3.14159; double num = 12.0; final int RATE = 1.5;

2. Modify the following code so that the displayAddress() method is called instead of the three println() statements.

Code:

public class Method1{

public static void main (String [] args){

System.out.println("HCC"); System.out.println("551 24th Street"); System.out.println("Ruskin, FL 33570");

} }

3. Write code that takes three numbers entered from the keyboard and calculates the average. Use the method calculateAvg().
