beginner to Java

Good evening,

I am taking a class in Java, and need help answering the following 2
questions. Any help will be greatly appreciated.

Question 6: I can't make ends meet with this question. I have read the
chapter back and forth, but i don't understand where to dissect the
question.

 public class ScopeRules // line 1
{
      static final double rate=10.50;
      static int z;
      static double t;

      public static void main(String[]args) // line 7
      {
            int num;
            double x, z;
            char ch;
            // main block...
      }

      public static void one(int f, char g) // line 15
      {
            // block one...
      }

      public static int w; // line 20

      public static void two(int one,int i) // line 22
      {
            char ch;
            int a;

            //block three
            {
                  int x = 12; // line 29
                  //...
            }//end block three
            // block two... // line 32
      }
}

Which of the following identifiers is visible in method one? rate
(before main)
         local variables of method two
         x (block three's local variable)
         one (method two's formal parameter)

 _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _
_ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _

Question 17

I don't understand what the term "S" is suppose to define. If lastinitial
is suppose to be S, than would it default to Section 5, since S is not a
case study. Please clarify.

 switch(lastInitial)
{
case 'A': System.out.println("section 1");
            break;
case 'B': System.out.println("section 2");
            break;
case 'C': System.out.println("section 3");
            break;
case 'D': System.out.println("section 4");
            break;
default: System.out.println("section 5");
}

Based on the code above, what is the output if lastInitial = 'S'?
         section 2
         section 3
         section 4
         section 5

Thanx again.

Alvin
