EX 5.7 What output is produced by the following code fragment?

int num = 0, max = 20;
while (num < max)
{
System.out.println (num);
num += 4;
}

EX 5.8 What output is produced by the following code fragment?

int num = 1, max = 20;
while (num < max)
{
if (num%2 == 0)
System.out.println (num);
num++;
}

EX 5.9 What is wrong with the following code fragment? What are three

distinct ways it could be changed to remove the flaw?

count = 50;
while (count >= 0)
{
System.out.println (count);
count = count + 1;
}

EX 5.10 Write a while loop that verifies that the user enters a positive
integer value.
EX 5.11 Write a code fragment that reads and prints integer values
entered by a user until a particular sentinel value (stored in
SENTINEL ) is entered. Do not print the sentinel value.
EX 5.12 Write a method called maxOfTwo that accepts two integer param-
eters and returns the larger of the two.
EX 5.13 Write a method called larger that accepts two floating point
parameters (of type double ) and returns true if the first param-
eter is greater than the second, and false otherwise.
