P. 84

When you enter the value 8, none of the cases will be
                  matched. Hence, the default case will be executed and
                  the output “Invalid day number” will be displayed on the
                  terminal.


                     LOOPING STATEMENTS

                  Looping statements are control flow statements that let us repeatedly run a set of instructions
                  for a specified number of times. These are also known as iteration statements or loops. Java
                  offers three types of looping statements, which are as follows:

                     while
                     do-while
                     for

                  Let us learn about these in detail.
                  The while Loop

                  The while loop is a control statement in Java that repeatedly executes a block of code as long
                  as a specified condition remains true. The loop first evaluates the condition before executing
                  the code inside the loop. If the condition is true, the loop’s body executes, and the condition is
                  checked again after each iteration. This process continues until the condition evaluates to false,
                  at which point the loop terminates and control passes to the statement following the loop.
                  The syntax of the while loop is as follows:

                  while(< conditional expression >)
                                                                                                  Start
                  {
                         [statements]
                         [increment/decrement expression]
                  }
                                                                                               Conditional     False
                  For example,
                                                                                               Expression
                  public class WhileLoop
                  {
                                                                                                      True
                      public static void main(String args[])
                      {
                                                                                          Body of while loop
                          int i = 1;
                          while (i <= 10)
                          {
                              System.out.println("The value of i is: " + i);
                              i++;
                          }                                                                       Stop

                      }
                  }
