rogram requires 2 java files, the testing program should use a switch

The switch statement allows us to execute a block of code among many alternatives.

switch (expression) {
  case value1:
    // code to be executed if
    // expression is equal to value1
    break;
  
  case value2:
    // code to be executed if
    // expression is equal to value2
    break;
  
  ...
  ...
  
  default:
    // default statements
  }

The expression is evaluated once and compared with the values of each case label.

• If there is a match, the corresponding code after the matching case label is executed.
  
  For example, if the value of the expression is equal to value2, the code after case value2: is executed.
• If there is no match, the code after default: is executed.

Note: We can do the same functionality using the Java if...else...if ladder. However, the syntax of the switch statement is cleaner and much easier to read and write.
