Instructions

Use separate methods for Part A and Part B.

Part A

Prompt the user for the number of cents 0-99. Assume that the user will enter an integer. Use a method for validating the input. If the input value is not valiid: is less than 0 or greater than 99, then prompt the user to enter a valid number 0-99.

Use if/else-if/else for this part. Use logical operators && and || (AND and OR) as needed If the user enters invalid input 2 times, tell the user "They have exceeded the number of tries. Goodbye" and end the program.

When the user enters a valid input, calculate the change and display the results. Example calculation for Quarters:

cents=in.nextInt();

setQuarters(cents/25);

cents =cents % 25; // get the remaining cents for calculating dimes

Part B

Prompt the user for the number for a day 1-7. Assume that the user will enter an integer. Use SWITCH statements to evaluate the day of the week - DO NOT use if-else statements. Example:

switch(dayNumber){

case 1:

System.out.println("Monday");

break;

//type your code for case 2 to case 7

default:

System.out.println("Invalid day");

} //end switch

Part C

Use either the switch or the if-else statement to call the methods that execute both Part A and Part B.
