Assignment

Create a class named Module3 containing the following data members and methods (note that all data members and methods are for objects unless specified as being for the entire class)

1) Data members:

a. A Scanner object named reader (your class will need to import the Scanner class)

b. Two int variables named format and pointIndex

c. A double variable named inputDouble

d. A String object named outputString, initialized to "" (an empty String)

2) Methods:

a. A main method that, in order:

Creates a new Module3 object

Prints the text starting application to the console

Calls method b) with the argument "Please enter a floating point number" and assigns its returned double value to inputDouble

Calls method c) with the argument "How many decimal places to display?" and assigns its returned int value to format

Calls method d) with the argument format and the String "The formatted number is: "

Prints the text ending application to the console

b. A method named getInput that accepts a String parameter, prints the parameter String to the console, accepts a user-entered double via the console (use Scanner.nextDouble()), prints "Thank you" to the console, and returns the user-entered double value.

c. A method named getFormat that accepts a String parameter, prints the parameter String to the console, accepts a user-entered int via the console (use Scanner.nextInt()), prints "Thank you" to the console, and returns the user-entered int value. For error-checking, if the user enters a negative value, the program should print the message "invalid input. halting." to the console, then exit the program by calling System.exit(1);

d. A method named convert that:

Accepts two parameters: a String parameterand an int named places

Assigns outputString the text "" + inputDouble

Assigns to pointIndex the index of the decimal point (use String.indexOf())

If places is greater than 0, places should be incremented by one (to account for the decimal points extra character)

Extracts the substring from outputString starting from index zero to the specified number of decimal places (i.e., pointIndex + places)

Displays via the console the parameter Stringconcatenated with the substring from the previous bullet point

Additional Constraints

The program should be implemented as a single file holding the public class Module3. Comments should be provided at the start of the class file (i.e., above the class definition) giving the class authors name and the date the program was finished.
