• Clas Dimensions:
  • The constructor needs to provide input validation. Only positive values are allowed for height, width, and depth. If one or more of the parameter values are zero or negative, an IllegalArgumentException should be thrown. We'll introduce exception handling in one of the upcoming modules. For now, just use the code statement provided. throw new IllegalArgumentException("The height, width, and depth of a dimension needs to be positive.");
  • The method toString should return a string of the following format: ({height} x {width} x {depth}) Where {height}, {width}, and {depth} are substituted by the corresponding field values rounded to one digit after the decimal point. E.g., the dimensions 137.81 x 64 x 9.2 return: (137.8 x 64.0 x 9.2)
• Clas Phone
  • The method toString should return a string of the following format: {model} {dimension} Where {model} and {dimention} are substituted by the corresponding field values E.g.: Samsung Galaxy S9 (147.7 x 68.7 x 8.5)
• Clas SmartPhone
  • Analogous to class Dimension, the constructor needs to provide input validation. Only positive values are allowed for the field storage. If there is an attempt to create a new smartphone with an invalid storage value, an IllegalArgumentException should be thrown. This time the error message should be "Storage needs to be assigned a positive value."
  • The method call should return the following string: Calling {number} by selecting the number Where {number} is substituted by the corresponding parameter value. E.g.: Calling 8015817200 by selecting the number
  • The method browse should return the following string: Browsing the web
  • The method takePicture should return one of the following two strings: Taking a horizontal picture or Taking a vertical picture Each time the method is called, one of those two strings should be chosen randomly.
  • The method toString should return a string of the following format: {model} {dimension} {storage}GB Where {model}, {dimension} and {storage} are substituted by the corresponding field values and GB stands for gigabyte. E.g.: Samsung Galaxy S9 (147.7 x 68.7 x 8.5) 64GB
• Enum Voltage Voltage provides three options: V110, V220, and DUAL Those three options correlate to 110 Volt which is used in the US, 220 Volt like in Europe, and the ability to work with both 110 and 220 Volt
• Clas DeskPhone
  • The constructor includes two parameters to initialize the superclass Phone and a third parameter to initialize the field voltage. However, there is no parameter to initialize the field connected. That's because a new DeskPhone out of the box is never connected.
  • The method plugIn sets the field connected to true
  • The method unplug sets the field connected to false
  • The method isConnected returns the value of the corresponding field
  • The method toString should return a string of the following format: {model} {dimension} {voltage} {connectionInfo} Where {model}, {dimension} and {voltage} are substituted by the corresponding field values and {connectionInfo} is one of the following two strings: connected if the desk phone is connected and not connected if it is not connected. E.g.: Crosley CR62-BK (127.0 x 153.0 x 127.0) DUAL connected E.g.: Opis PushMeFon (228.0 x 217.0 x 130.0) V220 not connected
• Clas RotaryPhone
  • The method call should return the following string: Rotating the dial to call {number} Where {number} is substituted by the corresponding parameter value. E.g.: Rotating the dial to call 8015817200
• Clas PushButtonPhone
  • The method call should return the following string: Pushing buttons to call {number} Where {number} is substituted by the corresponding parameter value. E.g.: Pushing buttons to call 8015817200

Testing code:

@Test void isConnected_unplugged_returnFalse() { rotaryPhone.unplug(); assertFalse(rotaryPhone.isConnected()); } @Test void toString_returnsModelDimensionVoltageAndConnectionInfo() { assertEquals("JeKaVis J-P45 (85.0 x 85.0 x 28.0) DUAL not connected", pushButtonPhone.toString()); rotaryPhone.plugIn(); assertEquals("Pyle PRT45 (205.0 x 135.0 x 92.0) V110 connected", rotaryPhone.toString()); }

} I can upload the other testing ones in the comments, not enough space to do it here

Add one more class to the same package. It is called TestClient and it includes the main method.

• Create four variables that store the following objects:
  • A RotaryPhone, model Model 500 with dimensions 143 x 208 x 119 and 110 Volt
  • A PushButtonPhone, model Cortelco 2500 with dimensions 178 x 228 x 127 and the ability to connect both to 110 Volt and 220 Volt
  • A SmartPhone, model Pixel3 with dimensions 145.6 x 68.2 x 7.9 and 128GB storage
  • A SmartPhone, model iPhone8 with dimensions 138.4 x 67.3 x 7.3 and 64GB storage
• Print the title Various Phones: Call the toString methods of all four objects and print the results in separate lines. After that, print a single empty line to group related output.
• Plug in both desk phones. Then randomly select one of the desk phones and unplug it. This selection needs to be done dynamically (at runtime).
• Create an array of type Phone. Add the different phones we created above as elements to the array.
• Print the title Array Elements:
• Loop through all the elements in the array. For each of the array elements do the following:
  • Call the method toString and print it.
  • Make a call to the following number: 8019574111 and print the result
  • If it is a SmartPhone, browse and take a picture. Print the results.
  Print the results of the method calls in separate lines followed by an empty line to group related output.
