First question carries 5 marks and second question carries 10 marks.

1. Create a class called Invoice that a hardware store might use to represent an invoice for an item sold at the store. An Invoice should include four pieces of information as instance variables‐a part number(type String),a part description(type String),a quantity of the item being purchased (type int) and a price per item (double). 
1. Your class should have a constructor that initializes the four instance variables. Provide a set and a get method for each instance variable. 
2. In addition, provide a method named getInvoiceAmount that calculates the invoice amount (i.e., multiplies the quantity by the price per item), then returns the amount as a double value. 
3. If the quantity is not positive, it should be set to 0. If the price per item is not positive, it should be set to 0.0. 
4. Write a test application named InvoiceTest that demonstrates class Invoice’s capabilities.
2. Write a Java applet program that works as a simple calculator. Use a grid layout to arrange buttons for the digits and for the + – * % operations. Add a text field to display the result. The output should look as the following screenshot.

a)Write a temperature conversion applet that converts from Fahrenheit to Celsius. The Fahrenheit temperature should be entered from the keyboard (via a TextField). A Label should be used to display the converted temperature. Use the following formula for the conversion:

Celcius = ((5/9)*(Ferenheit‐32)).

more challenge ..

b.) Enhance the temperature conversion applet by adding the Kelvin temperature scale. The applet should also allow the user to make conversions between any two scales. Use the following formula for the conversion between Kelvin and Celsius : 

Kelvin = Celcius + 273.15

AN IDEAL OUTPUT SHOULD LOOK LIKE THIS

Note : You may use Java SWING objects as well to accomplish the task.

Write a program to find missing numbers in an  array

/*

To find missing numbers in an array first we need to make sure that array is sorted.

After sorting we need to check that array each element with next element then we can find the difference.

if Array is not sorted :To sort array use Arrays.sort(array);

If difference is 1 then no need to do any thing because numbers are in order.

If difference is not equal to 1 then we need to print all those numbers or pick those numbers and place it in one array.

this would be the logic to find missing numbers in an array

Here there may be a chance of array not starting with 1. then we need to check first itself whether array starts with 1 or not if not we need to print 1 to starting element of array.

for example int a[]={4,5,6,8}; then we need to print 1 2 3  7.
