Create an application named Numbers whose main() method holds two integer variables. Assign values to the variables. Pass both variables to methods named sum () and difference(). Create the methods sum() and difference(); they compute the sum of and difference between the values of two arguments, respectively. Each method should perform the appropriate computation and display the results. Save the application as Numbers.cs

After the user has selected the desired options, replace the message in the text area so it displays a running list of the user’s choices.
Write an application that plays “guess the number” as follows: Your application chooses the number to be guessed by selecting an integer at random in the range 1–10. The application then displays the following in a label:I have a number between 1 and 10. Can you guess my number?Please enter your first guess. A JTextField should be used to input the guess. As each guess is input A JLabel should display either "Too High" or "Too Low" to help the user zero in on the correct answer. When the user gets the correct answer, "Correct!" should be displayed, and the JTextField used for input should be changed to be uneditable. A JButton should be provided to allow the user to play the game again. When the JButton is clicked, a new random number should be generated and the input JTextField changed to be editable.
