The program below display the following menu:Geometry Calculator1. Calculate the Area of a Circle2. Calculate the Area of a Rectangle3. Calculate the Area of a Triangle4. Quit
Enter your choice (1-4):If the user enters 1, the program should ask for the radius of the circle and then display its area. Use 3.14159 for . If the user enters 2, the program should ask for the length and width of the rectangle, and then display the rectangle’s area. If the user enters 3, the pro- gram should ask for the length of the triangle’s base and its height, and then display its area. If the user enters 4, the program should end.
Input Validation: Display an error message if the user enters a number outside the range of 1 through 4 when selecting an item from the menu. Do not accept negative values for the circle’s radius, the rectangle’s length or width, or the triangle’s base or height.

create a JAVA PROGRAM as a Currency Converter program. The program performs Currency Exchange operation between Saudi Riyals R, Dollars $, Euro € and British Pounds £.
The program firstly shows a menu to the user which allows the user to choose one of the possible currency exchange operations and the last option in the menu should allow the user to end the program (see figure1).
The menu should be like as figure 1.
If the user enters a wrong choice, an error message should appear and the program asks the user to re-enter a correct number.
When the user selects an operation, the program do the following:
Prompt user to enter the amount to be changed
Input amount
Calculate and print the result.
Once the user presses any key, the menu appears again and the user can choose a new operation.
