Can you please help me to solve this java program

Create an Eclipse Project called javaProgram. Create a class called CheckedVUncheckedExceptions. In this class create two methods. Create a static method called capitalizeString(String s) to convert a String that's passed to ALL CAPS. The capitalizeString method must be declared to throw a NullPointerException. Create a second static method called openFile(String fileName) which will accept the name of a file and attempt to test whether the file exists [File file = new File(fileName); use file.exists ( to test file existence]. The openFile method must be declared to throw IOException. Now call both methods from the main method (note: you will be forced by the compiler to place a try and catch around one the methods you have written due to it being a checked exception). Required activities and marking guideline: - Implement capitalizeString method - Declare capitalizeString method to throw NullPointerException - Implement openFile method - Declare openFile method to throw IOException - Call both methods from the main - Add necessary try catch to method calls in main - Add comments to your code explain why one of the methods called in the main required a try block (or throw) and the other method did not (use regular Java comments in the code
