Question

Need in java programming

Answer 1

Read a line of input as String and then split by delimiter (space, comma etc. you decide)

Then use parse*** method from appropriate wrapper class(Integer ,Float etc. as per your requirement)

Rest of the things are easy. At least try to do and show code if you need help.
