Hello all,
When I run the application, it requires to enter Employee number, social, and name. I can enter any letter and number to call employee number, social and name. I do not know how to validate letters and number.
For example, for the employee number, I have to enter number only;
for employee name, I have to enter letter only,
Please give some idea.
Thanks

Better write a separate class for all the validations and put the validNumber, validString e.t.c methods in there.
For the validations itself you can use exception handling for numbers. Just open the specs for the Integer class and look at the parseInt method. An exception is thrown if the input is not a valid int. Also check out regular expressions.
