I am using JPanel in the front end, and I want to add scrollbar in Jpanel.

The exception text is quite clear: you're trying to interpret some text as a number in line 247 of your MedicleDemo class. Your last sentence is unconnected with the exception and unanswerable as is. — Mat

From the exception what i understand is you are converting String to Integer using parseInt so the string must contains only numeric but you are passing "sdfsf" so it is throwing NumberFormatException

It's because the string you are attempting to pass sdfsf it's not having the appropriate number format. Look at the javadoc of the exception
