When I want to increase the infected location, the following error exists and is not handled.

Enter the infected PatientID that you want to add the location visited for: 
!@#!@##!@%#@%#@$@#$#@$@#$#@@@@@@@@@@@@@@$@#$#@$@#C#CECERCE
java.lang.NumberFormatException: For input string: "!@#!@##!@%#@%#@$@#$#@$@#$#@@@@@@@@@@@@@@$@#$#@$@#C#CECERCE"
Please enter command: ["c", "sn", "sp", "i", "slv", "cs", "d", "x", "undo", "redo"]
c = create Patient, sn = show latest infection report, sp = show patient, i = increase location of infection spreading, slv = search different level of infection location, cs= change patient's health status, d = display undo/redo list, x = exit system, u = undo, r = redo
