Can someone help me please, I am confused.

Exception in thread "main" java.lang.NumberFormatException: For input string: ""
at java.lang.NumberFormatException.forInputString(Num berFormatException.java:65) this is line 65, /**

at sales.commission.week.pkg4.SalesCommissionWeek4.ma in(SalesCommissionWeek4.java:73)

The String passed to the parseInt() method at line 73 did NOT contain a valid number. The code should either check that the String is not empty and/or it should catch the exception when the String is invalid.

somethong I need to add

Yes, the code should test if there is input before trying to convert it.
