String [] info1={" zhang ", "Rmb", "8888.00 Rmb", "18888.88 Rmb"};
Miami
Miami
Bank showBookInfo ();
Bank1. ShowBookInfo1 ();
}
}
This is after I wrote, the error
The name of the bank time deposit account currency deposit account balance
The Exception in the thread "main" Java. Lang. NullPointerException
The at GenericProgramma. Miami. ShowBookInfo (Arbitrarily. Java: 21)
The at GenericProgramma. Miami. The main (Arbitrarily. Java: 40)
This is what reason!
