APFIVE Significance Of Int Data Type
Which statement best describes the significance of using an int variable for ‘balance’ in this program?
Imagine a banking transaction system where account balances are updated after deposits and withdrawals. The system uses variables of a consistent type to ensure accurate arithmetic operations.
A
Java enforces that the type of a variable remains constant, ensuring type safety and consistent behavior during reassignment.
B
Using an int variable significantly improves runtime performance compared to other numeric types.
C
The variable ‘balance’ cannot be updated, thus requiring a new variable for every change.
D
Java will automatically convert any new value to a double if needed, making type specification unnecessary.
