Significance Of Int Data Type
In a banking program, a variable balance is declared as an int to store account balances. Which statement best describes a consequence of declaring the variable with the int data type?
A
The variable ‘balance’ cannot be updated, thus requiring a new variable for every change.
B
Java will automatically convert any new value to a double if needed, making type specification unnecessary.
C
Using an int variable significantly improves runtime performance compared to other numeric types.
D
Java enforces that the type of a variable remains constant, ensuring type safety and consistent behavior during reassignment.
