Question 37

Examine this statement which is submitted for compilation:

Which three are true? (Choose three.)

This is a PACKAGE specification. A PACKAGE BODY is needed to use this.

This will not compile successfully because the loan_amount variable is declared NOT NULL but lacks an initialization assignment.

This program unit will compile successfully.

Initialization of min_bal can be done while using this packaged constant in another program.

Initialization of loan_amount can be done while using this packaged variable in another program.

This will not compile successfully because the min_bal constant must be initialized.

This is BODILESS PACKAGE. A PACKAGE BODY is not required to use this.

Correct Answer: B, F, G

This package specification contains some errors. The variable 'loan_amount' is declared as NOT NULL but lacks an initial value, which is required for compilation, so it will not compile successfully because of this issue. Additionally, the constant 'min_bal' must be initialized upon declaration, which is not done here, causing another compilation error. Therefore, the correct statements are that this package will not compile successfully and both 'loan_amount' and 'min_bal' need initialization. Lastly, this is a bodiless package, so a package body is not required to use it.

Es correcto las constantes o variables no tiene porque inicializarse solo desde otros paquetes. Si es obligatorio que sean inicializadas si son cosntantes o si son variables not null
