Question

The program has a compilation error because s is not initialized, but it is referenced in the println statement. The program has a runtime error because s is not initialized, but it is referenced in the println statement. The program has a runtime error because s is null in the println statement. The program compiles and runs fine.

Answer 1

Answer:

The program compiles y runs fine

Explanation:

Remember the following:

1. the reserved word “null” indicates that a variable that refers to an object is “without object”,

2. The variable has been declared but does not point to any object.

3. This may be because it was not initialized by assigning an object through the new instruction,

4. or that by mistake the reference contained in the variable has been deleted.

The solution is that it was applied to avoid the error is:

• It is not enough that there is a declaration of the variable

• The variable will be initialized.
