Exam 1z1-829 Topic 1 Question 18 Discussion

Actual exam question for Oracle's 1z1-829 exam
Question #: 18
Topic #: 1
Given the code fragments:

Which action prints Wagon : 200?

Suggested Answer: F Vote an answer

The code fragment is trying to read an object from a file using the ObjectInputStream class. This class throws an IOException and a ClassNotFoundException. To handle these exceptions, the main method signature should declare that it throws these exceptions. Otherwise, the code will not compile. If the main method throws these exceptions, the code will print Wagon : 200, which is the result of calling the toString method of the LuxuryCar object that was written to the file. Reference: ObjectInputStream (Java SE 17 & JDK 17) - Oracle, ObjectOutputStream (Java SE 17 & JDK 17) - Oracle
