Can someone help me, please?
I want to finish the homework before December 17, but now, I have a
problem with LAB 1043 homework (Serialization).
I cannot display the fields of Profile Class and School Class in a
serialized file.
When run the serialized part, I have the next Exception:
*************************************************************************************
Exception in thread "main" java.lang.NullPointerException
at
SerializeMyClassToBePersisted.main(SerializeMyClassToBePersisted.java:32)
Java Result: 1
*************************************************************************************
I did the next:
1.- Write MyClassToBePersisted.java con serialized clause and default
constructor.
- Profile profile;
- School school;
- Class Profile with fields and getters and setters
- Class School wit fields and getters and setters.
2.- Write SerializeMyClassToBePersisted.java this data:
MyClassToBePersisted myFields = new MyClassToBePersisted();
myFields.profile.name = "name1";
myFields.profile.age = 10;
myFields.profile.hobby = "hobby1";
myFields.school.nameOfSchool = "name College";
myFields.school.yearStarted = 2000;
The line where is the Exception is the first of the previous block:
myFields.profile.name = "name1"; ---à here is the Exception
3.- Write the DeserializeMyClassToBePersisted.java
Would you give advice to solve the problem.
Thanks in advance.
