When I run First.java
The output that I get is :
java.io.NotActiveException: not in call to readObject
at java.io.ObjectInputStream.defaultReadObject(Unknown Source)
at serialization.First.readObject(First.java:153)
at serialization.First.Method(First.java:134)
at serialization.First.main(First.java:61)
Can someone explain me how to fix the issue
