Answer:
The name of a .java file should <u>always match the name of the class inside.</u>
Explanation:
In Java programming the program written in code editor is first saved with .java extension. The name of this .java file should be same as that of the class declared inside the file.
This .java file is then compiled and converted to .class file which contains the java bytecode. This bytecode can then be executed by java virtual machine(JVM).
However it is not always necessary that name of .java files should be same as that of class inside it. The name should be same only when the class inside is declared as public.
In case it is not declared as public one can name .java file different than the actual class name.
Answer:
This is not a good solution

Answer: hello your question lacks the required option, below are the missing options
A. The transaction data in the tampered block is deleted, and a copy is created with the same hash value.
B. The hash values of transaction data of subsequent blocks are validated, and the chain is broken.
C. The hash value for the entire block is nullified, creating a domino effect on all subsequent blocks.
D. The hash values of subsequent blocks are updated as soon as they are tampered with, and the chain continues.
answer : The hash values of subsequent blocks are updated as soon as they are tampered with, and the chain continues ( D )
Explanation:
What happens if a transaction data is changed in an earlier existing block in a Blockchain is that the Hash values of subsequent blocks will be updated as soon as they are tampered with and the chain will continue.
Blockchain is a specially design system for recording information, hence any change in data inputted in an earlier existing blocks that changes will automatically be updated as well in all preceding blocks.
