Answer:
1)
- The data variables in the class are called as fields
Therefore the correct answer is “field”.
2)
- The functions in the class are called as methods.
Therefore the correct answer is “method”.
3)
- To prevent from changing an attribute value outside the code, the variable should be declared as private. This can be done by prefixing the two underscore characters before the variable name.
Therefore the correct answer is “the variable is private and cannot be seen by outside code”.
