II) Member level access modifiers (java variables and java methods)
All the four public, private, protected and no modifier is allowed.
For better understanding, member level access is formulated as a table:
Access Modifiers |
Same Class | Same Package | Subclass | Other packages |
public | Y | Y | Y | Y |
protected | Y | Y | Y | N |
no access modifier | Y | Y | N | N |
private | Y | N | N | N |
First row {public Y Y Y Y} should be interpreted as:
Second row {protected Y Y Y N} should be interpreted as:
similarly interpret the access modifiers table for the third (no access modifier) and fourth (private access modifier) records.
