Explanation

In Java, local variables inside methods cannot have access modifiers (private, protected, public). These modifiers only apply to class members (fields and methods). Lines 2, 3, and 4 attempt to declare local variables with access modifiers, which is a compile error. Line 5 uses these variables, adding to the errors. The class-level 'int i' is valid shadowed by the local 'int i' at line 1.
