File: A.java

class A {
   static void func() { }
}

File: B.java

class B extends A {
   static int func() { return 0; }
}

B.java:2: error: func() in B cannot override func() in A
   static int func() { return 0; }
              ^
  return type int is not compatible with void
1 error

The error message should be "func() in B cannot hide func() in A..."

Similarly when A.java is changed to be

class A {
   static final void func() { }
}

the error reported is

B.java:2: error: func() in B cannot override func() in A
   static int func() { return 0; }
              ^
  overridden method is static,final
1 error

Again, word "override" should have been "hide" and "overridden" should have been "hidden"
