Which three form part of correct array declarations? 1. public int a [ ] 2. static int [ ] a 3. public [ ] int a 4. private int a [3] 5. private int [3] a [ ] 6. public final int [ ] a

(1), (2) and (6) are valid array declarations. Option (3) is not a correct array declaration. The compiler complains with: illegal start of type. The brackets are in the wrong place. The following would work: public int[ ] a Option (4) is not a correct array declaration. The compiler complains with: ']' expected. A closing bracket is expected in place of the 3. The following works: private int a [] Option (5) is not a correct array declaration. The compiler complains with 2 errors: ']' expected. A closing bracket is expected in place of the 3 and <identifier> expected A variable name is expected after a[ ] .
