Q1:

import java.awt.Button;
class CompareReference 
{
    public static void main(String [] args) 
    {
        float f = 42.0f;
        float [] f1 = new float[2];
        float [] f2 = new float[2];
        float [] f3 = f1;
        long x = 42;
        f1[0] = 42.0f;
    }
}
which three statements are true?
  1. f1 == f2
  2. f1 == f3
  3. f2 == f1[1]
  4. x == f1[0]
  5. f == f1[0]

A 1, 2 and 3

B 2, 4 and 5

C 3, 4 and 5

D 1, 4 and 5

ANS:A - 1, 2 and 3

(2) is correct because the reference variables f1 and f3 refer to the same array object. (4) is correct because it is legal to compare integer and floating-point types. (5) is correct because it is legal to compare a variable with an array element. (3) is incorrect because f2 is an array object and f1[1] is an array element.
