Given: 1. class Comp2 { 2. public static void main(String[] args) { 3. float f1 = 2.3f; 4. float[][] f2 = {{42.Of}, {l.7f, 2.3f}, {2.6f, 2.7f}}; 5. float[] f3 = {2.7f}; 6. Long x = 42L; 7. // insert code here 8. System.out.println("true"); 9. } 10. } And the following five code fragments: F1. if (f1 == f2) F2. if (f1 == f2[2][1]) F3. if (x == f2[0][0]) F4. if (f1 == f2 [1,1]) F5. if (f3 == f2 [2]) What is true?
