Correct Answer: B
Correct Answer: A
Given:
Correct Answer: D
Int [] [] array = {{0}, {0, 1}, {0, 2, 4}, {0, 3, 6, 9}, {0, 4, 8, 12, 16}};
Systemout.printIn(array [4] [1]);
System.out.printIn (array) [1] [4]);
Correct Answer: A
System.out.println(2 + 4 * 9 - 3); //Line 21
System.out.println((2 + 4) * 9 - 3); // Line 22
System.out.println(2 + (4 * 9) - 3); // Line 23
System.out.println(2 + 4 * (9 - 3)); // Line 24
System.out.println((2 + 4 * 9) - 3); // Line 25
