Given the code fragment:
public static void main(String[] args) { int iArray[] = {65, 68, 69}; iArray[2] = iArray[0]; iArray[0] = iArray[1]; iArray[1] = iArray[2]; for (int element : iArray) { System.out.print(element + " "); }

• A.68, 65, 69
• B.65, 68, 69
• C.68, 65, 65
• D.65, 68, 65
• E.Compilation fails

Given the code fragment:

What values of x, y, z will produce the following result?

1 2 3 4
1 2 3 4
1 2 3 4

• A.X = 2, Y = 3, Z = 4
• B.X = 2, Y = 3, Z = 3
• C.X = 3, Y = 2, Z = 3
• D.X = 4, Y = 2, Z = 3
• E.X = 4, Y = 3, Z = 2

int i, j=0; i = (3* 2 +4 +5 ) ; j = (3 * ((2+4) + 5)); System.out.println("i:"+ i + "\nj":+j);
What is the result?

• A.Option C
