Question

What is the output of the following code fragment:

int[] z = new int[9];
z[0] = 7;
z[1] = 3;
z[2] = 4;
System.out.println( z[0] + z[1]+" "+z[5]);
730
100
The program is defective and will not compile.
734

Answer 1

The output of the code fragment will be "10 0" since the sum of the first two initialized elements is 10, and the fifth element, which was not set, defaults to 0 in an integer array in Java.

Step-by-step explanation:

The code fragment in question is a Java snippet that initializes an array of integers and sets some values. The output of the given code will be the sum of the first two elements in the array ('z[0] + z[1]') followed by the value at the fifth position ('z[5]'), separated by a space. Since the first two elements are 7 and 3, their sum is 10. The fifth element ('z[5]') is not explicitly set in the code, so it defaults to 0 in Java as arrays are initialized with default values (0 for integers). Therefore, the output will be "10 0".
