Question
What is the output of this program? class Output { public static void main(String args[]) { int a1[] = new int[10]; int a2[] = {1, 2, 3, 4, 5}; System.out.println(a1.length + " " + a2.length); } }Select one:a.0 5b.10 5c.5 10d.0 10
Solution
The output of the program will be "10 5". So, the correct answer is b. 10 5.
Here's the step by step explanation:
- The program defines two arrays: a1 and a2.
- a1 is defined with a length of 10 but no values are assigned to it.
- a2 is defined with a length of 5 and values 1, 2, 3, 4, 5 are assigned to it.
- The program then prints the length of a1 and a2, which are 10 and 5 respectively.
