Question
What is the output of the following code?int x = 30;int[] numbers = new int[x];x = 60;System.out.println("x is " + x);System.out.println("The size of numbers is " + numbers.length)
Solution
The output of the code will be:
x is 60 The size of numbers is 30
Explanation: In the first line, an integer x is declared and initialized to 30. In the second line, an array of integers named numbers is declared and its size is set to the current value of x, which is 30. In the third line, the value of x is changed to 60. However, changing the value of x does not affect the size of the array numbers because the size was set when the array was created and cannot be changed afterwards. So, when we print the value of x, it is 60, and when we print the length of the array numbers, it is still 30.
