Solution

The output of the given Java code will be 4.

Here's the step by step explanation:

  1. The given 2D array is {{1, 2, 3}, {4, 5, 6}, {7, 8, 9}}.
  2. The outer loop runs from i=1 to i<3, so it will run for i=1 and i=2.
  3. The inner loop runs from j=1 to j<3, so it will run for j=1 and j=2.
  4. The sum is calculated by adding the elements at positions (i, j) in the array. So, the elements added will be array_variable[1][1] = 5, array_variable[1][2] = 6, array_variable[2][1] = 8, and array_variable[2][2] = 9.
  5. The sum of these elements is 5+6+8+9 = 28.
  6. The final output is the sum divided by 6, which is 28/6 = 4.666666666666667. But since the result is stored in an integer variable, the decimal part is truncated and the output is 4.
