Solution
The output of the given Java code will be 10.
Here's the step by step explanation:
-
A 2D array arr[][] is created with 3 rows and each row has a different number of columns. The first row has 1 column, the second row has 2 columns, and the third row has 3 columns.
-
The first nested for loop assigns values to the elements of the array. For each row, it assigns values from 1 to the number of columns in that row.
-
The second nested for loop calculates the sum of all elements in the array.
-
The sum of all elements in the array is 1 (from the first row) + 1 + 2 (from the second row) + 1 + 2 + 3 (from the third row) = 10.
-
The sum is printed out, so the output of the code is 10.
