Solution

The output of the given Java code would be:

i + j is 23
k is 2
j is 0

Here's the step by step explanation:

  1. The code first declares two static variables i and j and initializes them to 0.

  2. In the main method, it declares local variables i and k and assigns them the values 2 and 3 respectively.

  3. Inside the inner block, it declares another local variable j and assigns it the value 3.

  4. It then prints "i + j is " followed by the value of i and j which are 2 and 3 respectively. However, since it's a string concatenation, it doesn't add i and j but appends j to i, resulting in
