Question
### What is the output when the following code is executed? ```java x = 1; y = 1; switch (x + 1) { case 2: y = 2; default: y += 1; } System.out.println(y); ``` - ○ 2 - ○ 3 - ○ 1 ### Explanation This code snippet demonstrates a `switch` statement in Java. 1. **Variables Initialization:** - `x` is set to 1. - `y` is set to 1. 2. **Switch Statement:** - The statement evaluates `x + 1`, which is `2`. - It matches `case 2:`, setting `y = 2`. - Since there is no `break;` statement after the `case 2`, the program continues to the `default` block. - In the `default` block, `y` is incremented by 1 (`y += 1`), making `y = 3`. 3. **Output:** - The value of `y` is printed, resulting in `3`. Thus, the correct answer is: - ○ 3
