**Conditional Structures and Output in Java**

**Question:**
What is the output of the following code?

```java
int x = 5, y = 3, and z = 1;

if ( x < y )
    if ( y > z ) 
        System.out.println("x < y and y < z");
else
    System.out.println("x > y");
```

**Options:**
- ⭕ No output
- ⭕ x < y and y < z
- ⭕ x > y

**Explanation:**

In this piece of code, we start by initializing three integer variables: `x`, `y`, and `z` with the values 5, 3, and 1, respectively.

1. **First Condition:**
   The outer `if` statement checks whether `x` is less than `y`.
   ```java
   if ( x < y )
   ```

2. **Evaluation of First Condition:**
   Given `x` is 5 and `y` is 3, the condition `x < y` evaluates to `false`.

3. **Else Statement Execution:**
   Since the `x < y` condition evaluates to `false`, the `else` part of the code will be executed.
   ```java
   else
       System.out.println("x > y");
   ```

Therefore, the output of this code will be:
```
x > y
```

**Correct Answer:** ⭕ x > y
