### What will this small program output?```javaclass Main { private static void foo() { x = 7; } private static int x = 13; public static void main(String[] args) { int x = 24; foo(); System.out.println(x); }}```#### Explanation:1. The class `Main` includes a static method `foo()`, a static integer variable `x`, and the `main` method.2. The `foo()` method sets the static variable `x` to 7.3. The static variable `x` is initially set to 13.4. Inside the `main` method, a local `x` variable is declared and initialized to 24, which shadows the static variable `x`.5. The `foo()` method is called, which changes the value of the static variable `x` to 7, but does not affect the local variable `x` declared inside `main`.6. Finally, the `main` method prints the local variable `x`, which is still 24.#### Expected Output:```plaintext24```

Question

### What will this small program output?

```java
class Main {
private static void foo() {
x = 7;
}

private static int x = 13;

public static void main(String[] args) {
int x = 24;
foo();
System.out.println(x);
}
}
```

#### Explanation:
1. The class `Main` includes a static method `foo()`, a static integer variable `x`, and the `main` method.
2. The `foo()` method sets the static variable `x` to 7.
3. The static variable `x` is initially set to 13.
4. Inside the `main` method, a local `x` variable is declared and initialized to 24, which shadows the static variable `x`.
5. The `foo()` method is called, which changes the value of the static variable `x` to 7, but does not affect the local variable `x` declared inside `main`.
6. Finally, the `main` method prints the local variable `x`, which is still 24.

#### Expected Output:
```plaintext
24
```
