You are working on a class that represents a database query. The class has two methods: `getType()` and `getSQL()`. You need to implement these methods according to the following specifications:

1. The `getType()` method:
   - Returns the type of the query as a string.
   - The type is stored in the private property `_type`.
   - The type can be one of the following values: "SELECT", "INSERT", "UPDATE", or "DELETE".

2. The `getSQL()` method:
   - Returns the SQL query as a string.
   - The SQL query is stored in the private property `_sql`.

Your task is to implement the `getType()` and `getSQL()` methods for the database query class.

Write the code for the `getType()` and `getSQL()` methods.

Sure, I can help you with that. Here's a basic implementation of the `getType()` and `getSQL()` methods using PHP syntax. Please note that the `_type` and `_sql` are private properties, and should be declared separately in the class.

```php
class DatabaseQuery
{
    private string $type;
    private string $sql;

    public function __construct()
    {
        // Initialize private properties
    }

    public function setType(string $type): void
    {
        $this->type = $type;
    }

    public function setSQL(string $sql): void
    {
        $this->sql = $sql;
    }

    public function getType(): string
    {
        return $this->type;
    }

    public function getSQL(): string
    {
        return $this->sql;
    }
}
```

In this class, the `__construct()` method is used to initialize the private properties `_type` and `_sql`. The `setType()` and `setSQL()` methods are used to set the respective properties, and the `getType()` and `getSQL()` methods are used to get them.

You'll need to modify this code to suit your specific use case and class structure.

Sure, here is the code for the `getType()` and `getSQL()` methods in PHP:

```php
class DatabaseQuery {
    private $_type;
    private $_sql;

    // Assuming you have a constructor or setter methods to set these properties

    public function getType() {
        if ($this->_type === "SELECT" || $this->_type === "INSERT" || $this->_type === "UPDATE" || $this->_type === "DELETE") {
            return $this->_type;
        } else {
            throw new InvalidArgumentException("Invalid query type.");
        }
    }

    public function getSQL() {
        return $this->_sql;
    }
}
```

And here is the code in Java:

```java
public class DatabaseQuery {
    private String _type;
    private String _sql;

    // Assuming you have a constructor or setter methods to set these properties

    public String getType() {
        if (_type.equals("SELECT") || _type.equals("INSERT") || _type.equals("UPDATE") || _type.equals("DELETE")) {
            return _type;
        } else {
            throw new IllegalArgumentException("Invalid query type.");
        }
    }

    public String getSQL() {
        return _sql;
    }
}
```

These methods simply return the respective private properties. The `getType()` method also includes a check to ensure that the type is one of the valid query types. If it's not, an exception is thrown.
