### Explanation

- **Class Declaration**: The code defines a public class named `PS07D`.

- **Method Description**: The method `catch22()` is described using a comment block. This method is tasked with checking an integer array for two adjacent '2' values.

- **Examples**: The comments provide examples of how the method should behave:
- `catch22({1, 2, 2})` returns `true`
- `catch22({1, 2, 1, 2})` returns `false`
- `catch22({2, 1, 2})` returns `false`

- **Parameters and Return Values**:
- **@param nums**: Describes the parameter `nums` as the array to search.
- **@return**: Specifies that the method returns a boolean value (`true` or `false`) based on the presence of adjacent '2's.

- **Method Definition**: The placeholder method `catch22` is defined as returning a `boolean` value. It accepts an integer array `nums` as a parameter. Currently, it always returns `false`, indicating that the implementation is incomplete and needs to be written.

Complete the method endsInFive that takes as arguments a 2D-array of integers and an integer value that represents a column index in the array. endsInFive returns the number of values in the column that end in 5. It is possible that the array is ragged, meaning that the number of columns in each row is different. For example, 2 is returned if the following 2D-array is passed as the first argument of endsInFive and the integer 3 as the second argument (the values 25 and 115 end in five at column index 3).
