Question

public linter(list checks) constructs a linter given a list of checks to run through. public list lint(string filename) throws filenotfoundexception lints the given files line-by-line by running through all the checks passed into the constructor. you should first open the file (specified by filename) and read through the file line-by-line. you can use the file and scanner classes to help open and read the file line-by-line. for each line, run through all the checks and add errors if they are present. returns a list of all errors found.

Answer 1

The question is about constructing a linter in Java that involves reading a file line-by-line, applying specified checks to each line, and returning a list of errors. It falls under the College-level Computers and Technology subject.

Step-by-step explanation:

Constructing a Linter in Java

The mentioned code represents a task related to Computers and Technology, specifically a problem in the realm of software engineering or computer science focused on the development of a linter. A linter is a tool that analyzes source code to flag programming errors, bugs, stylistic errors, and suspicious constructs.

The public linter(list checks) constructor is expected to take a list of checks, which are probably methods or rules to apply to the source code. The method public list lint(string filename) takes a filename as an input and throws a FileNotFoundException if the file does not exist. The task involves writing Java code that uses the File and Scanner classes to read the file line-by-line and apply all the checks to each line to find errors. Therefore, the answer would be explaining the Java implementation for this problem, introducing the use of these classes for file operations and applying the checks to each line while collecting the errors to return.
