Section 1.38 Code Refactoring

Activity 1.38.1.

There is a copy of the following code block in an interactive mode that you can modify and compile. Your task is to improve the code’s style as an expert would view it, while ensuring its behavior remains unchanged. You may run your refactored code to verify that it still passes all test cases. 
public class FileProcess {
	public static boolean canProcessFile(int fileSize, boolean hasPermission) {
		if (!hasPermission) {
			   return false; 
		}
		if (fileSize >= 1024) {
			   return false; 
		}
		return true;
	}
}

Activity 1.38.2.

Which of the following code blocks is the most similar to your final refactored code for the previous question? 
  • public class FileProcess {
	public static boolean canProcessFile(int fileSize, boolean hasPermission) {
		if (!hasPermission || fileSize >= 1024) {
			return false; 
		}
		return true;
	}
}
  • This code can further be improved!
  • public class FileProcess {
	public static boolean canProcessFile(int fileSize, boolean hasPermission) {
		if (hasPermission && fileSize < 1024) {
			return true; 
		}
		return false;
	}
}
  • This code can further be improved!
  • public class FileProcess {
	public static boolean canProcessFile(int fileSize, boolean hasPermission) {
		return hasPermission && fileSize < 1024;
	}
}
  • You refactored correctly!
