Practice Code Structure

Section 1.19 Code Refactoring

Activity 1.19.1.

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 Scholarship {
	public static String getScholarshipEligibility(int schoolYear, double GPA, boolean hasResearchExperience) {
		if (schoolYear >= 4) {
			if (GPA >= 3.5) {
				if (hasResearchExperience == true) {
					return "Eligible";
				} 
			} 
		} 
		return "Not eligible";
	}
}

Activity 1.19.2.

    Which of the following code blocks is the most similar to your final refactored code for the previous question?
  • public class Scholarship {   
      public static String getScholarshipEligibility(int schoolYear, double GPA, boolean hasResearchExperience) {
        if (schoolYear >= 4 && GPA >= 3.5 && hasResearchExperience == true) {
          return "Eligible";
        } 
        return "Not eligible";
      }
    }
    
  • This code can improve further!
  • public class Scholarship {   
      public static String getScholarshipEligibility(int schoolYear, double GPA, boolean hasResearchExperience) {
        if (schoolYear >= 4 || GPA >= 3.5 || hasResearchExperience == true) {
          return "Eligible";
        } 
        return "Not eligible";
      }
    }
    
  • The code doesn’t have the same functionality with the original one. Copy the original code into the interactive section and try refactoring it again.
  • public class Scholarship {   
      public static String getScholarshipEligibility(int schoolYear, double GPA, boolean hasResearchExperience) {
        if (schoolYear >= 4 && GPA >= 3.5 && hasResearchExperience) {
          return "Eligible";
        } 
        return "Not eligible";
      }
    }
    
  • You refactored correctly!
