Thread: Efficent idea to use on this question...

  1. #1

    Default Efficent idea to use on this question...

    I'm aware I have posted several questions within the last 30 minutes and I do apologize for that. I'm just trying to learn this and grasp the concept of it. Now in this following class, I have five subjects with scores initizliaed to 40. I have one method that takes in arguments from the user. The other method that's a returning type returns the score. Rather, then having to write
    public int Pe Score()
    {return pe;}
    and
    public int sciencescore(){return science;}
    and same for the other 3 subjects. Is there another effiecnte way to write this, because writing this five times doesn't seem to be a smart method..i was just thinking of using a void and printint all of them out...

    public class StudentScore
    {
    	private int math;
    	private int science;
    	private int calc;
    	private int history;
    	private int pe;
     
    	//Make a constructor
    	public StudentScore()
    	{
    		math=40;
    		science=40;
    		calc=40;
    		history=40;
    		pe=40;
     
    	}
     
    	public void getscore(int m_score,int s_score,int c_score,int h_score,int P_score)
    	{
    		math=m_score;
    		science=s_score;
    		calc=c_score;
    		history=h_score;
    		pe=P_score;
     
     
    	}
     
    	public int Scores()
    	{
    		return math;
     
    	}
    	public int scienceScore()
    	{
    		return science;
    	}
    }

    you can actually use hashmap
    write a function which returns hashmap
    store your each subject scores in hashmap<K,V> where K is subject name and value is subject score
    and in main function u can get the subject score associated with the subject name.

    Or, each student object is an instance of a class Student that has methods to return the attributes of each Student object as they are needed. You didn't show what a 'subject' is, but I suspect they are each a loose collection of scores without form, not objects. Write a Student class, and come back if you need help.
