Thread: Problems with Assignment in Java II

Write a class encapsualting the concept of a course grade, assuming a course grade
* has the following attributes: a course name and a letter grade. Include a constructor,
* the accessor and mutator, and methods toString and equals.Write a client class
* to test all the methods in your class.

Here is my code so far not sure how to test and finish the toString and equals method in this code ? Any help would be much appreciated.

package labmodule7num57;
import java.util.*;

public class LabModule7Num57 {
// Constructors//
private String name;
private String letterGrade;
public LabModule7Num57 (String name,String letterGrade) {

this.name = name;
this.name =letterGrade;
}
// Setting the name of course and letter grade//
public void setName(String name,String letterGrade) {

this.name = name;
this.name =letterGrade;
}
// Getting the name of the course//
public String getName() {

return name;
}
// Getting the name of the letter grade//
public String getletterGrade() {

return letterGrade;
}
// Returning the name of the course and the letter grade//
public String toString() {

return name+":"+letterGrade;

}


public static void main(String[] args) {
// TODO code application logic here
}
}

equals may be something like this:

public boolean equals(Object obj){
        if (!(obj instanceof LabModule7Num57))
            return false;
        LabModule7Num57 entry = (LabModule7Num57)obj;
        return this.name.equals(entry.name) &&               
               this.letterGrade.equals(entry.letterGrade);
    }

I'd add hashCode() function:

public int hashCode(){
        int hash = 37;
        hash = hash*17 + this.name.hashCode();
        hash = hash*17 + this.letterGrade.hashCode();
        return hash;
    }
