We're learning about creating classes, so i have my class titled Student.java and my 'driver' called grades.java. I'm trying to create a method in Student.java that will compare 2 students in Grades. I'm pretty new to programming so forgive my crappy comments and terminology. here's my codes: /* Student.java Defines a student class that stores name, score on test 1, and score on test 2. Methods prompt for and read in grades, compute the average, and return a string containing student’s info. */ public class Student { private String name; private int testOne; private int testTwo; /* Constructs a student with a given name and default test scores. */ public Student(String studentName) { name = studentName; testOne = 0; testTwo = 0; } /* Returns the student's name */ public String getName() { return name; } /* Changes the student's name */ public void setName(String newName) { name = newName; } /* Returns the student's first score */ public int getTestOne() { return testOne; } /* Changes the student's first score */ public void setTestOne(int newScore) { testOne = newScore; } /* Returns the student's second score */ public int getTestTwo() { return testTwo; } /* Changes the student's second score */ public void setTestTwo(int newScore) { testTwo = newScore; } /* Computes and returns the student's test average */ public int getAverage() { return ((testOne + testTwo)/2); } /* Returns a string of the student's name, test score #1, testscore #2, e.g., Name:Joe Test1:84 Test2:100 */ public String toString() { return ("Name:" + name + " Test1:" + testOne + " Test2:" + testTwo); } /* Returns true if this student is the same as the other one false otherwise. It is a comparison of all instance variables. */ /* public boolean equals(Object obj); { if ( obj == null || ! ( obj instanceof Student ) ) { return false; } if ( name != name ) { // and so on return false; } // ASSERT o.hashCode ( ) == hashCode ( ) return true; } */ } Code (markup): // **************************************************************** // Grades.java // // Use Student class to get test grades for two students // and compute averages // // **************************************************************** import java.util.Scanner; public class Grades { public static void main(String[] args) { String name, name1, name2; Object test; int testOne, testTwo, average; Scanner scan = new Scanner (System.in); //student 1 with hardcoded scores and name Student student1 = new Student( "Billy" ); name1 = student1.getName(); student1.setTestOne(30); student1.setTestTwo(25); System.out.println(student1.toString()); System.out.println(student1.getAverage()); /* //commented out to test equal method //student 2 with hardcoded scores and name Student student2 = new Student("Mandy"); name2 = student2.getName(); student2.setTestOne(100); student2.setTestTwo(101); System.out.println(student2.toString()); System.out.println(student2.getAverage()); */ //student 2(duplicate) with hardcoded scores and name Student student2 = new Student("Billy"); name2 = student2.getName(); student2.setTestOne(30); student2.setTestTwo(25); System.out.println(student2.toString()); System.out.println(student2.getAverage()); //compare to see if students are the same; will print either true(if same) or false System.out.println(student1.equals(student2)); } } Code (markup):
Nope, obviously the marketing department thought it was a good idea. Loads of people make the same mistake. Good luck on your finals! delete the first post. (Click 'Edit Post' for the delete option)
