JAVA QUESTION.

57. Write a class encapsulating 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. BELOW IS THE CLIENT AND I NEED A TEST CLASS!

public class CourseGradeClient { public static void main( String [] args ) { CourseGrade cg1 = new CourseGrade( "CS1", 'A' ); CourseGrade cg2 = new CourseGrade( "CS2", 'B' ); System.out.println( "The course of course grade #1 is " + cg1.getCourseName( ) ); System.out.println( "The grade of course grade #1 is " + cg1.getGrade( ) ); System.out.println( "Course Grade #2 is " + cg2.toString( ) );

if ( cg1.equals( cg2 ) ) System.out.println( "Original CourseGrade #1 and #2 are identical" ); else System.out.println( "Original CourseGrade #1 and #2 are different" );

cg2.setCourseName( "CS1" ); cg2.setGrade( 'A' );

if ( cg1.equals( cg2 ) ) System.out.println( "Original CourseGrade #1 and modified CourseGrade #2 are identical" ); else System.out.println( "Original CourseGrade #1 and modified CourseGrade #2 are different" );

} }
