Typo (Part 6 -> Separating the user interface from program logic -> example of simple manual testing (just before User interface Section)

Given:

GradeRegister register = new GradeRegister();
register.addGradeBasedOnPoints(51);
register.addGradeBasedOnPoints(50);
register.addGradeBasedOnPoints(49);

System.out.println("Number of students with grade 0 (should be 1): " + register.numberOfGrades(0);
System.out.println("Number of students with grade 0 (should be 2): " + register.numberOfGrades(2);

Expected:

GradeRegister register = new GradeRegister();
register.addGradeBasedOnPoints(51);
register.addGradeBasedOnPoints(50);
register.addGradeBasedOnPoints(49);

System.out.println("Number of students with grade 0 (should be 1): " + register.numberOfGrades(0);
System.out.println("Number of students with grade 2 (should be 2): " + register.numberOfGrades(2);
