??Set<Teacher>?s1=new?HashSet<Teacher>(); ?????s1.add(t1);//這邊是S1 ?????s1.add(t2);//這邊是S1 ?????s1.add(t3);//這邊是S1 ????? ?????Set<Teacher>?s2=new?HashSet<Teacher>(); ?????s1.add(t1);//這邊是S1,這邊不應該是s2.add(t1)?依次類推 ?????s1.add(t4);//這邊是S1 ?????s1.add(t3);//這邊是S1 ????? ?????Set<Teacher>?s3=new?HashSet<Teacher>(); ?????s1.add(t1);//這邊是S1 ?????s1.add(t2);//這邊是S1 ?????s1.add(t4);//這邊是S1 ????? ?????Set<Teacher>?s4=new?HashSet<Teacher>(); ?????s1.add(t3);//這邊是S1 ?????s1.add(t2);//這邊是S1 ?????s1.add(t4);//這邊是S1
