Java HashSet集合存储遍历学生对象代码实例

public class HashSetDemo {
  public static void main(String[] args) {
    //创建HashSet集合对象
    HashSet<Student> hashSet = new HashSet<Student>();

    //创建学生对象
    Student s1 = new Student("爱学习", 21);
    Student s2 = new Student("爱Java", 22);
    Student s3 = new Student("坚持不懈", 23);

    Student s4 = new Student("爱Java", 22);

    //把学生添加到集合
    hashSet.add(s1);
    hashSet.add(s2);
    hashSet.add(s3);
    hashSet.add(s4);

    //遍历集合(增强for循环)
    for (Student s : hashSet) {
      System.out.println(s.getName() + "," + s.getAge());
    }
  }
