Java實(shí)現(xiàn)校園注冊(cè)登錄系統(tǒng)代碼

本文分享的是Java實(shí)現(xiàn)校園注冊(cè)登錄系統(tǒng)的代碼，為大家分析用Java實(shí)現(xiàn)校園注冊(cè)登錄系統(tǒng)的具體實(shí)現(xiàn)。閱讀完整文相信大家都能學(xué)會(huì)用java設(shè)計(jì)自己的系統(tǒng)。

代碼展示：
package com.entity;

public class Teacher {
private int id;
private String name;
private String sex;
private int age;
public Teacher(){
super();
}
public Teacher(int id, String name) {
super();
this.id = id;
this.name = name;
}
public Teacher(int id, String name, String sex, int age) {
super();
this.id = id;
this.name = name;
this.sex = sex;
this.age = age;
}
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getSex() {
return sex;
}
public void setSex(String sex) {
this.sex = sex;
}
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
public String toString() {
return "教師 工號(hào)：" + id + " 姓名：" + name + " 性別：" + sex

• " 年齡：" + age;
  }
  public int hashCode() {
  return id;
  }
  public boolean equals(Object obj) {
  if (this == obj)
  return true;
  if (obj == null)
  return false;
  if(obj instanceof Teacher){
  Teacher other=(Teacher)obj;
  return id==other.id&&name.equals(other.name);
  }
  return false;
  }

}
