在要插入equals()的地方右键-->source-->Generate hashCode()andequals()... 然后就自动生成了,删掉不要的hash就行。下面是代码- public boolean equals(Object obj) {
- if (this == obj)
- return true;
- if (obj == null)
- return false;
- if (getClass() != obj.getClass())
- return false;
- Student other = (Student) obj;
- if (age != other.age)
- return false;
- if (name == null) {
- if (other.name != null)
- return false;
- } else if (!name.equals(other.name))
- return false;
- return true;
- }
