Android 开发问题：Suspicious equality check: equals() is not implemented in

Suspicious equality check: equals() is not implemented in com. my. paging. model. entity. Student

• 为 Student 类实现 equals 和 hashCode 方法，以便正确比较两个 Student 对象是否相等

// 原来是这样的publicclassStudent{privateintid;privateStringname;privateintage;// 构造方法、getter 和 setter 省略...}

// 修改成这样publicclassStudent{privateintid;privateStringname;privateintage;// 构造方法、getter 和 setter 省略...@Overridepublicbooleanequals(Objecto){if(this==o)returntrue;if(o==null||getClass()!=o.getClass())returnfalse;Studentstudent=(Student)o;returnid==student.id&&age==student.age&&Objects.equals(name,student.name);}@OverridepublicinthashCode(){returnObjects.hash(id,name,age);}}
