比较Java中不同类的对象字段

如果有两个类的字段具有相似的含义，则可以考虑声明一个

interface

Class1 implements MyInterface {    int firstProperty;    String secondProperty;    ...    int getOne() {        return firstProperty;    }    String getTwo() {        return secondProperty;    }}Class2 implements MyInterface {    int propertyOne;    String propertyTwo;    ...    int getOne() {        return propertyOne;    }    String getTwo() {        return propertyTwo;    ...}

并且

interface

isEqualTo

MyInterface {    int getOne();    String getTwo();    ...    boolean isEqualTo(MyInterface that) {        return that != null && this.getOne() == that.getOne() && this.getTwo().equals(that.getTwo()) && //add null checks! ...;    }}

有

isEqualTo
