在equals()实现中使用Objects#equals方法更加简洁,并且提高了可读性: Objects.equals(birthDate, that.birthDate); 1 5.Comparable接口 比较逻辑也可用于给对象排序。可比较接口允许我们通过确定一个对象是大于、等于还是小于另一个对象来定义对象之间的顺序。 Compariable接口是泛型的,只有一个方法compareTo(),该方法...

Both primitive characters and Character objects can be compared. Let’s take a closer look at each method. Although we can use the less than and greater than operators, they only work with primitive values.To compare two char values numerically, use the compare(char x, char y) method of ...
equals();用来判断两个对象是否相等的函数,默认的是两个对象的地址比较,在使用Compare计算的时候,往往需要重写这个函数。 finalize();这个函数在对象被消解的时候,例如垃圾回收的时候等,会被调用,如果对象使用了不可被自动回收的内存空间等资源,应该在这个函数里面收回。
This interface imposes a total ordering on the objects of each class that implements it. This ordering is referred to as the class'snatural ordering, and the class'scompareTomethod is referred to as itsnatural comparison method. Lists (and arrays) of objects that implement this interface can ...
