Compariable接口是泛型的,只有一个方法compareTo(),该方法接受泛型类型的参数并返回int。如果当前值小于参数,则返回负值;如果它们相等,则返回0;否则返回正值。 比方说,在我们的Person类中,我们希望按Person对象的姓氏进行比较: public class Person implements Comparable<Person> { //... @Override public int comp...
Objects.equals(birthDate, that.birthDate); 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(),该方法接受泛型类型的参数并返回int。如果当前值小于参数,则返回负值;如果它们相...

This class consists of static utility methods for operating on objects, or checking certain conditions before operation. These utilities include null-safe or null-tolerant methods for computing the hash code of an object, returning a string for an object, comparing two objects, and checking if ...
CompareTo(Integer) Compares two Integer objects numerically. CompareUnsigned(Int32, Int32) Compares two int values numerically treating the values as unsigned. Decode(String) Decodes a String into an Integer. Dispose() (Inherited from Object) Dispose(Boolean) (Inherited from Object) DivideUnsigne...
