可以使用 == 来比较enum实例。 此外,java.lang.Enum实现了Comparable和 Serializable 接口,所以也提供 compareTo() 方法。 例:展示enum的基本方法 代码语言:javascript 代码运行次数:0 运行 AI代码解释 publicclassEnumMethodDemo{enumColor{RED,GREEN,BLUE;}enumSize{BIG,MIDDLE,SMALL;}publicstaticvoidmain(String ar...

ToString(String, IFormatProvider) 已过时. 此方法重载已过时;请使用ToString(String)。 ToString() 将此实例的值转换为其等效的字符串表示形式。 ToString(String) 使用指定格式将此实例的值转换成其等效的字符串表示。 ToString(IFormatProvider) 已过时. ...

public class TestMain { public static void main(String args[]) { // Color colors=new Color(100,200,300); //wrong Color color = Color.RED; System.out.println(color); // 调用了toString()方法 } } 3、所有枚举类都继承了Enum的方法,下面我们详细介绍这些方法。
