JAVA重写(override)toString方法 1.toString()方法 一般出现在System.out.println(类名.toString()); toString()是一种自我描述方法 本身返回的是 getClass().getName() + “@” +Integer.toHexString(hashCode()); 也就是 类名 + @ +hashCode的值 重写toString() 只会对类生效,并不能字符串生效; 2.为什...
@Override public String toString() { return String.format("(%03d) %03d-%04d", areaCode, prefix, lineNumber); } Whether or not you specify the format, provide programmatic access to all of the information contained in the value returned by toString ....

string that “textually represents” this object. The result should be a concise but informative representation that is easy for a person to read. It is recommended that all subclasses override this method. The string output is not necessarily stable over time or across JVM invocations.toString ...
1) toString() method is top most super class used perfectly by all subclasses You can use override toString() method from Object class once in topmost super class i.e. in our case AbstractUser.java. This method will be usable by all childs classes if they do not gave their own version...

return number.toString();} } 同样，在方法签名（Double而不是Number）方面只有细微的差别，但在这种情况下，它是方法的重载版本，它不覆盖父方法。如果Java编译器和@Override注解的帮助不存在，那么我们上一个例子中使用@Override注解的方法就会报编译错误。内联（Inlining）内联是由Java JIT（Just-in-time）编译器...
