问如何修复set的compareTo方法？EN在Java编程中，有时候我们需要对对象进行比较和排序。为了实现这一目标，Java提供了一个非常有用的接口叫做Comparable，以及一个重要的方法compareTo。本文将详细解释什么是Comparable接口，以及如何使用compareTo方法来比较对象。
One exception is java.math.BigDecimal, whose natural ordering equates BigDecimal objects with equal values and different precisions (such as 4.0 and 4.00). java中大部分类都保持了equals和compareTo的一致性,但有一个反例就是BigDecimal。
letkbe the smallest such index; then the string whose character at positionkhas the smaller value, as determined by using the<operator, lexicographically precedes the other string. In this case,compareToreturns the difference of the two character values at positionkin the two string -- that is,...
向TreeSet中添加元素时，首先按照compareTo的方法进行比较，一旦返回0，虽然仅是两个对象的此属性 值相同...
if(getRankValue() > other.getRankValue()) return 1; else if(getRankValue() < other.getRankValue()) return -1; else return 0; } public int getRank(){ return this.rank; } public int getSuit(){ return this.suit; } public int getRankValue() { ...
In this case, compareTo returns the difference of the two character values at position k in the two string -- that is, the value: <blockquote> text/java Kopiraj this.charAt(k)-anotherString.charAt(k) </blockquote> If there is no index position at which they differ, then the ...

One exception isjava.math.BigDecimal, whose natural ordering equatesBigDecimalobjects with equal numerical values and different representations (such as 4.0 and 4.00). ForBigDecimal.equals()to return true, the representation and numerical value of the twoBigDecimalobjects must be the same. ...
