步骤三:按字典顺序比较字符串 如果需要按照字典顺序比较两个字符串,可以使用compareTo()方法。代码如下: intresult=str1.compareTo(str2);if(result==0){System.out.println("The strings are lexicographically equal.");}elseif(result<0){System.out.println("str1 is less than str2.");}else{System.ou...
lexicographically follows the argument string. The result is zero if the strings are equal; compareTo returns 0 exactly when the equals(Object) method would return true.sort会自动调用哪个compare方法，如果他没有实现，则无法排序，也就是顺序是混乱的。另一方面，你指定了comp方法，则系统在每...
记个笔记 字符串操作类中s1.compareTo(s)规则: Compares two strings lexicographically. The comparison is based on the Unicode value of each character in the strings. The character sequence represented by thisStringobject is compared lexicographically to the character sequence represented by the argument ...

2.4. UsingcompareTo() ThecompareTo()method returns aninttype value andcompares twoStringscharacter by character lexicographicallybased on a dictionary or natural ordering. This method returns 0 if twoStringsare equal,a negative number if the firstStringcomes before the argument, and a number greater...
o1.getName().compareTo(o2.getName())的含义,对于String的compareTo方法,是按照字典顺序返回值的,如果在字典中排在后面则返回1,否则返回-1(API里解释是Compares two strings lexicographically,即按字典顺序比较两个字符串)

ThecompareTo()method compares twostringslexicographically (in the dictionary order). The comparison is based on the Unicode value of each character in the strings. Example classMain{publicstaticvoidmain(String[] args){ String str1 ="Learn Java"; ...
4. UsingString.compareTo()method Stringclass also provides thecompareTo()method, which compares two strings lexicographically, i.e., character by character based on the dictionary ordering. It returns 0 when the string is equal to the argument. Otherwise, it returns the difference between the tw...
