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: AI检测代码解析 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.out.println("st...
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 ...
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 than zero if the firs...
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...
Comparing strings using compareTo() and compareToIgnoreCase() method firstString.compareTo(secondString) : 7 firstString.compareTo(thirdString) : -9 secondString.compareToIgnoreCase(fourthString) : 0 I have written a detailed article onhow to compare strings lexicographically in java.

6、compareTo 方法 compareTo(String anotherString)Compares two strings lexicographically. 按照字典顺序比较两个字符串,相等返回 0,在 anotherString 前面返回小于 0 的值,否则返回大于 0 的值。 String str = "hello, google"; System.out.println("compare with baidu: " + str.compareTo("hello, baidu")...
String class also provides the compareTo() 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 two character values present at...
The compareTo() method is used to compare two strings lexicographically. This method returns an integer value:0 if the strings are equal, A negative integer if the first string is lexicographically less than the second string, A positive integer if the first string is lexicographically greater ...
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"; ...
