compareTo()方法 String类实现了Comparable接口,所以我们可以直接使用compareTo()方法来比较字符串的字典序。 Stringstr1="apple";Stringstr2="banana";intresult=str1.compareTo(str2);if(result<0){System.out.println(str1+" 在字典序中排在 "+str2+" 之前");}elseif(result>0){System.out.println(str...
JavaString.compareTo()compares two strings lexicographically (in dictionary order) in a case-sensitive manner. For case-insensitive comparison, usecompareToIgnoreCase()method. 1. Strings in Lexicographic Order If a string'string1'comes before another string'string2'in the dictionary, thenstring2is s...

The result is a positive integer if this String object 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. This is the definition of lexicographic ordering. If two strings are...
How to compare String in Java? Examples The right way of comparing String in Java is to either useequals(),equalsIgnoreCase(), orcompareTo()method. You should useequals()method to check if two String contains exactly same characters in same order. It returns true if two String are equal ...

一个对象的集合根据compareTo方法以自然排序进行排序。 像Integer、String和Date这样的Java类实现了Comparable接口并覆盖了其compareTo方法,它们以词表顺序(lexicographic-order)进行排序。 从Java源代码中找到naturalOrder方法声明。 static<TextendsComparable<?superT>>Comparator<T>naturalOrder() ...
