Java String compareTo方法Java String compareTo()方法用于按字典顺序比较两个字符串。两个字符串的每个字符都转换为 Unicode 值以进行比较。如果两个字符串都相等,则此方法返回 0,否则返回正值或负值。如果第一个字符串按字典顺序大于第二个字符串,则结果为正,否则结果为负。Java Str

Java String compareTo() Method: The compareTo() method compares two strings lexicographically. The comparison is based on the Unicode value of each character in the strings.
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...
