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 string. T...
21. 在上面的示例中,我们定义了一个名为compareFirstThreeChars()的静态方法,用于对比两个字符串的前三个字符是否相等。首先,我们通过substring()方法从两个字符串中提取出前三个字符,然后使用startsWith()方法来比较这两个子字符串。 在main()方法中,我们调用compareFirstThreeChars()方法,并传入了两个示例字符串。

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 different, then either they have different characters at some index that is a valid index for both...
