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...
String s1 = new String("Compare two strings in Java"); String s2 = new String("Compare two strings in Java"); // Evaluates to true System.out.println(StringUtils.equals(s1, s2)); // Evaluates to true System.out.println(StringUtils.compare(s1, s2) == 0); } } Download Code That’...
CodePointBefore(Int32) Returns the character (Unicode code point) before the specified index. CodePointCount(Int32, Int32) Returns the number of Unicode code points in the specified text range of this String. CompareTo(String) Compares two strings lexicographically. CompareToIgnoreCase(String) ...

The equalsIgnoreCase() method compares two strings, ignoring lower case and upper case differences.This method returns true if the strings are equal, and false if not.Tip: Use the compareToIgnoreCase() method to compare two strings lexicographically, ignoring case differences....
int compareTo(String anotherString)Compares two strings lexicographically. Returns an integer indicating whether this string is greater than (result is > 0), equal to (result is = 0), or less than (result is < 0) the argument. int compareToIgnoreCase(String str)Compares two strings lexicograp...
The Java String `compareTo()` method compares two strings lexicographically (alphabetical order). It returns a positive number, negative number, or zero.
Do not compare two strings with == which looks reasonable but does not work correctly in all cases. This twoE() example method returns true if the string contains exactly two 'e' chars. The code:"for (int i=0; i<str.length(); i++) { ..." is very standard code to look at ...
There are multiple ways to compare two strings alphabetically in Java e.g.==operator,equals()method orcompareTo()method, but which one is the best way to check if two strings are equal or not? Programmers oftenconfused between == operator and equals() method, and think that comparing strin...
