Example
String myStr1 = "Hello";
String myStr2 = "Hello";
System.out.println(myStr1.compareTo(myStr2)); // Returns 0 because they are equalDefinition and Usage
The compareTo() method compares two strings lexicographically.
The comparison is based on the Unicode value of each character in the strings.
The method returns 0 if the string is equal to the other string. A value less than 0 is returned if the string is less than the other string (less characters) and a value greater than 0 if the string is greater than the other string (more characters).
Tip
Use compareToIgnoreCase() to compare two strings lexicographyically, ignoring lower case and upper case differences.
Tip
Use the equals() method to compare two strings without consideration of Unicode values.
