Example
String myStr1 = "HELLO";
String myStr2 = "hello";
System.out.println(myStr1.compareToIgnoreCase(myStr2));Definition and Usage
The compareToIgnoreCase() method compares two strings lexicographically, ignoring lower case and upper case differences.
The comparison is based on the Unicode value of each character in the string converted to lower case.
The method returns 0 if the string is equal to the other string, ignoring case differences. 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).
