Case sensitive string comparison in Java.

You can compare two strings using either equals() method or compareTo() method.


  • The equals() method compares this string to the specified object.
  • The compareTo() method compares two strings lexicographically. The comparison is based on the Unicode value of each character in the strings.

These two methods compare the given strings with respective to Case i.e. String with the different case are treated differently.


Following example demonstrates the comparison of two strings using the equals() method.
