Case sensitive string comparison in Java

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

Where,

• 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.

Example

The following example demonstrates the comparison of two strings using the equals() method ?

public class Sample{ public static void main(String args[]) { String str = "Hello World"; String anotherString = "hello world"; Object objStr = str; System.out.println( str.equals(anotherString) ); } }

Output

false
