Java substring: How to Extract a Substring Starting from the Third Character

This tutorial demonstrates how to use the substring() method in Java to extract a substring starting from the third character of a string.

String str = 'Hello World';
String substring = str.substring(2);
System.out.println(substring);

The code defines a string str and then uses the substring() method to obtain a substring beginning at index position 2. Since string indexing starts from 0, the third character's index is 2. The resulting substring is then printed to the console.

This results in the output:

llo World

This approach allows you to extract portions of a string based on specific character positions, enabling flexible string manipulation in your Java programs.
