Java StringBuffer SubString Example

  

public class Main {

  public static void main(String[] args) {
    StringBuffer sb = new StringBuffer("this is a test");

    System.out.println(sb);
    String strPart1 = sb.substring(5);

    System.out.println(strPart1);
    String strPart2 = sb.substring(0, 17);

    System.out.println(strPart2);
  }
}
