//--------------------------------------------------------------------
String text = "Hello World";
char letter = text.charAt(7);
System.out.println("The character is : " +letter);

int index = text.indexOf("W");
System.out.println("Index of the letter is " +index);

String subText = text.substring(3);
System.out.println("Substring of text is : "+ subText);

String sub2 = text.substring(0, 8);
System.out.println(sub2);

String replacedText = text.replace("l", "z");
System.out.println(replacedText);
