Описание: In this video, we dive into the world of Java String methods. Strings are an essential part of Java, and mastering them can significantly enhance your coding skills. Whether you’re a beginner or looking to brush up on your knowledge, this tutorial covers basic methods you need to know about working with Strings in Java.

Lets learn the functions - length(), toUpperCase(), toLowerCase(), charAt(), indexOf(), substring(), replace()

Please find the code below:

*/

public static void main(String[] args) {

String name = "Akshay Kumar";

//--------------------------------------------------------------------
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);
