Escape Sequence In java

Question: Create a letter format using eScape sequence.

Example--

Dear khare ,

Thanks Java couse is nice. Thanks

Ans: 

package learning;

import java.util.Scanner;

public class learnNew {

public static void main(String[] args) {

// Scanner scan = new Scanner(System.in);

// String myString = "This space contains double and triple spaces";

// System.out.println(myString.indexOf(" "));

// System.out.println(myString.indexOf(" "));

//

//

//

//

// problem 5

String letter2 = "Dear khare ,\n\tThanks to buy our product. Thanks" ;

System.out.println(letter2);

}

}

Here I'm using back slash \ n and back slash \t 

What is this ?🤔🤔

Let me clear this 

            \n = this is a escape sequence character to create a new line .

            \t  = this is a escape sequence character and its represent to TAB
