Write a function named delete Letter that has 2 parameters. The first parameter is a string, the second parameter is an integer. The function removes the character located at the position specified by the integer parameter from the string. For example, if the function is being called with the following statement: deleteLetter ("timetable", 3); the string will become "tietable", where the third character, 'm' has been removed.

public  static void deleteLetter(String st,int in)

{

// remove the character at index in

 st=st.substring(0,in-1)+st.substring(in);

 System.out.println(st);

}

// main method of class

public static void main (String[] args) throws java.lang.Exception

{

   try{

//scanner object to read input

   Scanner scr=new Scanner(System.in);

// read string

   System.out.print("Enter the string:");

                    String st=scr.nextLine();

// read index

  System.out.print("Enter the index:");

  int in=scr.nextInt();

// call method

  deleteLetter(st,in);

   }catch(Exception ex){

       return;}

}

}

Explanation:

Read a string with the help of Scanner object.Then read the index of character to be remove.Call the method deleteLetter() with parameter string and index.It will make substring from 0 to "in-1" and "in" to last of the string.Then add both the string.This will be the required string.
