Write a recursive method that displays a string reversely on the console using the following header: String reverse(String value) Sample run: Input: abcd Output: dcba

in java Write code that prints: firstNumber … 2 1Print a newline after each number. Ex: If the input is: 3 the output is: 3 2 1 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15       import java.util.Scanner;   public class ForLoops { publicstaticvoidmain (String [] args) { intfirstNumber; inti;   Scannerinput=newScanner(System.in); firstNumber=input.nextInt();   for () { System.out.println(i); } } }

Given string inputStr on one line and integers idx1 and idx2 on a second line, output "Match found" if the character at index idx1 of inputStr is equal to the character at index idx2. Otherwise, output "Match not found". End with a newline. Ex: If the input is: eerie 4 1 then the output is: Match found Note: Assume the length of string inputStr is greater than or equal to both idx1 and idx2.
