Write code that prints: countNum ... 21 Print a newline after each number. Ex: If the input is: 3 the output is: 321 1 import java.util.Scanner; 3 public class ForLoops { L234567 7 8 9 10 11 12 13 14 15} public static void main (String [] args) { int countNum; int i; } Scanner input = new Scanner(System.in); input.nextInt(); countNum = for (/* Your code goes here * { System.out.println(i); }

Help me fix the code make it run out like the EXPE

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.
