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.

Using Java.

2-7 Given the code below, which lines are valid and invalid.

import java.util.Scanner; public class LabProgram {   /* Define your method here */      public static void main(String[] args) {      Scanner scnr = new Scanner(System.in);       /* Type your code here. */   }}

import java.util.Scanner;public class main{public static void main(String[] args){Scanner sc = new Scanner(System.in):int year, day, weekday;String month;String outday = "";System.out.printf("Enter the month%n");month = sc.nextLine();System.out.printf("Enter the day%n");month = sc.nextInt();weekay = find_day(month, day);outday = out_weekday(weekday);System.out.printf("The day is: %s%n", outday);}} Change the program from the previous example to take command line arguments instead of using the Scanner. For example, running the program like this:>           java OutDays March 14will output the weekday string (which is Thursday) on the console for March 14, 2019). public static void main(String[] args){    int year, day, weekday;    String month;    String outday = "";    // #### your code here for accessing the command line arguments    weekday = find_day(month, day);    outday = out_weekday(weekday);    System.out.printf("The day is: %s%n", outday);}

I have this code: import java.util.Scanner; public class CalcTax {     public static void main(String[] args) {        Scanner sc = new Scanner(System.in);         // Welcome message        System.out.println("Welcome to my tax calculation program.");         // Declare the variables        int i, pinCode, maxRetries = 3;        String choice;         // Get the PIN code        for (i = 0; i < maxRetries; i++) {            System.out.print("Please enter the PIN code: ");            pinCode = sc.nextInt();            if (pinCode == 5678) {                break;            }            System.out.println("Invalid pin code. Please try again.");        }        if (i == maxRetries) {            System.out.println("Invalid pin code. You have reached the maximum number of retries.");            System.exit(0);        }         // Get the income, interest, deduction, and paid tax amount        double income, interest, deduction, paidTax;        do {            System.out.print("Please…
