Write a method named showChar. The method should accept two arguments: a reference to a String object and an integer. The intege

matrenka [14]

A complete program with the method ShowCar:

import java.util.Scanner; // header file

public class ShowChar

{

public static void main(String[] args)

{

String lnOfText;

int i;

Scanner input = new Scanner(System.in);

System.out.print("Enter a line of text:");

lnOfText = input.nextLine();

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

i = input.nextInt();

show_Char(lnOfText,i);

}

public static void show_Char(String str_a, int i)

{

System.out.print(str_a.charAt(i));

}

In this program, both the inputs ie. a sentence or line of text as well as the index position is obtained. A method is written to find the string at that particular position. Finally the method prints that character at the particular index.

LAB: Praising dates

blsea [12.9K]

Answer:

Explanation:

The following is the entire modified code, it takes in the date as an input and continues changing the dates to the desired format. If the input format is wrong it says "Wrong Format" and requests another input. If -1 is passed as an input the program terminates.

import java.util.Scanner;

class DateParser {

public static int getMonthAsInt(String monthString) {

int monthInt;

switch (monthString) {

case "January" :

monthInt = 1;

break;

case "February":

monthInt = 2;

break;

case "March":

monthInt = 3;

break;

case "April":

monthInt = 4;

break;

case "May":

monthInt = 5;

break;

case "June":

monthInt = 6;

break;

case "July":

monthInt = 7;

break;

case "August":

monthInt = 8;

break;

case "September":

monthInt = 9;

break;

case "October":

monthInt = 10;

break;

case "November":

monthInt = 11;

break;

case "December":

monthInt = 12;

break;

default:

monthInt = 0;

}

return monthInt;

}

public static void main(String[] args) {

Scanner scnr = new Scanner(System.in);

// TODO: Read dates from input, parse the dates to find the one

// in the correct format, and output in m/d/yyyy format

String date = "";

while (!date.equals("-1")) {

String month = "";

String day = "";

String year = "";

System.out.println("Enter date:");

date = scnr.nextLine();

try {

year = date.substring((date.length()-4), date.length());

if (Character.isDigit(date.charAt(date.length()-8))) {

day = date.substring((date.length()-8), date.length()-6);

month = date.substring(0, date.length()-9);

} else {

day = date.substring((date.length()-7), date.length()-6);

month = date.substring(0, date.length()-8);

}

if ((year.length() == 4) && (day.length() > 0) && (day.length() <= 2) && (month.length() >= 3)) {

System.out.println(getMonthAsInt(month) + "/" + day + "/" + year);

} else {

System.out.println("Wrong Format");

}

} catch (Exception e) {

System.out.println("Wrong Format");

}
