Chapter 7, Problem 1PE

Explanation of Solution

Program:

File name: “InputCharacterInfo.java”

//Import necessary header files

import java.util.Scanner;

//Define a class named InputCharacterInfo

public class InputCharacterInfo

{

    //Define main method

    public static void main(String[] args)

    {

        //Create an object to the Scanner class

        Scanner sc = new Scanner(System.in);

        //Prompt the user to enter a character

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

        char aChar = sc.nextLine().charAt(0);

        //Tests if character is uppercase

        if (Character.isUpperCase(aChar))

        {

            //Print the result

            System.out.println(aChar + " is uppercase");

        }

        //Else condition

        else

        {

            //Print the result

            System.out.println(aChar + " is not uppercase");

        }

        //Tests if character is lowercase

        if (Character.isLowerCase(aChar))

        {

            //Print the result

            System.out.println(aChar + " is lowercase");

        }

        //Else condition

        else

        {

            //Print the result

            System.out.println(aChar + " is not lowercase");

        }

        //Returns the uppercase equivalent of the character

        aChar = Character...
