Question

In a Package called characterArray, ********JAVA CODE**********
1) Create a char array containing your full name and print it out.
2) Create an uninitialized char array and copy into it
     the char array containing your full name and print it out.
3) Create a Character array and copy into it the char array containing
     your full name and print it out.
4) Into the Character array, use toUpperCase() to copy the char array containing
    your full name and print it out.
5) Convert the Characters in place using toLowerCase() and charValue()
     to lowercase Characters.

Answer 1

thanks for the question, here is the code in Java, when you run the program please update the char array with yoru full name.

Comments given for you to identify the code for each sub parts

========================================================================

public class CharArray {

    public static void main(String[] args) {

        // 1. Create a char array containing your full name
        System.out.println("Part 1");
        char name[] = {'B', 'a', 'r', 'a', 'c', 'k', ' ', 'O', 'b', 'a', 'm', 'a'};
        // print it out
        for (int i = 0; i < name.length; i++) {
            System.out.printf("%c", name[i]);
        }
        System.out.println("\n\nPart 2");

        // 2 Create an unitialized char array and copy into it
        char duplicate[] = new char[name.length];
        for (int i = 0; i < name.length; i++) duplicate[i] = name[i];
        // print it out
        for (int i = 0; i < name.length; i++) {
            System.out.printf("%c", duplicate[i]);
        }
        System.out.println("\n\nPart 3");

        //3. Create a Character array
        Character duplicateObject[] = new Character[name.length];
        for (int i = 0; i < name.length; i++) duplicateObject[i] = new Character(name[i]);
        // print it out
        for (int i = 0; i < name.length; i++) {
            System.out.printf("%c", duplicateObject[i]);
      }
        System.out.println("\n\nPart 4");


        //5. use to UpperCase to copy the char array
        for (int i = 0; i < name.length; i++) duplicateObject[i] = Character.toUpperCase(duplicateObject[i]);
        for (int i = 0; i < name.length; i++) {
            System.out.printf("%c", duplicateObject[i]);
        }
        System.out.println("\n\nPart 5");

        // 6. Convert the characters to lower case using tolowercae and charvalue
        for (int i = 0; i < name.length; i++)
           duplicateObject[i] = Character.toLowerCase(duplicateObject[i]);
        for (int i = 0; i < name.length; i++) {
            System.out.printf("%c", duplicateObject[i].charValue());
        }

    }
}
