Strings manipulation

 Objetive

Write a java program that asks the user for a string and:

- Replace all lowercase A by uppercase A, except if they are preceded with a space
- Display the initials (first letter and those after a space)
- Display odd letters uppercase and even letter lowercase

The program must display all generated strings.

 Example Code

import java.util.*;
public class Main
{
	static void main(String[] args)
	{
		System.out.print("Tell a string: ");
		String Entry = new Scanner(System.in).nextLine();
		String result;
		result = Entry.replace("a", "A");
		System.out.println(result);
		System.out.println(UppercaseFirst(Entry));

	}
	public static String UppercaseFirst(String s)
	{
		return Character.toUpperCase(s.charAt(0)) + s.substring(1);
	}
}
