Program: Write programs that read a line of input as a string and input
Part a) Only the uppercase letters in the string.
Part b) The string, with all vowels replaced by an underscore.
Part c) The positions of all vowels in the string
import java.util.Scanner;
public class Lab5
{
public static void main(String []arg)
{
Scanner input = new Scanner(System.in);
System.out.println("Type a word and press Enter to be reversed:");
String s = input.nextLine();
System.out.println("You typed: "+ s);
PLEASE make sure it compiles and write the full program to receive full credit. Thank you so much for your help.
