Explanation / Answer

import java.util.Scanner;
public class Main
{
private static Scanner scnr = new Scanner(System.in);

private static String text;
public static void main(String[] args)
{
System.out.println("Enter a sentence or phrase: ");

text=scnr.nextLine();
  
System.out.println("You entered: "+ text);
  
int count=getNumOfCharacters(text);
System.out.println();
System.out.println("Number of characters: " + count);
String modifiedstring = outputWithoutWhitespace();
System.out.println("String with no whitespace: " + modifiedstring);

}

private static String outputWithoutWhitespace()
{
text=text.trim().replaceAll(" ","");
return text;
}

private static int getNumOfCharacters(String t)
{
int count = 0;
for (char letter : t.toCharArray()){
count++;

}
return count;
}
}

/*SAMPLE output
Enter a sentence or phrase:
The only thing we have to fear is fear itself.
