Answer:
The Java code is given below with appropriate comments
Explanation:
//Program
//Import the necessary libraries
import java.util.Scanner;
//Define the class
public class CountStringCharacters
{
//Start the main method
public static void main(String[] args)
{
//Prompt the user to enter the input line
Scanner scan = new Scanner(System.in);
System.out.println("Enter a sentence or phrase: ");
String s = scan.nextLine();
//Take the number of characters and keep the count
int numOfCharacters = getNumOfCharacters(s);
System.out.println("You entered: "+s);
System.out.println("Number of characters: "+numOfCharacters);
//Call the method outputWithoutWhitespace
outputWithoutWhitespace(s);
}
//The method getNumOfCharacters
public static int getNumOfCharacters(String s)
{
int numOfCharCount = 0;
for(int i=0; i<s.length();i++)
{
numOfCharCount++;
}
return numOfCharCount;
}
//Definition of the method outputWithoutspace
public static void outputWithoutWhitespace(String s)
{
String str = "";
for(int i=0; i<s.length();i++)
{
char ch = s.charAt(i);
if(ch != ' ' && ch != '\t')
str = str + ch;
}
System.out.println("String with no whitespace: "+str);
}
}
