import java.util.Scanner;

public class U2_L3_Activity_Four {

public static void main(String[] args) {

Scanner scan = new Scanner(System.in);

System.out.println("Enter a sentence.");

String sent = scan.nextLine();

int count = 0;

for (int i = 0; i < sent.length(); i++){

char c = sent.charAt(i);

if (c != ' '){

count++;

}

else{

break;

}

System.out.println("The first word is " + count +" letters long");

}

We check to see when the first space occurs in our string and we add one to our count variable for every letter before that. I hope this helps!

Does the submission include the file "SuperPower.java"? Does the file include a public class called "SuperPower"? Does the class

Oduvanchick [21]

Answer:

Here is the program fulfilling all the requirements given:

import javax.swing.JOptionPane;

public class SuperPower{

public static void main(String[] args) {

String power;

power = JOptionPane.showInputDialog("What is your super power?");

power = power.toUpperCase();

JOptionPane.showMessageDialog(null, power);} }

Explanation:

Does the file include a public class called "SuperPower"

See the statement:

public class SuperPower

Does the class include a public method called "main"? Is the "main" method static?

See the statement:

public static void main(String[] args)

Does the main method have a String assignment statement that uses "JOptionPane.showInputDialog"

See the statement:

power = JOptionPane.showInputDialog("What is your super power?");

Does the main method have a statement that uses "JOptionPane.showMessageDialog"?

See the statement:

JOptionPane.showMessageDialog(null, power);

Does the program convert the String from "JOptionPane.showInputDialog" using the "toUpperCase" method?

See the statement:

power = power.toUpperCase();

Does the submission include a screenshot that shows an Input dialog that asks, "What is your superpower?" Does the submission include a screenshot that shows a Message dialog stating " TO THE RESCUE!", where "" is the input converted to upper case?

See the attached screenshots

If the program does not let you enter an exclamation mark after "to the rescue" then you can alter the code as follows:

import javax.swing.JOptionPane;

public class SuperPower{

public static void main(String[] args) {

String power;

power = JOptionPane.showInputDialog("What is your super power?");

power = power.toUpperCase();

JOptionPane.showMessageDialog( null, power+"!");} } // here just add an exclamation mark which will add ! after the string stored in power
