Certainly! Below is a simple Java program that you can use in BlueJ to count the number of words and spaces in a sentence:
public class WordSpaceCounter {
public static void main(String[ ] args) {
Scanner scanner = new Scanner(System.in);
// Input a sentence
System.out.print("Enter a sentence: ");
String sentence = scanner.nextLine();
// Count words and spaces
int wordCount = countWords(sentence);
int spaceCount = countSpaces(sentence);
// Display the results
System.out.println("Number of words: " + wordCount);
System.out.println("Number of spaces: " + spaceCount);
}
// Function to count words
private static int countWords(String sentence) {
String[] words = sentence.split("\\s+");
return words.length;
}
// Function to count spaces
private static int countSpaces(String sentence) {
int spaceCount = 0;
for (char c : sentence.toCharArray()) {
if (Character.isWhitespace(c)) {
spaceCount++;
}
}
return spaceCount;
}
}
Copy and paste this code into BlueJ, compile, and run the program. It will prompt you to enter a sentence and then display the number of words and spaces in that sentence.
