Answer:
Explanation:
The following code is written in Java. It asks the user for an input and saves it in a String variable. Then it loops through all the characters in the string and counts the spaces. Finally, it prints the total number of spaces in the String.
public static void main(String[] args) {
Scanner in = new Scanner(System.in);
System.out.println("Enter Line Now:");
String userInput = in.nextLine();
int spaceCount = 0;
for (int x = 0; x < userInput.length(); x++) {
if (userInput.charAt(x) == ' ') {
spaceCount++;
}
}
System.out.println(spaceCount);
}
Answer
File names should describe the content of the file.
Explanation
File names are set of words which are used to uniquely identify computer files which are stored in a file system. This helps one to know the contents of the file which you want to find. When you name these file names you use necessary characters you use descriptive words so that you dont have hard times when searching for them. The naming also is determined by the file system you are using because different systems impose different restrictions on the length of the file names and the allowed characters within file names.

Answer:
import java.util.Scanner;
public class StoreGuesses {
public static void main (String [] args) {
Scanner scnr = new Scanner(System.in);
final int NUM_GUESSES = 3;
int[] userGuesses = new int[NUM_GUESSES];
int i = 0;
for (i = 0; i < NUM_GUESSES; ++i){
userGuesses[i] = scnr.nextInt();
}
for (i = 0; i < NUM_GUESSES; ++i){
System.out.print(userGuesses[i] + " ");
}
}
}
/*
Output:
2 4 6
2 4 6
