Chapter 6, Problem 5PE
Explanation of Solution
Program:
File name: “Perfect.java”
//Import necessary header files
import java.util.*;
//Define a class named Perfect
public class Perfect
{
//Define main method
public static void main(String args[])
{
//Declare a variable
int i;
//Print the message
System.out.println("The perfect numbers in the range 1 to 1000 are:");
//For loop to print the perfect numbers between 1 and 1000
for(i = 1; i <= 1000; i++)
{
//Declare variables and initialize the value
int sum = 0, j;
//For loop is executed until the value of j exceeds i
for(j = 1; j < i; j++)

Write an application that accepts a word from a user and converts it to Pig Latin. If a word starts with a consonant, the Pig Latin version removes all consonants from the beginning of the word and places them at the end, followed by ay.
For example, cricket becomes icketcray. If a word starts with a vowel, the Pig Latin version is the original word with ay added to the end. For example, apple becomes appleay. If y is the first letter in a word, it is treated as a consonant; otherwise, it is treated as a vowel. For example, young becomes oungyay, but system becomes ystemsay. For this program, assume that the user will enter only a single word consisting of all lowercase letters.

Write Java code
import java.util.*;
public class PigLatin {
public static void main(String[] args) {
// Write your code here
}
public static boolean isVowel(char c) {
// Write your code here
}
}
This is the question:
Write an application that displays every perfect number from 1 through 1,000. A perfect number is one that equals the sum of all the numbers that divide evenly into it. For example, 6 is perfect because 1, 2, and 3 divide evenly into it, and their sum is 6; however, 12 is not a perfect number because 1, 2, 3, 4, and 6 divide evenly into it, and their sum is greater than 12.
This is the code given:
public class Perfect {
public static void main (String args[]) {
// Write your code here
}
public static boolean perfect(int n) {
// Write your code here
}
}

- This is the question - Write an application that counts the total number of spaces contained in a quote entered by the user. This is the code I have. The issue it seems to be counting like: "The number of spaces is 0 The number of spaces is 0 The number of spaces is 0 The number of spaces is 1 The number of spaces is 1 The number of spaces is 1", rather than just saying it once with the final number of spaces. This is my code - import java.util.*; public class CountSpaces2 { public static void main(String[] args) { // Write your code here Scanner input = new Scanner(System.in); int i; String quote; System.out.println("Please enter your quote "); quote = input.nextLine(); int numSpaces=0; for(i=0; i<quote.length();i++) { char ch=quote.charAt(i); if(ch == ' ') numSpaces++; System.out.println("The number of spaces is " +numSpaces); } } }arrow_forwardWrite a java application for Limpopo’s Car Care Shop that shows a user a list of available services: oil change, tire rotation, battery check, or brake inspection.
