I have generated many errors in my code for this program but I particularly want to focused on the first error that comes up. Here is the outline of my code:
//a java application that prints the table of pythagorean triples that go up to 500 using a for loop
public class luby{
//main method executes java application
public static void main(String args[]){
//declare variables
for(int side_1=1; int side_1 <=500; side_1++){
for(int side_2=1; int side_2 <=500; side_2++){
[Code] ....
Here is the output of my code when I attempt to compile it:
C:UsersCourtneyDesktopchapter five exercises for javaluby.java:12: error: '.class' expected
for(int side_1=1; int side_1 <=500; side_1++){
^
C:UsersCourtneyDesktopchapter five exercises for javaluby.java:12: error: illegal start of expression
for(int side_1=1; int side_1 <=500; side_1++){
[Code] ....
12 errors
Tool completed with exit code 1
The first error I want to focus on is the class error; I will focus on the remaining errors once this error is resolved
I'm attempting to make a simple Pythagorean Theorem program (A squared + B squared = C squared) but am running into problems when I write it as object oriented. The darn thing works when written as a simple process, but that isn't Java now is it? Here's the simple:
public class PythagoreanTheorem extends ConsoleProgram { public void run() { println ("Finding C from A and B."); double a1 = readDouble("Input A: "); double b1 = readDouble("Input B: "); double aSq = (a1*a1); double bSq = (b1*b1); double cSq = (aSq + bSq); double c = Math.sqrt(cSq); println ("C = " + c);
Basically its a program where a user is prompted to enter the length of all three sides of a triangle and the program calculates the area by herons formula and can tell if the triangle is equilateral or Pythagorean. I am having trouble entering a formula to where all three enter sides cant possibly be a triangle. Here is my Program. Where the '?' is stated.
import java.util.Scanner; public class Triangle { public static void main(String[] args){ double a; double b; double c; double s; double x; double area;
I am trying to print a loop inside an array of a greater size than the loop itself. Like for example I have an array of size 7 but it has only 3 elements.
now what I want to do is print these three numbers in a loop so that my array[3]=2;array[4]=3;array[5]=4 ...... till the last one. Also the array could be any size and not just 7.
Here's the code: it's while loop inside a for loop to determine the proper length of a variable:
for (int i = 0; i < num; i++) { horse[i]=new thoroughbred(); boolean propernamelength = false; while (propernamelength==false){ String name = entry.getUserInput("Enter the name of horse "

I was just wondering what was going on here -- I've initialized the variable, so why do I get this message? (actually the carat was under the variable name inside the parentheses.
I have everything else working. My problem is that when i type "quit" to close the outer loop. It still runs the inner loop. The National Bank manager wants you to code a program that reads each clients charges to their Credit Card account and outputs the average charge per client and the overall average for the total number of clients in the Bank.
Hint: The OUTER LOOP in your program should allow the user the name of the client and end the program when the name entered is QUIT.In addition to the outer loop, you need AN INNER LOOP that will allow the user to input the clients charge to his/her account by entering one charge at a time and end inputting the charges whenever she/he enters -1 for a value. This INNER LOOP will performed the Add for all the charges entered for a client and count the number of charges entered.
After INNER LOOP ends, the program calculates an average for this student. The average is calculated by dividing the Total into the number of charges entered. The program prints the average charge for that client, adds the Total to a GrandTotal, assigns zero to the Total and counter variables before it loops back to get the grade for another client.Use DecimalFormat or NumberFormat to format the numeric output to dollar amounts.
The output of the program should something like this:
John Smith average $850.00 Maria Gonzalez average $90.67 Terry Lucas average $959.00 Mickey Mouse course average $6,050.89 National Bank client average $1,987.67
Code:
public static void main(String[] args) { Scanner scan = new Scanner(System.in); String name = ""; int charge = 0; int count = -1; int total = 1; int grandtotal = 0; int average = 0;
How to convert this program from a while loop to a for loop.
import java.util.Scanner; public class LongDivision { public static void main(String arguments[]){ Scanner input = new Scanner(System.in); System.out.println("Enter the dividend: ");
I am trying to make a program add values from a loop. So what its supposed to do is search through tokens on an imported file. The file lists State, Capital, and then capital population. Then take the population string, turn it into numbers, and then do stuff with the numbers. First I'm supposed to find the Highest and lowest population of the places in the file (which I did without problem), but the finally thing is I'm supposed to add each found population to the last so I can find the average of the populations.
I just cannot seem to grasp how to do that. I THINK I'm supposed to some how store the given value into a variable, but how do I get that variable to add to the new value?
like...? Get token -> a b = a c = a + b
or wait no.....
Java Code :
import java.io.*; import java.util.Scanner; public class CapPopS { public static void main(String[] args) throws IOException { File stateCAP = new File("state-capital-2004population.txt"); if (!stateCAP.exists())
My teacher wants me to make a program that counts the amount of steps a student takes a day. The program asks for other info such as name, age, college. However I need to write a loop that will allow the user to enter how many ever steps they took and convert them to miles.how exactly to make the steps entered by the user within the loop be their own individual days like monday tuesday etc. Like the loop will ask how many steps did you take monday.. tuesday.. etc for each time it runs.
package StudentInfo; import java.util.Scanner; public class studentinfo { public static void main (String [] args){ Scanner scan = new Scanner(System.in);
I need to write a program that measures how long it will take someone to make a million dollars if he is being paid $5.75 an hour, but the pay rate is increase by 0.2% each week after the third week.
This is the first time I've ever gotten an infinite loop with a FOR loop. This program is supposed to let you enter five integer numbers and draw a bar chart based on those numbers. After the fifth number is entered, guess what? It wraps back around to zero again and starts over! Why the bleep doesn't it stop? The code is below:
Create a loop where you add the integers from 1 to 50.
public class Sum50 { public static void main(String[] args) { int sum = 0; int max = 50; for(int i = 0;i <= max; i++){ sum=sum+i; } System.out.println("Sum is " + sum); } }
I'm fairly new to programming, just started yesterday with a book I downloaded of the net. The book comes with a couple of examples on how to code and they all seem to work fine except for this loop.
class fordemo { public static void main(String args[] ) { int count; for(count = 0; count < 5; count = count+1); System.out.println(" This is count: " + count); System.out.println("Your are all done! "); } }
I can't seem to find the problem. All it gives me is, "This is count: 5 You are all done!"
When it's supposed to give me,
"This is count: 1 This is count: 2 This is count: 3 This is count: 4 You are all done!"
Found the error, semicolon after the for loop is not necessary. Should be...
class fordemo { public static void main(String args[] ) { int count; for(count = 0; count < 5; count = count+1) System.out.println(" This is count: " + count); System.out.println("Your are all done! "); } }
I am trying to program a version of the "Worlds Hardest Game" using ready to program and applets for a final class project. Unfortunately I cannot figure out how to get my keylistener to work because I am using a loop for the enemies to go back and forth.
import java.applet.*; import java.awt.*; import java.awt.event.*; public class HardestGame extends Applet implements KeyListener, MouseListener { final int WIDTH = 400; final int HEIGHT = 123; int myX = 400; int myY = 400;
I wrote a program using switchcase.I used do while to show the menu to the user until the user decides to exit the menu.I used try catch to prevent ant exception and it worked properly.But i got one problem.When exception occurs,desired msg is printed but i am unable to display the menu to the user.So user wont be able to continue after an exception is caused.
If I for example choose 8 as "multiplikationstabell" and 4 as "faktor" the whole code works except that "svar" gets printed as 8 in every turn. Why? "Faktor" gets added with 1 every time but "svar" stays at 8.......
import java.util.Scanner; public class Multiplikationstabell { public static void main(String args[]){ Scanner Heltal = new Scanner(System.in);
public static void drawFirstHalf() { for (int line = 1; line <= SIZE; line++) { System.out.print("|"); for (int dots1 = 1; dots1 <= SIZE - line; dots1++) { printDot();
[Code] ....
How would I get rid of the redundancy of the dots1 and roof for loop in the nested for loop? The lines are just repeated and I'm not sure how to get rid of the redundancy.
I am doing a simple program, just to find multiples of 7 all the way to 125. But the loop its not stopping at 125 and is going to 126.
public class Assingment2B { public static void main(String[] args) { int number = 0; while (number <= 125) { number += 7; if (number % 7 == 0) { System.out.println(number);
just trying to learn it on my spare time and I'm doing do-while loops
public class help { public static void main (String args[]) throws java.io.IOException { char choice, ignore; do{ System.out.println ("Choose one:"); System.out.println("1. if"); System.out.println("2.switch");
[code]....
It makes no difference in the program wither i delete this block or keep it..how while (choice < '1'| choice >'2'); translates? I would assume it would be while (choice >= '1'| choice =<'2');?
I need to add a kb.nextLine(); somewhere but I've tried adding it after nextInts and it hasn't worked. The problem is in the test.
public class Account{
//instance variables private static double annualInterestRate;//this is the class variable private int id; private double balance; private java.util.Date dateCreated; //creates an object from the date class in java
I'm developing a Swing Project and I have a textarea in which the item names will be entered separating with commas. The code has to check every element and fetch the price of it and calculate the total amount and display it in the text field. But Somehow it does not enter the while Loop? Why?
Here is the code
String str = accessories.getText(); accessories.setText(str.toUpperCase()); String[] str_arr = accessories.getText().split(","); float t1 = 0; float t2 = 0; for (int i = 0; i < str_arr.length; i++) { System.out.println(str_arr[i]); System.out.println("
