Convert the input into square yards

pjpav · #1 23-Sep-2005, 19:36

Since I was a bit vague the last time, here is my program which is suppossed to apply a discount based on square yards of carpet purchased at twenty dollars a square foot.The program is suppossed to convert the input into square yards and perform various operations. Will someone who knows what they are doing take a look at this and tell me what I am doing wrong? It would be greatly appreciated, PAY IT FORWARD!

JAVA Code:

 import java.util.Scanner;
    public class CarpetSale
   {
       public static void main(String[] args)
      {
     String units;
     
     
     
      double length, width;
      double squareYard;
      double inch, in, inches;
      double feet, ft, foot;
      int area;
    double squareFoot;
     double squareInch;
    
     inch = ft % 12;
       yard = ft * 3;
      ft = inch * 12;
      in = foot % 12;
       length = feet + inches;
       width = feet + inches; 
       area = length * width;
       squareInch = inch * 12;
        
       squareFoot = squareInch * 144;
         squareYard = squareFoot * 9;

      	
      	
      	
 
           
     
     
     
           double measurement;
      
      
      {
      Scanner scan = new Scanner( System.in );
     
     char measurement;
      
      
      
         System.out.print("Enter the length of your measurement in feet or inches:")
         int length = scan.nextInt();
         
      		while(true){ 
         
      	measurement = getDouble();
      	
      	if (measurement == 0)
      	break; 
      	
      	units = feet;            
            units = inches;




if (units.equals("inch") || units.equals("inches") 
                                            || units.equals("in")) {
                inches = measurement;
            }
			
				else if (units.equals("foot") || units.equals("feet") 
                                            || units.equals("ft")) {
                inches = measurement * 12;
            }



      	
      	
      		/* Get the user's input, and convert units to lower case. */
           
         	
      		
      		
      		System.out.print ("That is equivalent to:" + measurement);
         
      	
      
      	
      	
      	int measurement = scan.nextInt();
          Scanner scan = new Scanner( System.in );
      char measurement

      	
          System.out.print("Enter the width of your measurement in feet and inches:");
         int second = Integer.parseInt(secondString);
         int measurement + second = total price;
         int total price = w
         
         int totalMeasurement = length * width;
        
        int totalMeasurement = x
        if ( x < 10 );
         Scanner scan = new Scanner( System.in );
      char measurement

        
         System.out.print (" Your total price is:" w + x * 20);
        int total price 
         Scanner scan = new Scanner( System.in );
      char measurement;


        
        if ( x > 10 || x < 20)
         System.out.print ( " Your cost for the carpet is:" x * 20);
      		String s = new String ( " Your discount is 10%:"(x * 20 * .10 );
      		double y = (x * 20 * .10)
      		Scanner scan = new Scanner( System.in );
      char measurement;

      	 System.out.print ( "Your total cost for the carpet is:" ( x * 20 - y)         
         System.out.print( " You saved:" + y)
        
        if ( x > 20 || x < 30) 
        System.out.print ( " Your cost for the carpet is:" x * 20);
        		String s = new String ( " Your discount is 15%:" (x * 20 * .15 )
      		double y = ( x * 20 * .15)
      		System.out.print ( "Your total cost for the carpet is:" ( x * 20 - y)
      		System.out.print( " You saved:" + y)
      	
      if (x > 30) 
      System.out.print ( " Your cost for the carpet is:" (x * 20)
      	String s = new String ( " Your discount is 20%:" (x * 20 * .20)
      	double y =  (x * 20 * .20)
      	System.out.print ( "Your total cost for the carpet is:" ( x * 20 - y) 	 
           	System.out.print( "You saved:" = y)
           System.out.print ( " Can I help you with anything else today?"
         System.exit(0);
      }
   }

}

I TRIED THIS PROGRAM ALSO

JAVA Code:

import java.util.Scanner;
    public class CarpetDiscount
   {
       public static void main(String[] args)
      {

double measurement;

string units; 

double feet, inches, length, width, square_yards, square_foot;

Scanner scan = new Scanner ( System.in );

 System.out.print( "Enter the length of the room in feet and inches, you could use abbreviations:");

while (true) {

/* get the users input and convert units to lower case */

length = getDouble();
measurement = TextIO.getDouble();

if (length == 0)
break; //terminate the loop

units = TextIO.getlnWord();            
           
 units = units.toLowerCase();
 
 /* Convert the input measurement to square yards. */
 
feet = inches / 12;
inches = feet / 36;
yard = (feet *3) == (inches * 36);
square_foot = 9 * feet;
square_yards = 9 * square_feet;

/* Output measurement in terms of each unit of measure. */


           
         
        



           
System.out.print("Thats equivalent to:" + square_yards);

String secondString = JOptionPane.showInputDialog( "Enter the width of the room in feet and inches, you could use abbreviations:");

while (true) {

/* get the users input and convert units to lower case */

length = getDouble();
measurement = TextIO.getDouble();

if (length == 0)
break; //terminate the loop

units = TextIO.getlnWord();            
           
 units = units.toLowerCase();
 
 /* Convert the input measurement to square yards. */
 
feet = inches / 12;
inches = feet / 36;
yard = (feet *3) == (inches * 36);
square_foot = 9 * feet;
square_yards = 9 * square_feet;

/* Output measurement in terms of each unit of measure. */
            
JOptionPane.showMessageDialog(null,"Thats equivalent to:" + square_yards);

            
} // end while loop

hi pjpav,

You should make the following changes in your CarpetSale program:

1. You cannot use spaces(blank characters) in your variable names.
You should use underscore(_) instead.
so correct the corresponding variables by using _ instead of space.

2.You typed these at once you declared the variables. In java the variables are assigned to 0 default. so these code have no effect. You have to enter these code only after you know all the values of the variables to the right.

JAVA Code:

     inch = ft % 12;
       yard = ft * 3;
      ft = inch * 12;
      in = foot % 12;
       length = feet + inches;
       width = feet + inches; 
       area = length * width;
       squareInch = inch * 12;
        
       squareFoot = squareInch * 144;
         squareYard = squareFoot * 9;

3. You missed out a semicolon in numerous occasions. Please correct those errors.

4. You missed out a comma in the System.out.println statements.
for example in line 115,

JAVA Code:

System.out.print ( " Your cost for the carpet is:" x * 20);

you should insert comma between you " and *.
ie your statement should be like this:

JAVA Code:

System.out.print ( " Your cost for the carpet is:" ,x * 20);

5. You can never declare like this:

JAVA Code:

int measurement + second = total price;

if you want a new variable called total_price(and not total price), then declare like this:

JAVA Code:

int total_price = measurement + second;

6.You have initialized the measurement variable of type char in numerous occasions. it should be done only once. remove the extra

JAVA Code:

char measurement

s.

7. You cannot use the measurement variables of type int and char at the same time.

JAVA Code:

int measurement;

JAVA Code:

char measurement;

so change the name of any one of those variables.

8. You have complicated the program very much. try to simplify your program.

In your CarpetDiscount.java:

1.You didnt include the header files to use JOptionPane, getDouble() and getlnWord().

2.You didnt declare many of your variables.

bye,
Paramesh.
