omg lol i just found out that the problem was that java didn’t like my naming my object c1 so i changed it to combo and now it works thx for your time anyways…

java ignore case problem?
I’m trying to ignore when the user inputs uppercase letters and I tried out my code by typing a word into the program with uppercase but it doesnt convert it and it just goes to my message saying “please enter the word correctly”
can anyone help me with this
import java.util.*;
public class sport
{
static Scanner console = new Scanner(System.in);
public static void main(String[] args)
{
double quantity; // Declare variables
double setup;
int demand;
double inventory;
String products;
System.out.println(“Welcome to the sport program.”);
System.out.println();
System.out.println(“Please enter the sport name: “);
products = console.next();
if (products.equalsIgnoreCase(“football”)){
String products = products.toLowercase;
System.out.println(“Input the demand rate: “);
}
else
System.out.println(“You entered ” + products);
System.out.println(“Please enter the product name correctly!”);
}
}
Best answer:
You have several problems:
1) String products = products.toLowercase;
This is wrong, you do not use “String” again, you already declared the variable ‘products’ above. Now your simply trying to do an assignment, it should be :
products = products.toLowerCase();
2) “toLowercase” needs to be capitalized & needs parentheses () because its a method.
use “.toLowerCase()” instead.
3) Lastly you need to use brackets{} around your if/else statement if its more than 1 line.
if ( products.equalsIgnoreCase(“football”) )
{
String products = products.toLowercase;
System.out.println(“Input the demand rate: “);
}//end if
else
{
System.out.println(“You entered ” + products);
System.out.println(“Please enter the product name correctly!”);
} //end else
Otherwise
System.out.println(“Please enter the product name correctly!”);
will execute every single time…. Good Luck

Using Java to print a rectangular pattern (please check if my code is right)?
/* Program Statement:
* This program will print a filled rectangular pattern using the character c, that is
* width characters wide, and height characters high.
ex. width input is 5, height input is 3. output is:
ccccc
ccccc
ccccc
*/
import java.util.*;
public class RectangularCPattern
{
public static void main(String[] args) // Main method
{
printRect(c,width,height);
}
public static void printRect(char c, int width, int height)
{
Scanner get = new Scanner(System.in);
width=get.nextInt();
height=get.nextInt();
for (c=0; width>c; c++)
{
System.out.print(“c”);
System.out.println();
for (c=0; height>c; c++)
{
System.out.println(“c”);
}
}
} //end method printRect
}//end main
I don’t know why i keep getting these errors:
cannot find symbol
symbol : variable c
location: class RectangularCPattern
cannot find symbol
symbol : variable width
location: class RectangularCPattern
cannot find symbol
symbol : variable height
location: class RectangularCPattern
we have to use another method (our assignment is based on it) and the problem occured where u said it was
printRect(c,width,height);
from the main
Best answer:
c, width, and height are not declared in your main. Another suggestion that I would make is to simplify your code and not pass things to another method. Instead, simply contain it all in your main.
public static void main(String[] args)
{
int height;
int width;
Scanner input = new Scanner(System.in);
height = input.nextInt();
width = input.nextInt();
for (int i=0; i
{
for (int j=0; j
{
System.out.print("C");
}
System.out.println();
}

Help with java classes!! I cannot make my program work!!!?
Here’s the class I want to make:
import java.util.*;
public class ClaseFecha {
//declaracion de variables
String dia, mes;
public void SetDia(String d)
{
dia=d;
}
public String getDia() {
return dia;
}
public void setMes(String m) {
mes=m;
}
public String getMes() {
return mes;
}
public String toString() {
return dia+”-”+mes;
}
}
Here is the main:
import java.util.*;
public class Fecha {
public static Scanner tecla=new Scanner(System.in);
public static void main(String[] args) {
//Crea el objeto con el metodo constructor.
Fecha f=new Fecha();
String d,m;
m=”0″;
d=”0″;
d.setDia(“06″);
m.setMes(“10″);
System.out.println(“La fecha de hoy es: “+f.toString());
//modificar
System.out.print(“Qué día es hoy (dd)”);
d=tecla.nextLine();
d.setDia(d);
System.out.print(“Qué mes es hoy (mm)”);
m=tecla.nextLine();
m.setMes(m);
System.out.println(“Tu Fecha modificada: “+f.toString());
}
}
I get this errors:

^
Fecha.java:29: cannot find symbol

location: class java.lang.String
m.setMes(m);
^
4 errors
Best answer:
You are declaring d and m as Strings and start by setting them equal to “0″. That is fine. But then you are trying to use methods as if they were ClaseFecha objects. If you want to use the setDia, getDia, setMes, getMes methods, you need to declare d and m as new ClaseFecha objects. Also, when you do that, you will not be able to use the d = “0″ and m = “0″ statements. But that is what the setDia and setMes methods are for, if I understand your code.
Your errors are because you are declaring variables as one type, but trying to use methods as if they were a different object type.

Why can I not use variables in Java?
I tried some fairly simple code:
import java.util.*;
//import java.util.Scanner;

public class ZellersCongruence {
public static void main(String args[]){
int DayOfWeek;
int DayOfMonth;

System.out.println(“Please enter the day of the month”);
DayOfMonth = in.nextLine();
System.out.println(“Please enter number of the month”);
Month = in.nextLine();
System.out.println(“Please enter the year”);
YearOfCentury = in.nextLine();
And Command Prompt keeps spitting out:

Any idea why this keeps happening? If you need the rest of the code then I can provide it :)
Thanks for reading :)
Thanks for the help, I was just pasting that bit from old code. However there’s a new problem, to do with incompatible types, something about expecting an integer :S

Best answer:
It’s not working because your variable (‘in’) doesn’t exist. You didn’t declare it anywhere.
Also, you commented out a few imports that are used in the program.

Java Barcode Scanner + Drivers?
Hi there! I need to buy a Barcode scanner (similar to the ones you get in supermarkets) and the drivers. I need to also be able to program it in Java with the 1.6 JDK. It would also be good if it worked on mac. I am in the UK. Thanks!
Best answer:
I played around a bit with an OpenSource project called Barbecue. Bear in mind there are different kinds of barcodes, but, Barbecue does generate the same bar code the mobile phones over in Europe can read. I know that much.

Can anyone see the problem?
Thanks,

Best answer:
There is a problem with this section:
while(CustomerName[k]!=null)
for( k=4;l<10;k++) <--- what is 'l', k might increase infinitely and make outofbound error
{if(customerName[k]==null) break;
System.out.println("Seat Number : " + k + "Name: " + customerName[i]); } <-- here is your error, 'i' is out of scope

I am a beginner in java programming, and I have a simpler way of doing Java Sequential Search or Java Linear Search, if that is what you want. Here it is:
import java.io.*;
public class linear_search
{
public static void main (String args[]) throws IOException
{
BufferedReader std = new BufferedReader (new InputStreamReader (System.in));
System.out.println (“Input the array elements: “);
int a[] = new int [10];
int i, flag = 0;
for (i = 0; i
{
a[i] = Integer.parseInt (std.readLine());
}
System.out.println ("Enter the number to be searched: ");
int ns = Integer.parseInt (std.readLine());
{
for (i = 0; i
{
if (ns == a[i])
{
flag = 1;
break;
}
}
if (flag == 1)
{
System.out.println ("Number found! ");
}
else
System.out.println ("Number not found! ");
}
}

JAVA Trying to .replace the escape character ‘\’ with “\” for an absolute path.?
But it is not working. Here is my code
Scanner textReader = new Scanner(InputFile);
String testx = textReader.nextLine();
System.out.println(testx);
testx = testx.replace(‘\’, (char) (‘\’ + ‘\’));
System.out.println(testx);
I have also tried adding up the ASCII characters in the char typecast but at some point it just gives me the question mark symbol no matter how high I go. I know there is a way to do this I am just not experienced enough.
I am trying to replace something like C:\SDIDOCS\DMADMIN\@q#01!.TIF with C:\SDIDOCS\DMADMIN\@q#01!.TIF for well over 5000 entries in a text file. I refuse to do this manually. Help?
