Issues with ascending number program

[newtojava2011]

I am new to java as the name states. I am attempting a program where you need to input three numbers from a file and list them in ascending order. I need to use if and if else statements only, no arrays. Not sure where I went wrong on it but any help would be great.

import java.io.*;
import java.util.*;
 
public class AscendingOrder
{
 
	public static void main(String[]args) throws FileNotFoundException
	{
		double num1, num2, num3;
 
		Scanner inFile = new Scanner(new FileReader("c:\\numbers.text"));
 
		num1 = inFile.nextDouble();
		num2 = inFile.nextDouble();
		num3 = inFile.nextDouble();
 
		if ((num1 < num2) && (num1 < num3))
		{
			 System.out.print("The numbers in ascending order are: " + num1);
		else if (num2 < num3)
			  	 System.out.println(" " + num2 + " " + num3);
		else
			 System.out.println(" " + num3 + " " + num2);
		}
		if ((num2 < num1) && (num2 < num3))
		{
				  System.out.print("The numbers in ascending order are: " + num2);
		else if (num1 < num3)
			     System.out.println(" " + num1 + " " num3);
		else
			System.out.println(" " + num3 + " " num1);
		}
		if ((num3 < num1) && (num3 < num2))
		{
			System.out.print("The numbers in ascending order are: " + num3);
		else if (num1 < num2)
			     System.out.println(" " + num1 + " " + num2);
		else
		    System.out.println(" " + num2 + " " + num1);
		}
		inFile.close();
	}
}

For future reference, please use [code] tags for code. It is much easier to read.

Your braces for your if statements don't match up. it should look more like this:

if (condition)
{
//code
}
 
else if (condition)
{
//code
}
 
else
{
//code
}

Thanks, and will do next time

Any help would be greatly appreciated

That sounds like an execution error not a compile error.
Please copy and paste here the full text of the error message. The message says what is wrong and where.

That help at all?

[Norm]

java.lang.NoClassDefFoundError: AscendingOrder

That says that the java program did NOT find the class: AscendingOrder

Where is the AscendingOrder.class file?
How are you trying to execute your program?
Are you entering the java command on a command prompt window?

[newtojava2011]

Not sure if this is what your asking for but im using TextPad. Saved as .java but hasn't compiled so it wont save as .class file yet.

[Norm]

Not sure where I went wrong on it

What does this mean?

Are you getting errors from the javac/compiler when it compiles your program?
Or are you having problems executing the javac command? The OS can't find it.

[newtojava2011]

The compiler

[Norm]

The compiler

Yes that is an issue if you don't have one. Do you have one that works for you?

[newtojava2011]

Not sure if I'm understanding you correctly but yes my compiler works fine, this program is just not compiling. Sorry if I seem like an idiot I am new to programming and do not completely understand everything as of yet.

[newtojava2011]

Thanks for the help by the way

[Norm]

this program is just not compiling

Then I would expect the compiler to be outputting error messages.
Copy and paste them here if you want help fixing them or understanding them.

Not sure if this helps but when I try and complile it says under tool output "tool completed with exit code 1"

[Norm]

What are you trying to do with the java command?
Go to this site and read about the java and the javac commands:
Java SE 6 Documentation

[Norm]

it says under tool output

"it"?
Sounds like you need to study how to use your IDE.

[dlorde]

"it"?
Sounds like you need to study how to use your IDE.

From the error output, I suspect it's being run from the command line.

@OP - please post the full text of the command you are using to compile the program, and where the source file is situated.
