'else' without 'if'

[J Morberg]

Hello. I'm compiling my first program which

accepts 3 numbers from the user

sorts ascending

prints 3 numbers in ascending order

I am having a problem with my if/else statements
==============================
"'else' without 'if'"
------------------------------
else if (y > z); on line 28
and
else if (x > y); on line 33
------------------------------
==============================
here is the code:

import java.io.*;
public class Sort
{
public static void main(String[] args) throws IOException
{
String numStr; //holds an input string
int x = 0;  //User first input value
int y = 0;  //User second input value
int z = 0;  //User third input value
int t = 0;  //temp swap variable
BufferedReader dataIn = new BufferedReader(new InputStreamReader(System.in));  
System.out.println("Enter first number:"); //Prompt the user for the first input number
numStr = dataIn.readLine(); //Get the first number in a String form
x = Integer.parseInt(numStr); //Convert the first number to an Integer 
System.out.println("Enter second number:");
numStr = dataIn.readLine();
y = Integer.parseInt(numStr);
System.out.println("Enter third number:");
numStr = dataIn.readLine();
z = Integer.parseInt(numStr);
// Insert Your Logic to Sort them
if (x > y);
{
t = x;
x = y;
y = t;
else if (y > z);
 {
t = y;
y = z;
z = t;
     else if (x > y);
{
t = x;
x = y;
y = t;
}
}
}
System.out.println("The numbers in order are:");
System.out.println((x) + (y) + (z));

// Print out the three numbers in ascending order

}
}

This is my first program, so obviously I don't know exactly what I am doing. Any help would be appreciated.
Thank you so much,
JM

Remove the semi-colon from your if and else if statements. Here's the proper syntax for an if statement

if(a<b)
{
  //code here
}
else if(a==b)
{
  code here
}

Also, you are missing the closing braces for the if block and for the else if block. Use the example above to see where the closing braces should go.
Keep coding!

Layne and Chad,
Thank you both for your help. Your suggestions quickly fixed my problem.
The code compiled w/out error...but now it wont execute!
When trying to run my "Sort.class" file, I receive the following error:
=================================
Exception in thread "main" java.lang.NoClassDefFoundError: Sort
=================================
Hopefully this one is equally as simple to fix!
Thanks again ~ JM

the code runs fine for me..are u using the following command??

java Sort

Rajeshwari,
Thank you for checking the code out. Yes, I am using the right command.
I believe I might have some classpath or something set up wrong. I am going to investigate that!

I keep getting the error
------------------------------------
Exception in thread "main" Java.lang.NoClassDefFoundError: Sort
------------------------------------
my classpath is set to include the directory for my sdk installation; a QTJava.zip file residing in a j2rel.4.0 directory; and a servlet.jar file within a tomcat directory I've installed to run the server.
As long as one of the classpath entries is set to the "j2sdk1.4.1_01" directory I should be fine, right?
Does it seem that a missmatch in my classpath could create such a problem?
Thanks.../JM
============
oh, by the way...if it worked for you, then I feel much more confident that it's just a setting on my machine that is causing the problem. I will research and find out how to fix it. Thanks again for checking it!
Take care/JM

From which directory are u running the program?
U shud be running the java class from the directory in which the .class file is created.
If u are running from jdk1.4\bin or any other folder then the directory containing the class file must be included in the classpath.
If sample is the name of the directory containing Sort.class then give the following command..

set classpath=Drive:\sample;%classpath%

and then run ur program.
