Could not find or load main class BubbleSort.class

[blaqkout]

I'm getting Could not find or load main class BubbleSort.class when I try to run java BubbleSort file1.txt

any help would be appreciated.

thanks!

import java.io.*;

public class BubbleSort{
	public static void main(String[] args) throws IOException{
		
		int i, count = 0;
		int[] array = new int[100000];
		File f = new File(args[0]);
		FileReader in = new FileReader(f);
		BufferedReader buf = new BufferedReader(in);
		
		String s = buf.readLine();
		
		while (s!=null){
			array[count] = Integer.parseInt(s);
			s = buf.readLine();
		}
		
		buf.close();
		
		
		System.out.println("Values Before the sort:\n");
		for(i = 0; i < array.length; i++)
			System.out.print( array[i]+"  ");
		System.out.println();
		bubble_srt(array, array.length);
		System.out.print("Values after the sort:\n");
		for(i = 0; i <array.length; i++)
			System.out.print(array[i]+"  ");
		System.out.println();
		System.out.println("PAUSE");
	}

	public static void bubble_srt( int a[], int n ){
		int i, j,t=0;
		for(i = 0; i < n; i++){
			for(j = 1; j < (n-i); j++){
				if(a[j-1] > a[j]){
					t = a[j-1];
					a[j-1]=a[j];
					a[j]=t;
				}
			}
		}
	}
}

How are you running it?
What (full) command are you using?
Where are you running it from?
Where is the BubbleSort class file located?

Have you compiled BubbleSort.java?

I'm running it from the command line;

java BubbleSort smallArray.txt

C:\Users\%username%\workspace\BubbleSort\bin\


I'm using eclipse Indigo to create it. When I run the code in eclipse I get the error even after I config the run to let me choose a file.

Exception in thread "main" java.io.FileNotFoundException: C:\Users\%username% (The system cannot find the file specified)
at java.io.FileInputStream.open(Native Method)
at java.io.FileInputStream.<init>(Unknown Source)
at java.io.FileReader.<init>(Unknown Source)
at BubbleSort.main(BubbleSort.java:16)

Maybe you should enter the full path to the smallArray.txt, because the way you run it the interpreter is trying to locate the file in the running directory!

I just tried it with java BubbleSort "C:\Temp\smallArray.txt" and it at least executed. How can I fix the code to make it so I don't have to have explicit paths to the file?

In Eclipse go Run -> Run Configuration.In the Java Application right click New... and in the arguments tab write the path to the file.
