Help BubbleSort Array wont run?

Nov 20th, 2006

I'm just learning java and this is my first sort program. I can't get it to run. I sure could use some help.

public class SortCharArray
{
public static void main(String[] args) throws Exception
{
char[] someChars = new char[10];
int x;

for(x = 0; x < someChars.length; ++x)
{
System.out.print("Enter a character ");
someChars[x] = (char)System.in.read();
System.in.read(); System.in.read();

}

System.out.println("Before sort");
for(x = 0; x < someChars.length; ++x)
System.out.print(someChars[x] + " ");

bubbleSort(someChars, someChars.length);

System.out.println("\nAfter sort");
for(x = 0; x < someChars.length; ++x)
System.out.print(someChars[x] + " ");
System.out.println();

}

public static void bubbleSort(char[] array, int len)
{
int a, b;
char temp;
int highSubscript = len - 1;
for(a = 0; a < highSubscript; ++a)
{
for(b = 0; b < highSubscript; ++b)
if(array[b] > array[b = 1])
{
temp = array[b];
array[b] = array[b + 1];
array[b + 1] = temp;
}
}
}

}

Well, supplying the errors you are getting would be helpful.

Please use code tags when posting code. Read the information in the links below.

This is how I code it in c/c++:

{
    for(b = 0; b < highSubscript; ++b)

            {
                temp = array[a];
                array[a] = array[b];
                array[b] = temp;
             }
      }
}
for(a = 0; a < highSubscript-1; ++a)
{
    for(b = 0; b < highSubscript; ++b)
    {
            if(array[a] > array[b])
            {
                temp = array[a];
                array[a] = array[b];
                array[b] = temp;
             }
      }
}
