any one have any idea?

[imorio]

Yes, I have plenty of ideas.

Your need is noted.

Any more questions?

Hello

I tried to implement a bucket sort program using 2D array:


I modify it more:

/*

* and open the template in the editor.
*/

package assignment3;

/**
*

*/
public class mybookbucketsort {


public static int[] bucketsort(int [] A, int c){

int rows=A.length;
int [] bucket=new int [5];
int columns= bucket.length;
int [][] B= new int [rows][columns];

for( int i=0 ; i<rows-1 ; i ++){
for( i=1 ; i<columns ; i ++){

B[rows][columns]=0;
}
}
for (int i=0; i<A.length; i++){
// B[A[i]]++;
int t = (int) Math.floor(rows*A[i]);
B[rows][columns] = A[t];
}



// ====== insertion sort

for ( int i=0 ; i< B.length ; i++){

int key;
for (int j = 1; j < c; j++)
{
key = B[rows][columns];
i = j - 1;
while (i >= 0 && B[rows][columns] > key)
{
B[i + 1] = B[i];
i = i - 1;
B[rows][columns] = key;
}
}
}

return A;
}

public static void main(String[] args) {

int [] A = { 1,3,4,5};
bucketsort(A, 3);
System.out.println();
}
}

It's very important that you ask specific questions. Vague questions like "Here is my code, help" will not receive great attention..as you have seen. What is your problem? What doesn't work? How does it not work? What have you done to try to fix it? What does it produce? What were you expecting? Does it compile? If not, what compilation errors did you get(copy/paste EXACT errors, not paraphrasing)? What do you think they mean? What do you think can be done to fix the errors?

A lot of people here are not going to scan your code and give you the answer unless you put in the effort.
