Converting 1-dimensional array to 2-dimensional array
 
Hello,

I was wondering if someone can help me figure out the issue that I cannot seem to get around. I have been attempting to convert a 1-Dimensional array to a 2-Dimensional array (also called a matrix), but just cannot figure out how to do it. Here are the parameters:

--- I have a 1-Dimensional array of characters that has length 36,
called array1. The array is:
abcdefghijklmnopqrstuvwxyz0123456789

--- The 2-Dimensional array, called matrix, is 6x6, so it is square and can
hold all the 36 characters from array1.

What I want to do is convert the array1 to matrix starting with the upper right corner. An example of this would be:
:
              a  ---->    ba  ---->    dba  --->    gdba
                          c            ec            hec
                                        f            if
and so on untill all 36 characters are inserted into the matrix.

If anyone can help me I would really appreciate it.

Thankz,

Tazz

I know, i'm slow .. but i haven't got the time to think about it. Here it is:
:

import java.io.*;

class matrix {
        public static void main(String args[]){
                BufferedReader in=new BufferedReader(new InputStreamReader(System.in));
               
                int n=3;


                int a[][]=new int[3][3];
                int i=0;  //row
                int j=0;  //colomn
                int step=1; // used when under the main diagonal
                int pas=0;  // used when above the main diagonal
               

                for(;;){
                        if(pas<=n-1){
                                i=0;
                                j=n-1-pas;

                                do{
                                        try{
                                                String s=in.readLine();
                                                int x=Integer.parseInt(s);
                              //see if the index is working
                                                System.out.println("i="+i+" "+"j="+j);

                                                a[i][j]=x;
                                                i++;
                                                j++;
                                                }
                                        catch(IOException e){e.printStackTrace();}
                                }while(i<=pas);
                                pas++;
                        }

                        if(pas>n-1){
                                i=step;
                                j=0;

                                do{
                                        try{
                                                String s=in.readLine();
                                                int x=Integer.parseInt(s);
                              //see if the index is working
                                        System.out.println("i="+i+" "+"j="+j);
                                        a[i][j]=x;
                                        i++;
                                        j++;

                                        }catch(IOException e){e.printStackTrace();}
                                }while(i<=n-1);
                                step++;
                        }
                if((step>n-1))break;
                }
//see if it worked :)
        for(i=0;i<n;i++){
                for(j=0;j<n;j++){
                        System.out.print(a[i][j]);}
        System.out.println();}
}
}
