BufferedReader bufRdr = new BufferedReader(new FileReader(file));

//read each line of text file
while((line = bufRdr.readLine()) != null && row < data.length)
{
StringTokenizer st = new StringTokenizer(line," ");
while (st.hasMoreTokens())
{
//get next token and store it in the array
data[col][row] = Double.parseDouble(st.nextToken());
col++;
}
col=0;
}
row++;
for(row = 0; row<data.length; row++){
for(col = 0; col<data.length; col++){
System.out.print(" "+data[86][1]);
}
System.out.println();
}
}
}
它給像0.0 0.0 0.0 0.0 輸出請幫我打印數組形式的文件
