Your Grade

B-   You asked for it! ;-)

Here's my version (note the use of constants, StringBuffer instead of String and especially the fact that this method returns the correct number of characters (compare the size of your resulting String to the size of the original file)):

static String getTextOfFile( String filename ) throws IOException
{  
    StringBuffer text = new StringBuffer();
    int b, count = 0;
    final int MAX_LEN = 255;
    final int LINEFEED = 10;
    char[] ch = new char[MAX_LEN];
    
    InputStream in = new FileInputStream( filename );
    b = in.read();
    while( b != -1 ) 
    {
        if( b == LINEFEED || count == MAX_LEN)
        {
            text.append( ch, 0, count );
            if( count != MAX_LEN )
                text.append("\n");
            count=0;
       }
       else 
       {
            ch[count]=(char)b;
            count++;
       }
       b = in.read();
    }   
    in.close();
    return text.toString();
}
