Can somebdoy explain the output for this program?
Why is the value in the following program being read as 255 instead of -1 ?
The intent behind this program was to check whether the FileInputStream would be able to read -1 from the file, which btw is also the return value of read() when EOF is reached.
import java.io.IOException;
import java.io.FileInputStream;
import java.io.FileOutputStream;
class TestFileInputOutputStream
{
public static void main(String[] args) throws Exception
{
FileOutputStream fos = new FileOutputStream (" testfos.txt");
FileInputStream fis = new FileInputStream (" testfos.txt");
try
{
for (int i=0;i<10 ;i++ )
{
fos.write((byte)-1);//writing -1
}
int c ;
while ( (c=fis.read()) != -1)
{
System.out.print(c);//prints 255
}
}
finally
{
if (fos!= null)
{
fos.close();
}
if (fis!= null)
{
fis.close();
}
}//finally
}
}
