Reading Files

Java has so many streams to use im lost

I need to read a text file into a variable so far ive got this

Code:



InputStream fis = new FileInputStream(f); 

while ((x = fis.read())!= -1) {
            System.out.print(x); 
            }

This outputs binary data, how do i get acsii data into a Srting variable

Is this the best method for reading text files on windows

binary data==ascii data.

Code:

InputStream fis = new FileInputStream(f); 

while ((x = fis.read())!= -1) {
            s=new String(x); 
                        if (s.equals("your-data-here")) {
                                 (do processing.....)
                        }
            }

does this help?

anyway, not sure 100% but there should be a StringStream() - is there? (i am not a java pro......) but i am sure there is a LineReader() class that you should have a look at

Its not what i wanted

Code:



s = new String(x);

This line causes an error because x is binary data

I need the binary data converted to acsii

would using java.lang.Byte help?

then you could just say:

Byte.toString(x);

InputStream fis = new FileInputStream(f);

String data = "";

do{
i = fis.read();
if (i != -1) data = data + (char)i;
}while(i != -1);

System.out.println(data);

this will append all values from the file to variable data...

Why not do this,

BufferedReader buf = new BufferedReader(new FileReader(f));

System.out.println("buf.ReadLine);
