Just simple examples, there are many other ways to read from files you have to search and find what fit wit you.

Write:
CODE
try {
    FileOutputStream fout=new FileOutputStream("C:\\1.out");
    OutputStreamWriter out= new OutputStreamWriter(fout);
        
    out.write("1212313121\n");//move to the next line
    out.write("1212313121\t");//make a tab
    out.close();
} catch (FileNotFoundException e) {
    e.printStackTrace();
} catch (IOException e) {
    e.printStackTrace();
}


Read:
CODE
try {
    FileInputStream fin = new FileInputStream("C:\\1.out");
    InputStreamReader in= new InputStreamReader(fin);

    System.out.print((char)in.read());
    in.close();
} catch (FileNotFoundException e) {
    e.printStackTrace();
} catch (IOException e) {
    e.printStackTrace();
}

Please use google for such common questions.
There are very good examples here. (and some more in the nio package)
Also, please not that asking for urgent replies won't make answering any faster. If we know the answer, we'll answer, sooner or later, when we have time to do so.
