java output multiple lines to file

tw0nk

hi , im tryin to output a lot of text that i want hardcoded in my program to a file, eg


FileOutputStream out; // declare a file output object
PrintStream p; // declare a print stream object

try
{
// Create a new file output stream
// connected to "myfile.txt"
out = new FileOutputStream("myfile.txt");

// Connect print stream to the output stream
p = new PrintStream( out );


///////////////////////////here is problem...////////////////////////////////////
p.println ("text text text text
text text text text
text text text text
text text text text
text text text text
");

p.close();
}
catch (Exception e)
{
System.err.println ("Error writing to file");
}



but obviously i cant do that, does anyone know the syntax for allowing multiple lines of text to be outputted to a file?

You could write the text to a StringBuffer. That would work I think

e.g.

x = new StringBuffer()
x.append("text text text text
text text text text
text text text text
text text text text
text text text text
");

Can't remember how you output that (my Java's a bit rusty ) but you should find stuff in the API or on Java.sun.com forums

eeep , nope that didnt work , it still looks for the quotation marks at the end of the line , i have looked on java.sun.com for ages and in the API's and i cant seem to find a solution, i know it must be fairly simple but i just cant find the syntax, thanks for your help anyways auburn

I don't get it ?

What's the problem ?

Can't you just put it all on 1 line and put a \nbetween them for the newlines :

p.println ("text text text text\ntext text text text\ntext text text text\ntext text text text\ntext text text text");

Are you getting a compile error or what ?

As dealock says, the compiler ignores when you go onto a new line in your program.

In theory, you could write your entire program on one line, or one way too many lines, with each word on a new line.

Stick in the \n character and you'll be fine.

don't open that text file in notepad afterwards, it doesn't recognise \n. use something like wordpad to check if it worked.

Notepad will see it just fine.

It doesn't recognize a literal LF-CR character, but as far as it's concerned, the "\n" in the source code is a backslash followed by an n, ie two separate characters.

In property files there is a control character to span new lines think it is ...

\

at the end of the line or maybe

/

(been a while and I tend not to do it as it confuses the hell out of people).

could put the text into a property file and use that? otherwise the \n will do.

p.println ("text text text text\n" +
"text text text text\n" +
"text text text text\n" +
"text text text text\n" +
"text text text text");

that should do it. However,as Auburn suggested, better practice would be to buffer (Quick example from some pre-existing code= )

<code>

private BufferedWriter outStream;
private String fileName="file.txt";

/**
* Writes to file
* @param String this is the string that is written to file
*/

public boolean writeLogEvent( String s ){
try{
BufferedWriter outStream = new BufferedWriter( new FileWriter( fileName, true ) );
String writeFormattedString;

writeFormattedString= s;

outStream.write(writeFormattedString + "\n");
// testing:
// System.out.println(writeFormattedString);

//close stream:
outStream.flush();
outStream.close();

return true;
}
catch(IOException e)
{
}

return true;
}

</code>
