Is there a way to split a string by line breaks ?

// Placing text in jtextarea called area
                                    area.read(new FileReader(fc.getSelectedFile()),null);
    area.setEditable(false);
    JOptionPane.showMessageDialog(null, "Open File Successful");
    String data = area.getText();
    lines = new String[10];
    lines = data.split ('\n');

Fixed it it had to be "\\n" instead of '\n'

You have just allocated an array of ten Strings, then immediately lost
your reference to it. Try:

String[] lines = s.split("\n");

Only a single backslash should be needed, i.e. "\n".

import java.io.PrintWriter;

public class Main {
public static void main(String[] args) {
PrintWriter out = new PrintWriter(System.out, true);
String s = "hello\nworld";
String[] lines = s.split("\n");

int lineNo = 0;
for(String line: lines) {
out.println(++lineNo + ": " + line);
}
}
}

C:\files\usenet\java>java -cp . Main
1: hello
2: world
