not appending string to the file

[mgl70]

Hi ,

I am getting trouble by using FileWriter.
I created a file by using FileWriter class.
I called the file from some other class.
In the second class, I am able to write a string to that file.
I application is still active. But I am not able to append another string to that file eventhough I gave "true".
Whats my problem.

Class1{

void method1(){

FileWriter fr = new FileWriter(filename,true);

}

}

Class2{

void method2()
{
String mystring;
fr.write(mystring);
fr.close();



}
here I am able to write the string to that file. but next time it is suposed to merge the second string to that file. It is not merging.

I appreatiate all your help,

Try something a bit more like :

public class Test {
	class Test2 {

			FileWriter fw = null;

			public Test2() {
				try {
					fw = new FileWriter("test.txt", true);
				} catch (IOException ioe) {
					ioe.printStackTrace();
				}
			}

			public void write(String s) throws IOException {
				fw.write(s);
				fw.flush();
			}

			public void close() throws IOException {
				fw.close();
				fw = null;
			}

	}

	public void doIt() throws IOException {
		Test2 t2 = new Test2();
		t2.write("hello");
		t2.write("\n");
		t2.write("there");
		t2.write("\n");
		t2.close();
	}


 	public static void main(String args[]) throws Exception {

		new Test().doIt();
	}
}
