write strings into text file

[bbvic]

this codes works with 1.5 , but it does not work with 1.4..
The error sign is that the method format(String, Object[]) is undefined for the type String.
can you help me how it works with 1.5?

import java.io.*;
import java.util.*;


public class Main {
public static void main(String[] args) {

String [] test =null;
String str1="Today";
String str2="is";
String str3="monday";
String str4="good";

String format = "%1$-9s%2$-3s";
format +="%3$-30s%4$-30s\n";
test = new String[] {str1, str2, str3,str4};
File f = new File("D:\\temp\\test.txt");

try
{
if ( f.exists() )
{

PrintStream ps = new PrintStream(new FileOutputStream("D:\\temp\\test.txt"));
ps.println(String.format(format,(Object[])test));
ps.flush();
ps.close();
}
else
{
PrintStream ps = new PrintStream(new FileOutputStream("D:\\temp\\test.txt"));
ps.println(String.format(format,(Object[])test));
ps.flush();
ps.close();
}
}
catch (Exception e)
{
System.out.println(e);
}
}
}

You like to know how it is implemented?

btw.: Use code-tags for indentation of code the next time, please.

Hi,
Take a look at the apache commons

http://jakarta.apache.org/commons/

I use the "org.apache.commons.io.FileUtils"
It's very easy.
-----------
String2File
-----------
FileUtils.writeStringToFile("filename.txt","my content","UTF-8");

-----------
File2String
-----------
String content = FileUtils.readFileToString("filename.txt","UTF-8"));
