Issue while writing to file

[karan chandok]

FileOutputStream f1 = new FileOutputStream("D:/File.txt");
PrintStream ps = new PrintStream(f1);
Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
Connection c = DriverManager.getConnection(url + ";database=" + dbName, userName, password);
Statement stmt = c.createStatement();
String[] files = new String[100];
File search = new File("D:/Content");
files = search.list();
System.out.println("files" + files.length);
ResultSet rs = stmt.executeQuery("select distinct content_id from tbl_live_songs ");

while (rs.next()) {
child_node = rs.getString("content_id");
String content_id = child_node + ".wav";
String str1 = rs.toString();


for (int i = 0; i < files.length; i++) {

//System.out.println("files"+files.toString());

System.out.println(files[i]);


String temp = "";
int n = 0;



StringBuffer st = new StringBuffer(temp);
String str = st.toString();

//System.out.println(":::::" + str);
if ((content_id.equals(files[i]))) {
System.out.println("wrong");
} else {



ps.println(child_node);

}
}

}
