Java PrintWriter File Overwrite -


i want write file using utf-16 use printwriter(file,"utf-16"), deletes in file, use filewriter(file,true), wouldn't in utf-16, , there apparently isn't constructor printwriter printwriter(writer,charset,boolean append);

what should do?

the javadoc filewriter says:

the constructors of class assume default character encoding , default byte-buffer size acceptable. specify these values yourself, construct outputstreamwriter on fileoutputstream.

so can do:

 writer writer = new printwriter(      new outputstreamwriter(            new fileoutputstream(filename, true),            standardcharsets.utf16));

you might want include bufferedoutputstream in there maximum efficiency.

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m
