java - Use window builder jframe in a different class -


i trying use gui built window builder in eclipse using jframe. have tried call method ftwo(); in main method , imported class not recognize method package com.cameron.main;

import java.awt.borderlayout; import java.awt.eventqueue;  import javax.swing.jframe; import javax.swing.jpanel; import javax.swing.border.emptyborder;  public class ftwo extends jframe {        private jpanel contentpane;      /**      * launch application.      */     public static void main(string[] args) {         eventqueue.invokelater(new runnable() {             public void run() {                 try {                     ftwo frame = new ftwo();                     frame.setvisible(true);                 } catch (exception e) {                     e.printstacktrace();                 }             }         });     }      /**      * create frame.      */     public ftwo() {         setdefaultcloseoperation(jframe.exit_on_close);         setbounds(100, 100, 450, 300);         contentpane = new jpanel();         contentpane.setborder(new emptyborder(5, 5, 5, 5));         contentpane.setlayout(new borderlayout(0, 0));         setcontentpane(contentpane);     }  }

assuming myapp in same java package, instantiate new ftwo instance , set visible. example:

import java.awt.*;  public class myapp {     public static void main(string[] args) {         ftwo ftwo = new ftwo();         eventqueue.invokelater(() -> ftwo.setvisible(true));     } }

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

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...

sql server - Why does Linq-to-SQL add unnecessary COUNT()? -

here tables: create table customer ( cid int primary key, name varchar(32) ) create table ord ( oid int primary key, cid int foreign key references customer, address varchar(20) ) here's linq-to-sql statement: var aaa = c in db.customer select new { c, o = c.ord.tolist() }; and here's inexplicable query generated linq-to-sql: select [t0].[cid] [cid], [t0].[name] [name], [t1].[oid] [oid], [t1].[cid] [cid2], [t1].[address] [address], (select count(*) [dbo].[ord] [t2] [t2].[cid] = [t0].[cid]) [value] [dbo].[customer] [t0] left outer join [dbo].[ord] [t1] on [t1].[cid] = [t0].[cid] order [t0].[cid], [t1].[oid] i want understand how rid of count(*) part. it's entirely uncalled for! linq needs count(*) in order determine number of entries returned o = c.ord.tolist() .
