java - 'else' without 'if' despite use of braces -


i've been getting 'else' without 'if' error following code , i'm not sure why. i've used braces , i'm confused.

        if(mean >= 90 && mean <= 100){             grade = 'o';}          else{              if(mean >= 80 && mean < 90)             grade = 'e';}          else{              if(mean >= 70 && mean < 80)             grade = 'a';}          else{              if(mean >= 55 && mean < 70)             grade = 'p';}          else{              if(mean >= 40 && mean < 55)             grade = 'd';}          else{              if(mean < 40)             grade = 't';}

i think not using right structure if-else if statement in java. should : 

if (testscore >= 90) {     grade = 'a'; } else if (testscore >= 80) {     grade = 'b'; } else if (testscore >= 70) {     grade = 'c'; } else if (testscore >= 60) {     grade = 'd'; } else {     grade = 'f'; }

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

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() .
