Hal yang perlu dilakukan selanjutnya di aplikasi yaitu mengatur harga kopi

The next thing to do in our app is to change the price of the coffee

dalam hal seseorang memesan lapisan atas, seperti krim kocok atau cokelat.

in case someone orders a topping, like whipped cream or chocolate.

Ide yang bagus.

That's a good idea.

Jika mereka memesan krim kocok, maka kita hanya cukup mematok harga $1.

If they order whipped cream, then we'll just charge them $1.

Jika mereka memesan cokelat, maka kita hanya cukup mematok harga $2.

If they order chocolate, then we'll charge them $2.

Benar. Mari kita ketahui bagaimana melakukan ini di dalam aplikasi.

>> Right. Let's figure out how to do this in the app.

Ini beberapa contoh dalam aplikasi Google yang lain,

Here are a couple of examples in other Google apps,

di mana perilaku bisa berubah berdasarkan keadaan tertentu.

where the behavior can change based on certain conditions.

Dalam aplikasi Inbox dari Gmail, ini adalah tangkapan layar daftar surel.

In the Inbox app from Gmail, here's a screen shot of the list of emails.

Untuk satu surel, jika ada peringatan terlampir padanya,

For a single email, if there is a reminder attached to it,

maka aplikasi tahu untuk menampilkan ikon, label dan teks peringatan ini.

then the app knows to show this icon, this label and the reminder text.

Jika surel mempunyai lampiran gambar,

If an email has image attachments,

maka aplikasi akan menampilkan gambar tersebut pada baris ini.

then the app knows to show those images in line here.

Jika surel menyebutkan sebuah perjalanan,

If an email mentions a trip,

maka kartu perjalanan muncul dengan informasi penerbangan.

then a travel card shows up with the flight information.

Dalam aplikasi Google Now Launcher, kita mempunyai contoh lebih tentang bagaimana

In the Google Now Launcher app, we have more examples of how the app

perilaku aplikasi berubah berdasarkan keadaan tertentu.

behavior changes based on certain conditions.

Contohnya, jika harga stok bertambah,

For example, if the stock price is increasing, then the delta or

maka delta atau pertambahan harga akan ditampilkan di sini dengan huruf berwarna hijau.

the increase in the price will be shown here in green font color.

Jika harga stok berkurang,

If the stock price is decreasing,

maka selisihnya akan ditampilkan di sini dengan huruf berwarna merah.

then the difference will be shown here in a red font color.

Untuk kartu cuaca ini, jika suhunya baik dan cuacanya cerah,

For this weather card, if the temperature is good and

maka kami menampilkan ikon matahari.

the weather is sunny, then we show a sun icon.

Jika cuacanya berangin atau mendung, maka kami menampilkan ikon berbeda.

If the weather is windy or cloudy, then we show different icons.

Kami akan memodifikasi aplikasinya

We'll be modifying our app shortly so

agar harga diatur berdasarkan lapisan atas yang dipesan

that the price changes based on the toppings ordered but

tapi pertama-tama, saya ingin kau mengenal arus kontrol.

first, I want you to become familiar with control flow.

Secara normal, kode dalam metode kami dijalankan dari atas ke bawah,

Normally, the code in our methods gets executed from top to bottom,

baris ke baris tetapi dengan pernyataan arus kontrol,

line after line but with control flow statements,

kau bisa mengganti bahwa instruksinya dijalankan.

you can change that instructions are executed in.

Contohnya, kau bisa melewati instruksi tertentu jika persyaratan tertentu terpenuhi.

For example, you can skip certain instructions if certain conditions are met.

Kita akan melakukan ini dengan mempelajari logika <i>if/else.</i>

We're going to do this by learning about if/else logic.

Kau belum tahu kode pernyataan <i>if/else</i> sebelumnya

You haven't seen code for if/else statements before but

tapi saya akan membiarkanmu untuk memahaminya.

I'm going to throw you in the deep end and see how you do.

Dalam beberapa tantangan berikutnya, kau akan membaca potongan kodemu sendiri

In the next couple of challenges, you're going to read some code snippets on your

dan ini adalah tautan dalam catatan instruktur.

own, and these are linked in the instructor notes.

Lalu kau akan mencoba untuk menebak kode ini untuk apa dan

Then you're going to try to guess what this code does and

cobalah tentukan pengeluarannya.

try to determine the output.

Kau punya beberapa pilihan,

You'll have several options to choose from so

kau bisa memilih yang terbaik yang cocok dengan kode ini.

you can choose the best one that matches this code.

Saat saya berkata pengeluaran,

When I say output,

saya merujuk pada pernyataan <i>log</i> yang tercetak ke <i>log cat</i>.

I'm referring to the log statements that get printed to the log cat.

Ingatlah bahwa kau bisa mengakses <i>log cat</i> dari tablet Android tepat di sini,

Remember that you can access log cat from this Android tab right here,

dan ini menampilkan semua pesan dari sistem dan dari aplikasi kami.

and it shows all the messages from the system, and from our apps.

Potongan kode yang kami sediakan untukmu

The code snippets that we're providing to you are going to be writing messages

akan menulis pesan ke <i>log</i> di sini.

to the log here.

Mari kita membuat contoh pertanyaan bersama-sama.

Let's do a sample question together.

Kau bisa menemukan tautan ini dalam catatan instruktur.

You can find this link in the instructor notes.

Anggaplah bahwa ini potongan kode dari berkas <i>WeatherActivity.java</i>

Assume that this is a code snippet from a WeatherActivity.java file

di dalam aplikasi cuaca.

within a weather app.

Kode di baris pertama menciptakan variabel <i>boolean</i> yang disebut <i>isRaining</i>

The first line of code creates a boolean variable called isRaining and

dan nilai inisialnya benar.

the initial value is true.

Lalu kita memiliki pernyataan <i>if/else</i> ini.

Then we have this if/else statement.

Jika <i>is raining</i> benar, maka kita menulisnya di <i>log</i>.

If is raining is true, then we write this to the logs.

Dia berkata, ini hujan, lebih baik membawa payung.

It says, It's raining, better bring an umbrella.

Jika <i>is raining</i> salah, maka kita mengarah ke kas <i>else</i> dan kita tulis,

If is raining is false, then we go into this else case and we write,

pesan ini, sepertinya tidak akan hujan.

this message, It's unlikely to rain.

Karena <i>is raining</i> benar, maka kita mengarah ke kasus ini

Since is raining is true, then we fall into this case and

dan kita tulis, ini hujan, lebih baik membawa payung.

we write, It's raining, better bring an umbrella.

Karena kita berada di kasus ini, kita bisa melewati blok <i>else</i>, baris kode ini

Because we fall into this case, we can skip the else block, this line of code

berada di luar pernyataan <i>if/else</i> jadi ini selalu dijalankan.

lives outside the if else statement so it always gets executed.

Dia berkata, Terima kasih telah menggunakan <i>WhetherWeather App</i>.

It says, Thank you for using the Whetherweather App.

Mari kita cari pilihan dalam kuis yang menampilkan,

Let's look for an option in the quiz that shows, It's raining,

ini hujan, lebih baik membawa payung, langsung diikuti dengan,

better bring an umbrella., immediately followed by, Thank you for

Terima kasih telah menggunakan <i>WhetherWeather App</i>.

using the WhetherWeather App.

Itu tepatnya pilihan B.

That's exactly option B.

Ini masalah berbeda untuk kau coba sekarang.

Now here's a different problem for you to try.

Periksalah catatan untuk potongan kode dan tentukan pilihanmu.

Check the notes for the code snippet and then make your selection.
