Before I write any code, I'm going to figure out all of the dimensions and

コードを書く前に長方形の大きさと仕様を

specifications of my rectangles. Box will match the specifications given. So,

すべて確認していきます boxの仕様は先ほど設定しました

it'll be at 60, 90 and have a width of 20 and a height of 30. The question asks

すると60と90の位置に配置して幅が20で高さが30となります

for the dimensions of both boxes to be the same. So this one will also be 20

大きさはどちらのboxも同じなので幅は20

wide and 30 tall. I need to figure out where this upper left corner is. It

高さは30です box2の左上の位置も把握する必要があります

looks like it's 20 to the right from 60, so that should be at 80. And it's also

幅は60の位置から右に20行ったところつまり80です　同様に90の位置から

30 down from 90, so that should 120. Now, I have all of the specifications, and

下に30行ったところは120ですこれで情報がそろいました

I need to put them into the constructor calls. So, in the BlueJ project, I'll

あとはこれらの値をコンストラクタの呼び出しに入れます

edit the code for rectangle demo. Open editor. And then the main method, I'm

BlueJプロジェクトでRectangleのデモ用のコードを編集します　まずエディタを開き

going to create two rectangles: Box and Box Two. And then once I've created

mainメソッドに2つの長方形boxとbox2を作成しますここまでできたら

them, I'm going to draw them. We'll make box a new rectangle. Now, this

長方形を描いていきます boxをnew Rectangleにします

constructor needs to take an x, a y, a width and a height. X we know is 60, y

そしてこのコンストラクタに x、y、幅、高さを入れていきます

is 90, the width is 20 and the height is 30. Now for box two, x is 80, y is

xは60、yは90、幅は20、高さは30です

120, the width is 20 and the height is 30. So if I stretch this out, it should

同様にbox2もxは80、yは120、幅は20、高さは30です　画面を拡大しますね

look like this. Let's compile, and now I'll run my method. And it drew my

コンパイルしてみましょう　メソッドを実行します

rectangles, just as I asked for.
