Javaで長方形オブジェクトをJPEGで塗りつぶす

Question

私はクラスプロジェクトで、PC上でFlappy Birdクローンを再作成しています。私はこれまでのところこのコードを持っていますが、赤い矩形の「鳥」をペンギンのJPEGに置き換えたいと思います。これについてどうやって行くかについてのアイデア？私はオンラインで研究してきましたが、それを正しく得ることはできません。私はJavaで2Dグラフィックの仕事をしたことがありません。ありがとうございました！

あなたはGraphicsオブジェクトのdrawImage()方法を使用することができます

g.drawImage(yourImage,xPos,yPos,null);
