Q&A
この Java プログラムは HTML を作っているだけです.
3 回動くかどうかは HTML 側の問題かと思いますので, まずこのプログラムで作った HTML を直接手で直してご希望通り動くようにし, その結果出来た HTML ファイルをこのプログラムで作るように修正されるのが良いかと思います.
ですので, HTML(JavaScript?) の質問を作られては如何でしょうか.
java初心者です。
Aという文字を3回連続で順番に飛ばしたいです。ですが今のままでは一回しか動きません。
いかにコードを貼ります。
java
1class A{ 2 public static void main(String args[]) { 3 double x, y, x_speed, y_speed; 4 double g; 5 int r,c; 6 7 g = -10; 8 r = 10000; 9 c = 0; 10 11 x = 0; 12 y = 100000; 13 x_speed = 800; 14 y_speed = 0; 15 16 System.out.print("<html><head><style type=\"text/css\">#flyingObject { position:absolute; left:0px; top:30px; width:3em; }#catchObject { position:absolute; left:0px; top:30px; width:3em; }</style><script type=\"text/javascript\">var flyobj = null;var catobj = null;var count = 0;var distmax = 140000;var hmax = 100000;var theoval = 113137.08498984762;var movedata = new Array("); 17 18 while( y >= 0 ) { 19 y_speed = y_speed + g/r; 20 x = x + x_speed/r; 21 y = y + y_speed/r; 22 23 c++; 24 if( c == r ) { 25 System.out.print("" + x + "," + (100000-y) + ",\n"); 26 c = 0; 27 } 28 } 29 System.out.print("" + x + "," + (100000-y) + ""); 30 /* System.out.print("estimated distance = " + x + "\n"); */ 31 32 System.out.print("); function doAnimLoop() { flyobj.style.left = parseFloat(movedata[count])*800/distmax + 'px'; flyobj.style.top = parseFloat(movedata[count+1])*400/hmax + 'px'; count+=2; if( count < movedata.length ) { setTimeout(doAnimLoop,20); } else { if( (parseFloat(movedata[count-2]) - theoval > 3) || (parseFloat(movedata[count-2]) - theoval < -3) ) { flyobj.style.background = 'red'; } else { flyobj.style.background = 'transparent'; } }}function doAnimStart() { flyobj = document.getElementById('flyingObject'); flyobj.style.left='0px'; flyobj.style.top='0px'; catobj = document.getElementById('catchObject'); catobj.style.left=theoval*800/distmax +'px'; catobj.style.top=400+'px'; doAnimLoop();}window.onload = doAnimStart;</script></head><body><div id=\"flyingObject\">A</div><div id=\"catchObject\"> </div></body></html>"); 33 return; 34 } 35} 36
物理の水平投射を使って文字を飛ばしています。
自分はこの動きを3回動作させたいです。
自分はこのhtmlを3つ書いてみたのですが、「2回目以降のところにプログラムは移りません」
とエラーが出てしまいます。
どこをどのようにすることで実現するか、知りたいです。よろしくお願いいたします。

付け焼刃ですが, 動いたようなので回答してみます.
と言っても java で無く java を動かして出来る html のほうです.
行ったのは, loopcount 変数の追加と, それを使った doAnimLoop の繰り返しの追加です.
java の方は, こういうコードを出力するように System.out.print() の中の文字列を変更してください.
JavaScript
