今から、考えてみまっする

/*TreeMapクラス,Collection<E>インターフェースの登録されているパッケージ*/
import java.util.*;
/*FileReader,BufferedReaderクラスの登録されているパッケージ*/

まず、Mainからね。


import java.text.*;
import java.util.*;
class Main{
public static void main(String[] args){
CFrame cf1= new CFrame();
cf1.setLocation(0,0);
CFrame cf2= new CFrame();

CFrame cf3= new CFrame();
cf3.setLocation(200,200);

while(true){
if(cf1.button1){

if(cf2.button1){
cf2.repaint();}
if(cf3.button1){
cf3.repaint();}
try{
Thread.sleep(500);

次、CFrameね。

public void repaint(){

}


他に良いの出来ればうｐよろしく。

ナイスｂ

動き遅せぇけど、一応載せとくね。
イジったのはMainだけだったと思うんで。


/** ボールの等速運動
* ボールの個数は，実行指令の引数で指定することができる。
* （引数を書かなければ，ボールは1個だけとなる。）
*/
class Main{
public static void main(String[] args){
int n= 1;
if( args.length > 0 ) n= Integer.parseInt(args[0]);
Ball[] b = new Ball[n];
BFrame bf= new BFrame(300,200);
for(int i= 0; i!=n; i++){
b[i] = new Ball(bf);
}
while(true){
for(int i=0;i<n-1;i++){
for(int j=i+1;j<n;j++){
if(Math.sqrt((b[i].x-b[j].x)*(b[i].x-b[j].x)+(b[i].y-b[j].y)*(b[i].y-b[j].y))<b[i].r){

}
}
}
}
}
public static void Clash(Ball a,Ball b){
double tmp;
tmp=a.dx;
a.dx=b.dx;
b.dx=tmp;

a.dy=b.dy;

}
}

相変わらず動き遅せぇけど、上の改良版です。
ボールの半径がバラバラになって、質量なんかも考えてあります。

じゃあ、Mainから。

次、Ballね。

}

return Math.random()*(u-l) +l;
}
public void run(){
while( active ){
final double eps= 1.0; /* 減衰率 */
x+= dx;
if( x < r ){ x= 2*r-x; dx*= -eps; dy*= eps;}
if( x > width-r ){ x= 2*(width-r)-x; dx*= -eps; dy*= eps; }
y+= dy;
if( y < r ){ y= 2*r-y; dy*= -eps; dx*= eps; }
if( y > height-r ){ y= 2*(height-r)-y; dy*= -eps; dx*= eps; }
if( Math.sqrt(dx*dx+dy*dy) < 0.5 ){ kill(); frame.remove(this); }
try{ Thread.sleep(40); }catch(InterruptedException e){}
}
}
public void kill(){ active= false; }
public void paint(Graphics g){
g.setColor(c);
g.fillOval((int)x-(int)r, (int)y-(int)r, 2*(int)r, 2*(int)r);
}
public double gravity(double r){
double grv = r*r*3.14;
return grv;
}
}



重いんで、実行するときはボールを３つくらいにするといいよ。
