私は自分のswingインターフェースに次のボタンを持っています

    private void solveButtonMouseClicked(java.awt.event.MouseEvent evt) {                                         


    step1(); 


}

step1() を呼び出します。

   private void step1(){

//step 1 solving the white cross around the yellow middle
        while( (!(F2.getBackground().equals(white))) & (!(F4.getBackground().equals(white))) & (!(F6.getBackground().equals(white))) & (!(F8.getBackground().equals(white)))){


         textArea.append("cnt");

        //top three pieces solved
        if(F2.getBackground().equals(white) && F4.getBackground().equals(white) && F6.getBackground().equals(white)){
            //solve F8 
            while(!(F8.getBackground().equals(white))){

問題は、step1() の一番外側の while ループのようです。すべての条件が満たされるまで実行し続けるはずですが、1回の反復後に停止するだけで、理由がわかりません。外側の while ループを削除すると、 step1() は、ボタンを複数回押したときに各ステップを通過する必要があるのとまったく同じように進行します。ヘルプ！

すべての比較が真になるまでループを続けたいと述べています。

現在のコーディング方法では、いずれかの条件が真になるとループから抜け出します。

それよりも

while ( !boolean1 && !boolean2 && !boolean3) {

試す

while ( ! (boolean1 && boolean2 && boolean3) ) {

おそらく、up/down/left/right/left/leftinv などのメソッドの 1 つが、色をテストしている背景を変更しているため、while 条件が false と評価され、1 回以上の反復が妨げられています。

私の推測では、JVM はそのテキストの壁に達し、私たちと同じように、それをどう処理するか、また何をしたいのかわかりません。

それ、または&の代わりに使用しています&&。

しかし、正直なところ、巨大な分岐 else-if はしごをループして適用している場合は、かなり深刻な間違いを犯しています。たとえ機能するようになったとしても、この種のコードはプロセッサにとって地獄であり、維持するのが面倒なことは言うまでもありません。私の推奨事項: リファクタリング。

私の最初の推測は、ループで論理比較「&&」ではなく、ビットごとの「&」を使用しているように見えるということです。
