textboxコードの下のクラスに文字列を表示したいのですが、表示vpsfameできません。このクラスの文字列new8がコードで表示され、シリアルクラスが gps continue からの文字列を提供してくれることを教えてください。また、System.out.println を介して実行時に表示されますが、textboxofvpsfameクラスを介しては表示されません。

タイムアウトを取り、すべてのコードをリファクタリングすることを真剣にお勧めします。class でそれを無視して、new8メソッドで次のdecodeコードを置き換えます。

new vpsfame().ac.setText(t[1].substring(1,2));
System.out.println("Lattitude:                                  "+t[3]);


System.out.println("Direction of Lattitude:                     "+t[4]);
new vpsfame().ab.setText(t[3].concat(t[4]));
System.out.println("Longitude:                                  "+t[5]);
System.out.println("Direction of Longitude:                     "+t[6]);
new vpsfame().bc.setText(t[5].concat(t[6]));
System.out.println("Speed over Ground:                          "+t[7]);
new vpsfame().cd.setText(t[7]);

これとともに:

//use one object, dont just create new frames
vpsfame myFrame = new vpsfame();

myFrame.ac.setText(t[1].substring(1,2));
System.out.println("Lattitude:                                  "+t[3]);
System.out.println("Direction of Lattitude:                     "+t[4]);

myFrame.ab.setText(t[3].concat(t[4]));
System.out.println("Longitude:                                  "+t[5]);
System.out.println("Direction of Longitude:                     "+t[6]);

myFrame.bc.setText(t[5].concat(t[6]));
System.out.println("Speed over Ground:                          "+t[7]);
myFrame.cd.setText(t[7]);

//Also set the frame to visible, so it can be displayed once you've done all this work.
myFrame.setVisible(true);

問題はそれです:

  1. まず、1 つしか持たないはずの複数の vpsframe オブジェクトを作成しています。それぞれが 4 つの空のフィールドを持つ 5 つのフレームを作成しても意味がありません。5 つの異なるオブジェクトを使用するのではなく、1 つのオブジェクトを作成し、そのすべてのフィールドを初期化します。
  2. 作成しているオブジェクトを追跡していません。ガベージコレクターはただ取り除くだけなので、1 つのオブジェクトを作成し、それを変数に割り当てて使用します。
  3. vpsfame オブジェクトを表示するように設定します。そうしないと表示されません。

コードもリファクタリングが必要です。キャメルケースの命名規則を使用し、クラスは常に大文字で始める必要があります。
