GUI を完成させようとしていたとき、いたるところでエラーが発生していることに気付きましたが、それ以前はすべて問題なく動作していました。別のパネルを呼び出そうとすると、「シンボルが見つかりません」というエラーが表示されます。
this.setContentPane(servicios);
とエラー"Class, interface or enum expected" on object methods and some "}":
text.setText(text.getText()+"\nInternet 20 mbps = $1199");
私は間違っているように見えるものを見つけることができません。
これはコンソールからのエラーです: Exception in thread "main" java.lang.VerifyError: Constructor must call super() or this() before return in method sistema.Principal.()V at offset 0 at sistema.Sistema.main (Sistema.java:18) Java 結果: 1
コードは次のとおりです。
