java - 将对象[][] 转换为字符串？ Java Swing

Question

我需要转换一个如下所示的 Object[][]:

Object[][] numbers =
  {"1", "12-22", "12-22"},
  {"2", "12-22", "11-14"},
  {"3", "12-22", "11-14"};

我试过:

m1.textArea.setText((b1.returnNumbers).toString());

Answer 1

您可以使用 deepToString方法:

m1.textArea.setText(Arrays.deepToString(b1.returnNumbers));
