Question

public class Math {
  public static int divide(int a, int b) {
    try {
      int result = a / b;
      return result;
    } catch (ArithmeticException ae) {
      System.out.println("Error! Divided by zero!");
    } finally {
      return 0;
    }
  }

  public static void main(String[] args) {
    int result = Math.divide(10, 2);
    System.out.println("result = " + result);
  }
}

答案将为零，如@Stephen建议的here所述。

但是我认为您正在尝试解决它。就像有例外一样，则返回0 ；我建议两种方法

第一个带有Set results = html.getElementsByClassName("lemon--div__373c0__1mboc largerScrollablePhotos__373c0__3FEIJ arrange__373c0__UHqhV border-color--default__373c0__2oFDT") Debug.Print results.Length Dim output(), r As Long ReDim output(1 To results.Length, 1 To 3) r = 1 For i = 0 To results.Length - 1 'On Error Resume Next html2.body.innerHTML = results.Item(i).innerHTML output(r, 1) = html2.getElementsByClassName("lemon--a__373c0__IEZFH link__373c0__29943 link-color--blue-dark__373c0__1mhJo link-size--inherit__373c0__2JXk5")(0).innerText output(r, 2) = html2.getElementsByClassName("lemon--p__373c0__3Qnnj text__373c0__2pB8f text-color--normal__373c0__K_MKN text-align--right__373c0__3ARv7")(0).innerText output(r, 3) = html2.getElementsByClassName("lemon--p__373c0__3Qnnj text__373c0__2pB8f text-color--normal__373c0__K_MKN text-align--right__373c0__3ARv7")(1).innerText 'On Error GoTo 0 r = r + 1 Next ws.Cells(GetLastRow(ws, 1) + 1, 1).Resize(UBound(output, 1), UBound(output, 2)) = output块的方法（也许它最适合您）；

finally

第二个没有public static int divide(int a, int b) { int result = 0; try{ result = a / b; return result; } catch (ArithmeticException ae) { System.out.println("Error! Divided by zero!"); }finally { return result; } }块的

finally

我认为这些可以帮助您
