有這樣一段代碼?：

public class EmbededFinally {

??? ?public static void main(String args[]){

??????? ??int result;

??????? ??try {

??????????? ???System.out.println("in Level 1");

?

?????????? ?? ?try {

??????????????? ????System.out.println("in Level 2");

? // result=100/0;? //Level 2

?????????????? ?????try {

?????????????????? ???? ?System.out.println("in Level 3");

????????????????????? ???? ?result=100/0;? //Level 3

??????????????? ????}

??????????????? ????catch (Exception e) {

??????????????????? ?????System.out.println("Level 3:" + e.getClass().toString());

??????????????? ????}

??????????????? ??????????????? ????finally {

??????????????????? ?????System.out.println("In Level 3 finally");

??????????????? ????}

??????????????? ?????????????? ????// result=100/0;? //Level 2

??????????? ????}

??????????? ???catch (Exception e) {

?????????????? ??? ?System.out.println("Level 2:" + e.getClass().toString());

?????????? ?? ?}

?? ?finally {

??????????????? ????System.out.println("In Level 2 finally");

?????????? ??? }

???????????? ???// result = 100 / 0;? //level 1

??????? ??}

??????? ??catch (Exception e) {

??????????? ???System.out.println("Level 1:" + e.getClass().toString());

??????? ??}

??????? ??finally {

?????????? ?? ?System.out.println("In Level 1 finally");

??????? ??}

??? ?}

當我去掉level2中level3前面的注釋時，level3的catch不再執行；

當我去掉level2中level3后面的注釋時，level3的catch執行；

所以得到，當try中發現異常并拋出異常之后則不向下執行，直接轉到catch接收異常，最后執行同層次finally。
