package com.ray.ch10;public class Test {private void test() throws Exception {throw new Exception();}public static void main(String[] args) {try {new Test().test();} catch (Exception e) {e.printStackTrace();} finally {System.out.println(finally);}}}

Output:

 

Java. lang. Exception

package com.ray.ch10;public class Test {public static void main(String[] args) {int i = 0;while (true) {try {if (i++ == 0) {throw new Exception();}} catch (Exception e) {e.printStackTrace();} finally {System.out.println(finally);if (i == 2) {System.out.println(break);break;}}}}}

Output:
