+##问题
+
+有一个 try/catch 代码块，其中包含一个打印语句。finally代码块总会被执行么？
+
+示例：
+
+``` java
+try {  
+    something();  
+    return success;  
+}  
+catch (Exception e) {   
+    return failure;  
+}  
+finally {  
+    System.out.println("i don't know if this will get printed out.");
+}
+```
+
+##回答
+
+1. ```finally``` 将会被调用。
+
+   只有以下情况 ```finally``` 不会被调用：
+
+ - 当你使用 ```System.exit()``` 后
+ - 其他线程干扰了现在运行的线程（通过 ```interrupt``` 方法）
+ - 如果 JVM 已经“撞毁”了

+2. //示例代码
+
+``` java
+class Test
+{
+    public static void main(String args[]) 
+    { 
+    	System.out.println(Test.test()); 
+    }
+
+    public static int test()
+    {
+    	try {  
+            	return 0;  
+    	}  
+    	finally {  
+    	    System.out.println("finally trumps return.");
+    	}
+    }
+}
+```
+   输出：
+
+``` java
+finally trumps return. 
+0
+```
