1. 在try中return后,finally是否会执行?
是
2. 在try中throw exception后,finally是否会执行?
是
3. 在try中System.exit(0)后,finally是否会执行?
否
例子:
public class Test2 {
public static void main(String[] args) throws Exception {
returnValue();
tryException();
exit();
}
public static int returnValue() {
try{
return 0;
} finally {
System.out.println("finally in returnValue");
}
}
public static void tryException() throws Exception {
try{
throw new Exception("My exception");
} finally {
System.out.println("finally in tryException");
}
}
public static void exit() {
try{
System.exit(0);
} finally {
System.out.println("finally in exit");
}
}
}
以下是屏幕输出:
finally in returnValue
finally in tryException
Exception in thread “main” java.lang.Exception: My exception
