boolean test() throws Exception {
boolean ret = true;
try {
int b = 12;
int c;
for (int i = 1; i >= -2; i--) {
c = b / i;
System.out.println("i=" + i);
}
return true;
} catch (Exception e) {
System.out.println("testEx2, catch exception");
ret = false;
throw e;
} finally {
System.out.println("testEx2, finally; return value=" + ret);
return ret;
}
}
这是一种很不好的写法。
开始认为会输出
i=12
testEx2, catch exception
testEx2, finally; return value=false
但事实是
i =12
testEx2, finally; return value=false 原因是finally里写return return会冲掉上边的return 并且干掉catch抛出的异常
