java try return finally

由一个笔试题想到的
try有return,catch也有return,且有finally块
并且finally中对resutl进行的赋值并不影响之前的已经return 的result值
最后返回的result引用还是之前的result引用
finally其实也可以有return，一般eclipse会提示finally block does not complete normally,但不会报错
并且会忽略之前的返回和抛出的异常

packagereturnfinally;

publicclassTestReturnAfterFinally{

publicstaticvoidmain(String[]args){
try{
Stringresult=testException();
System.out.println();
System.out.println(result);
}catch(Exceptione){
//System.out.println(result);
System.out.println(e.toString());
}
}

publicstaticStringtestException()throwsException{
Stringresult="";
try{
//if(true)thrownewMyException("异常！");
//inti=0;
inti=0;
intb=10/i;
//函数不会正常的返回,在返回前已经抛出异常了，抛出异常即函数返回了
/**//*
*相当于catch(Exceptione){
*throwe;
*}
*/
/**//*
result="intry";
returnresult;
*/
thrownewException("h");
}catch(Exceptione){
System.out.println(e);
Exceptionee=e;
//throwee;
result="incatch";
returnresult;
}
finally{
result="infinally！";
System.out.println(result);
//returnresult;
//thrownewException("excretatedinfinally");
}

//returnresult;
}

}
