JAVA 加强版for编译出错

[fangcaixia498602700]

代码如下：
private void checkUserGuess(String userGuess){
numOfGuesses++;

String result = "miss";
for(DotCom dotComToTest : dotComsList){
result = dotComToTest.checkYourself(userGuess);
if( result == "hit" ){
//System.out.println("hit");
break;
}
if( result == "kill" ){
//System.out.println("kill");
remove(dotComToTest);
break;
}
}

}

编译出错：

JAVA自学者一颗。希望大家指点下。之前也遇到类似错误，后来是通过改用原始的for解决的。现在又碰到了，看来不能去躲避啊。我猜测会不会是用的JAVA版本的问题呢。我的版本是

F:\JAVA\Head First JAVA code\shoot company>javac DotComBust.java
DotComBust.java:5: <identifier> expected
ArrayList<DotCom> dotComsList = new ArrayList<DotCom>();
^
DotComBust.java:47: ';' expected

}

for迭代器的用法，需要JDK1.5以上

请输入： java -version 看看信息是啥？
