我的java程序中出现了一个非常奇怪的错误.此代码显示没有错误:
buttonPlay.addListener(new ClickListener(){
public void clicked(InputEvent event, float x, float y) {
/*public GameScreen(Create create) {
this.create = create;
}*/
}
});
但是,如果我删除评论,请Eclipse说明有两个错误:
我应该插入一个"}"来完成"public void clicked"的方法体.
我应该删除代码的最后一个"}".
所以" public GameScreen(Create create)"会产生问题,Eclipse突然间不再知道块的开始和结束位置(我认为).
我对此没有任何解释,并且对每个答案都很高兴.
如果将指针设置为null,则删除该变量.它不能再使用了,它不再需要您的存储空间.指针的名称代表其值.它的价值永远&someVariable.我可以这样做:&someVariable = null;
[编辑]当我写这篇文章时,我对C++很陌生,所以我有多种误解.
要删除指针,您必须delete ptr;而不是通过将其设置为null ptr = nullptr;.
&someVariable 是一个右值,因此无法分配任何东西.
它是0,NULL或者nullptr不是null.
总而言之,你永远不应该delete &anything;,即使你很幸运,它也会编译.只需删除分配时获得的指针即可anything.
所以Dreamweaver告诉我,我在第5,8,10和12行有语法错误.但我不明白为什么？
<?php
if(isset($_POST['submit'])) (
$msg = 'Name: ' .$_POST['FirstName'] .$_POST['LastName'] ."\n"
.'Email: ' .$_POST['Email'] ."\n"
.'Message: ' .$_POST['Message'];
mail('email@me.com', 'Message from website', $msg);
header('location: contact-thank-you.php');
)
else (
header('location: contact.php');
exit(0);
)
)
?>
我在return语句中无法理解这种语法.我不确定它是否是Swift 2.0中的新功能,但它是什么？和:意思是？这个问号是否可选,即使间隔？我很困惑,来自Objective-C背景.
private func doContainsUser(user: User) -> Bool {
let isInverted = setOfDiff.contains(user)
let wasInitiallyAdded = setOfCircleUsers.contains(user)
//What does the ? and the : mean?
return isInverted ? !wasInitiallyAdded : wasInitiallyAdded
}
我有这么长的JQuery和太多的引号.它让我沮丧:
$('("<img>", { src: oembed.thumbnail_url, width:200 }).children("img").wrap("<div class="thumbnail_border" />")').insertBefore("div#heard_div");
所以问题是这条线的正确语法是什么.
