You could use a ternary like so (but it's ugly, and you still need a close() or a flush()).

<pre><code>// Construct this constant date format elsewhere, and save the referene!
DateFormat df = new SimpleDateFormat("MM/dd/yy HH:mm:ss");
// This ternary is ugly, but possible.
out.println((config.getBoolean("storecommands.use-time") ? 
 "[" + df.format(new Date()) + "]: " : "")
 + e.getMessage());
out.close(); // &lt;-- might prefer flush() there.
</code></pre>

"["+%2B+(new+SimpleDateFormat("MM/dd/yy+HH:mm:ss")).format(new+Date())+
%2B+"]:+"+%2B+e.getMessage())+:+e.getMessage());

out.close();|code-block|syntax|javascript|3413425|但这可能是我见过的最糟糕的事情，您不应该在生产代码中这样做。如果你这么做，我会知道，我们会找到你的。|3413426|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|K|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|L|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|M|8|@]|9|@]|A|$]]|$1|I|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|J|$]]

Not one line, but two lines:

<pre><code>out.println(config.getBoolean("storecommands.use-time")) ? 
"[" + (new SimpleDateFormat("MM/dd/yy HH:mm:ss")).format(new Date()) 
+ "]: " + e.getMessage()) : e.getMessage());

out.close();
</code></pre>

But that is possibly the worst thing I've ever seen and you should never ever do this in production code. If you do I will know, and we will find you.

blocks|key|3413443|text|您可以在这里使用条件运算符，但是它可能会以可读性为代价，所以我会重新考虑。无论如何，你都可以：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3413444|boolean+b+=+config.getBoolean("storecommands.use-time");
String+message+=+e.getMessage();++++

out.println(b+?+
++++++++++++++++"["+%2B+(new+SimpleDateFormat("MM/dd/yy+HH:mm:ss")).format(new+Date())+%2B+"]:+"+%2B+message
++++++++++++++:
++++++++++++++++message);|code-block|syntax|javascript|3413445|把这些都写在一行上是个坏主意，所以我把它分成几行。|3413446|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|K|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|L|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|M|8|@]|9|@]|A|$]]|$1|I|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|J|$]]

You can use the conditional operator here, but it'll probably come at the cost of readability, so I would reconsider. In any case, you can do:

<pre><code>boolean b = config.getBoolean("storecommands.use-time");
String message = e.getMessage(); 

out.println(b ? 
 "[" + (new SimpleDateFormat("MM/dd/yy HH:mm:ss")).format(new Date()) + "]: " + message
 :
 message);
</code></pre>

Writing this all on one line is simply a bad idea, so I've split it up to span multiple lines.

blocks|key|3441834|text|private+String+foo(boolean+b)+{
++++if(b)+{
++++++++return+new+String("["+%2B+(new+SimpleDateFormat("MM/dd/yy+HH:mm:ss")).format(new+Date())+%2B+"]:+");
++++}+else+{
++++++++return+"";
}|type|code-block|depth|inlineStyleRanges|entityRanges|data|syntax|javascript|3441835|然后只需这样做：|unstyled|3441836|out.println(foo(config.getBoolean("storecommands.use-time")+%2B+e.getMessage());
out.close();|3441837|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|K|8|@]|9|@]|A|$B|C]]|$1|D|3|E|5|F|7|L|8|@]|9|@]|A|$]]|$1|G|3|H|5|6|7|M|8|@]|9|@]|A|$B|C]]|$1|I|3|-4|5|F|7|N|8|@]|9|@]|A|$]]]|J|$]]

<pre><code>private String foo(boolean b) {
 if(b) {
 return new String("[" + (new SimpleDateFormat("MM/dd/yy HH:mm:ss")).format(new Date()) + "]: ");
 } else {
 return "";
}
</code></pre>

Then simply do this:

<pre><code>out.println(foo(config.getBoolean("storecommands.use-time") + e.getMessage());
out.close();
</code></pre>

blocks|key|3413502|text|是的，但可读性比长度更重要(在合理的数量)。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3413503|此外，我还使用了一个三元条件，它将注入格式化的date+或字符串为空，从而允许我们自由地添加e.getMessage一次。|offset|length|style|BOLD|CODE|3413504|out.println((config.getBoolean("storecommands.use-time")+?+"["+%2B+(new+SimpleDateFormat("MM/dd/yy+HH:mm:ss")).format(new+Date())+%2B+"]:+"+:+"")+%2B+e.getMessage());

Yes, But readability is more important than length (In reasonable amount).

Additionally, I've used a ternary condition that will inject the formatted date OR string empty, thus allowing us to freely add <code>e.getMessage</code> Once.

<pre><code>out.println((config.getBoolean("storecommands.use-time") ? "[" + (new SimpleDateFormat("MM/dd/yy HH:mm:ss")).format(new Date()) + "]: " : "") + e.getMessage());
out.close();
</code></pre>

I'm wondering if it's possible to write this in one-liner form.

<pre><code>if (config.getBoolean("storecommands.use-time")) {
 out.println("[" + (new SimpleDateFormat("MM/dd/yy HH:mm:ss")).format(new Date()) + "]: " + e.getMessage());
 else {
 out.println(e.getMessage());
 }
 out.close();
</code></pre>

I thought maybe something like this:

<pre><code>(config.getBoolean("storecommands.use-time")) ? first : last;
</code></pre>

but then I remembered that that only works for setting variables.

Does anyone know if something like the first block of code can be written in one line w/o brackets, etc.

Is there a shorter way to write this?
