blocks|key|712685|text|问题与枚举无关(特别是)：在Java中，名称不能包含空格。尝试消除空格(使用大写来区分位)或使用下划线。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|712686|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

The problem has nothing (specifically) to do with enums: in Java, names can't have spaces. Try eliminating the space (using capitalization to tell the bits apart) or use underscores instead.

blocks|key|712742|text|我将继续并猜测为什么在名称中需要一个空格；因为您希望将其作为字符串引用。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|712743|所以要这样做：|712744|public+enum+MyEnum+{
++++INDIA("India"),
++++RUSSIAN("Russian"),
++++ENGLAND("England"),
++++NORTH_AMERICA("North+America");++++

++++private+String+name;

++++MyEnum(String+name)+{
++++++++this.name+=+name;
++++}

++++public+String+getName()+{
++++++++return+this.name;
++++}++++
}|code-block|syntax|javascript|712745|你可以考虑重写字符串。|712746|public+toString()+{
++++return+name;
}|712747|覆盖toString()的一个优点是，该字符串也可以在MyEnum+.valueOf(myString)中使用。因此，覆盖toString基本上会创建枚举值的HashMap。|712748|entityMap^0|0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|Q|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|R|8|@]|9|@]|A|$]]|$1|D|3|E|5|F|7|S|8|@]|9|@]|A|$G|H]]|$1|I|3|J|5|6|7|T|8|@]|9|@]|A|$]]|$1|K|3|L|5|F|7|U|8|@]|9|@]|A|$G|H]]|$1|M|3|N|5|6|7|V|8|@]|9|@]|A|$]]|$1|O|3|-4|5|6|7|W|8|@]|9|@]|A|$]]]|P|$]]

I'm gong to go ahead and guess why you want a space in the name; because you want to reference it as a string.

So do this:

<pre><code>public enum MyEnum {
 INDIA("India"),
 RUSSIAN("Russian"),
 ENGLAND("England"),
 NORTH_AMERICA("North America"); 

 private String name;

 MyEnum(String name) {
 this.name = name;
 }

 public String getName() {
 return this.name;
 } 
}
</code></pre>

You can consider overriding string.

<pre><code>public toString() {
 return name;
}
</code></pre>

An advantage of overriding toString() is that this string can also be used in MyEnum .valueOf(myString). So overriding toString basically creates a HashMap of the enum values.

blocks|key|497265|text|只需在枚举类中创建自己的类valueOf函数即可。用下划线替换空格。将枚举常量命名为"north_america("North+America")“。如果该方法找不到枚举，它只返回参数。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|497266|public++static+String+valueOfOrDefault(String+myValue)+{

just make your own valueOf like function in your enum class. Replace spaces with underscores. name your enum constants like this "north_america("North America")". If the method fails to find your enum it just returns the parameter. 

<pre><code>public static String valueOfOrDefault(String myValue) {
//replace space with underscore so it matches enum name
 String value=myValue.toUpperCase().replaceAll("\\s", "_");
 for(myEnum type : myEnum.class.getEnumConstants()) {
 if(type.name().equalsIgnoreCase(value)) {
 return type.toString();
 }
 }
 return myValue;
 }
</code></pre>

blocks|key|712875|text|我还介绍了自己的valueOf方法。但是我返回了枚举类型，并且我不必转换"checkString“|type|unstyled|depth|inlineStyleRanges|entityRanges|data|712876|例如，checkString就是“零用钱”。|712877|JournalType+journalType+=+JournalType.valueOfOrDefault(checkString);|code-block|syntax|javascript|712878|使用以下枚举：|712879|public+enum+JournalType+{

MISC_BILLING_AUTONUM("Misc+Billing+AutoNum"),
PRETTY_CASH("Petty+Cash"),
RECURRING_AP("Recurring+AP"),

GDS_NDS("GDS/NDS");

private+final+String+journalType;

JournalType(String+journalType)+{
++++this.journalType+=+journalType;
}

@Override
public+String+toString()+{

++++++++if(type.toString().equals(myValue))+{
++++++++++++return+type;

+++throw+new+IllegalArgumentException("JournalType+not+found");
}

I also introduced an own valueOf method. But I return with the Enum Type and I do not have to convert the &quot;checkString&quot;
checkString is &quot;Petty Cash&quot; for example.
<pre><code>JournalType journalType = JournalType.valueOfOrDefault(checkString);
</code></pre>
With the following enum:
<pre><code>public enum JournalType {

MISC_BILLING(&quot;Misc Billing&quot;),
MISC_BILLING_AUTONUM(&quot;Misc Billing AutoNum&quot;),
PRETTY_CASH(&quot;Petty Cash&quot;),
RECURRING_AP(&quot;Recurring AP&quot;),
GL_JOURNAL(&quot;GL Journal&quot;),
GDS_NDS(&quot;GDS/NDS&quot;);

private final String journalType;

JournalType(String journalType) {
 this.journalType = journalType;
}

@Override
public String toString() {
 return journalType;
}

public static JournalType valueOfOrDefault(String myValue) {
 for(JournalType type : JournalType.class.getEnumConstants()) {
 if(type.toString().equals(myValue)) {
 return type;
 }
 }
 throw new IllegalArgumentException(&quot;JournalType not found&quot;);
}

}
</code></pre>

Im working on java, I have created an enum as follows:

<pre><code>public enum myEnum
{
 india,
 russian,
 england,
 north America
}
</code></pre>

Above example gives errors while using space in the name of element (i.e. north America).
Any suggestions how to resolve above issue?

Java enum elements with spaces?

Java

我正在使用java，我创建了一个枚举，如下所示：public enum myEnum{    india,    russian,    england,    north America}上面的例子给出了在元素名称中使用空格时的错误(例如北美)。如何解决上述问题有什么建议吗？
