Hello everyone I have an arraylist showing up as [MCA, MCB, COMM, DMISA] on the jsp.
Im calling it on the jsp:
<td>${bean.CodesNames}</td>
In the bean the getter is:
public void setCodesNames(ArrayList<String> CodesNames)
{
this.CodesNames = CodesNames;
}
How can I display this without the brackets?
You get the brackets because ArrayList#toString() is implicitly called, in order to turn the list into a printable string. You can fix this by printing the list yourself in the JSP:
<c:forEach items="${CodesNames}" var="item" varStatus="status">
${item}<c:if test="${!status.last}">,</c:if>
</c:forEach>
or with a bean getter than returns a string:
public String getCodesNamesAsString()
{
// using a Guava Joiner
return Joiner.on(",").useForNull("null").join(getCodesNames());
}
(See the Joiner JavaDocs if you're not familiar with Guava.)
Add another getter method:
public void getCodesNamesFormatted()
{
StringBuilder sb = new StringBuilder();
for (String codeName : CodesNames) sb.append(codeName).append(',');
return sb.deleteCharAt(sb.length());
}
And call it from JSP:
<td>${bean.codesNamesFormatted}</td>
You need to iterate it. Don't rely on toString.
<td>
<c:forEach var="name" varStatus="stat" items="${bean.codesNames}">
<c:out value="${name}"/>
<c:if test="${stat.index < fn:length(bean.codesNames) - 1}">
<c:out value=","/>
</c:if>
</c:forEach>
</td>
PS: The <c:out/> is optional here.
You can implement getter which makes formatting you need
public String getCodesNamesFormatted()
{
// format as you like
}
Then use it
<td>${bean.codesNamesFormatted}</td>
This string ([MCA, MCB, COMM, DMISA]) is generated by method toString() of class Array. You need to create own code which will iterate over array elements and print them one-by-one. Or of course you can use dirty way of replaceAll. See code below for both ways:
1)
<% for( String arrayItem : myArray ) { %>
<%= arrayItem %>,
<%}%>
2)
<%=myArray.toString().replaceAll("\[|\]","")%>
