How to split a string using struts 2 tags? [duplicate]

问题

For Example:

String str="A:B";

I want to split A & B using Struts2 tags and display individually.

回答1:

Like @Alexander Cogneau says or with String::split function

here is an example:

java

public String[] getSplittedString() {
    String str = "A:B";
    return str.split(":");
}

interface

<s:iterator value="splittedString" status="someSplittedString" var="string">
    <s:textfield name="splittedString" value="%{#string}"></s:textfield>
</s:iterator>

回答2:

You can use the String.indexOf() method to get the ":" and then use String.substring() to split the string at certain indexes. So in your case that would be something like this:

String str="A:B";
int position = str.indexOf(':');

String beginning = str.substring(0, position-1);
String end = str.substring(position);
