java - el表达式 if else

Question

jsp模板标签,有if else的写法吗?
网上查了说这样写

刚学java,确定下只能这样写吗?感觉好别扭!
或者说有没有其他写法,
如果只有这样的写法,
那么

if(){

}elseif(){

}elseif(){
}

这样的情况怎么表示?

Answer 1

means this

 <c:choose>
    <c:when test="${1==2}">
             0001
    </c:when>
       <c:otherwise>
          <c:choose>
            <c:when test="${1==3}">
             0002
             </c:when>
            <c:otherwise>
             0003
             </c:otherwise>
        </c:choose>
     </c:otherwise>
</c:choose>

Answer 2

    if(){
    
    }elseif(){
    
    }elseif(){
    }

Isn’t this pattern just three c:ifs

Answer 3

It doesn’t feel awkward if you use it too much. It only feels awkward if you use <% %> to insert a piece of java code
