邏輯：迭代比較下一個值

Question

我正試圖對當前提交的內容進行比較。我有以下代碼：

<logic:iterate id="anItem" name="dataPage" property="filingsList" 
    indexId="myInd"> 
    <bean:define id="currentSubmissionId" type="java.lang.String" 
    name="anItem" property="denseRank"/> 

我想這樣做：

<logic:equal name="dataPage" property="currentSubmissionId" 
value="nextSubmissionId???"> 

    <img id="plus<%=rowCount%>" class="cursor" 
     src="<icis2:icisRes/>images/plus.gif" 
     onclick="toggle('<%=rowCount%>', this, 
     jQuery('#minus<%=rowCount%>'))"/> 

    <img id="minus<%=rowCount%>" class="cursor" 
     src="<icis2:icisRes/>images/minus.gif" onclick="toggle('<%=rowCount%>', 
     this, jQuery('#plus<%=rowCount%>'))" style="display: none;"/> 
</logic:equal> 

感謝，

Answer 1

1. Create a temp string variable to "", 
2. Store the current String here 
3. Iterate, and compare. 
4. As you iterate check if equal or not. 
5. If equal print else copy next string to the variable. 

這裏是代碼。

String[] someArrayOfStrings; // Store the Strings here. You can use ArrayList too. 
    String tempString = "";  // Recommend to use ArrayList. 

    for(int count=0; count<someArrayOfStrings.length-1; count++){ 
     tempString = someArrayOfStrings[count]; 

     if(tempString.equalsIgnoreCase(someArrayOfStrings[count+1])){ 
      System.out.print(tempString);  
     } 
    } 

讓我知道它是否有幫助。
