小编Aks*_*tha的帖子

public class BroadcastTest extends Activity {
BroadcastReceiver receiver;

/** Called when the activity is first created. */

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    try{
    receiver=new Receiver(this);
    registerReceiver(receiver,new IntentFilter(Intent.ACTION_CALL_BUTTON));
    }catch(Exception e){
        Log.d("error",e.getMessage());
    }
  }
}

和另一堂课

public class Receiver extends BroadcastReceiver{
public Receiver(BroadcastTest broadcastTest) {
    // TODO Auto-generated constructor stub
}

@Override
public void onReceive(Context arg0, Intent arg1) {
    // TODO Auto-generated method stub
    Log.d("Fired","Hi");
}
}

当按下呼叫按钮时,接收器类的onReceive方法应该被调用吗？如果是,那么它就没有调用.我在这里做错了什么.按下呼叫按钮时我没有在logcat中看到任何东西.谢谢提前

我在我的java bean中使用\n,并且控制台中的变量输出正确显示.虽然从bean获取此值到JSF \n似乎不起作用.......任何人都可以建议我如何使用JSF中的工作.

我在java中有以下链表程序,除反向链表功能外,它工作正常.我错过了什么？

public class LinkedList {

private Link first;

public LinkedList()
{
    first = null;
}
public boolean isEmtpy()
{
    return(first==null);
}

public void insertFirst(int id, double dd)
{
    Link newLink=new Link(id,dd);
    newLink.next=first;     //new link --> old first
    first =newLink;         //first --> newLink
}
public Link deleteFirst()
{
    Link temp=first;
    first=first.next;
    return temp;
}
public void displayList()
{
    Link current=first;
    System.out.println("List (first-->last)");
    while(current!=null)
    {
        current.displayLink();
        current=current.next;
    }       
    System.out.println(" ");
}
public Link find(int key)
{
    Link current=first;

    while(current.iData!=key)
    {
        if(current.next==null)
            return …

我有一个动态创建的复选框的jsp页面.当我们选中复选框时,变量将获取相应的emp id.

例如:我检查了emp id 2和4的相应复选框,然后我会得到一个2,4的警告框.

现在我如何一个接一个地删除逗号并传递值,因为我想在下一个jsp中提取员工的相应详细信息.一世

我正在寻找Java中的代码来从整数之间删除逗号.

我从one.jsp获得gra值如下

<script language="javascript">
function gotoAddPanelAction(elem)
{ 
var st=elem.value;
if(st!="")
{
Popup=window.open('SelectInterviewPannel2.jsp?gra='+st,'Popup','toolbar=no,location=no,status=no,menubar=no,scrollbars=yes,resizable=yes',400,400);
}
else
{
validateForm(document.frm);
}
}
</script>

我正在重新检查SelectInterviewPannel2.jsp中的值,如下所示

<td width="60%" class="txt-lable">
 <Select name="grade" ><option value="" selected>Select</option>
 <%
String gra = request.getParameter("gra");
 if(gra.value=="Level 1") {
%>
<option value="E1">E1</option><option value="E2">E2</option><option value="E3">E3</option><option value="E4">E4</option></select>
<% } else  {%>
 <option value="M1">M1</option><option value="M2">M2</option></select>
<% } %>
 </td>

我的问题是在SelectInterviewPannel2.jsp if if语句没有执行.我只得到选择下拉框而没有值.

在jsp中

<table width="100%" id='table1'  border="0" cellspacing="2" cellpadding="2">
    <tr class="tab-highlighted-2">
        <td class="tab-highlighted-2" width="10%">
          <div align="left">Project ID</div>
        </td>
        <td class="tab-highlighted-2" width="10%">
          <div align="left">Project Name</div>
        </td>
        <td class="tab-highlighted-2" width="20%">
          <div align="left">Cost Center</div>
        </td>
        <td class="tab-highlighted-2" width="20%">
          <div align="left">Manager</div>
        </td>
    </tr>
  <tr class="bg-row1">
  <c:forEach items="${resultList}" var="resultList"> 
        <td class="td-highlighted-2">
         <div align="left"><a href="UpdateProject.html">${resultList.Projid}</a></div>
        </td>
        <td class="td-highlighted-2">
          <div align="left">${resultList.Projname}</div>
        </td>
        <td class="td-highlighted-2">
          <div align="left">${resultList.Cost}</div>
        </td>
        <td class="td-highlighted-2">
          <div align="left">${resultList.Manager}</div>
        </td>  
    </tr>  
    </table> 

在道

public final class SearchProjDAO   
{ 
    private static InitialContext context;  
    String CLASS_NAME="DBConnectionFactory";  

    public ArrayList  submitProjectDetails(SearchProjVO …
