从j2me Vector检索数据 [英] retreiving data from j2me Vector

问题描述

你好，
我在Eclipse上使用j2me，我有以下代码:

Hello,
I am using j2me on Eclipse and I have this code :

public Vector TStatus;

    public void AddTRow(String ID,char Status){
    TStatus.addElement(new String[]{ID, String.valueOf(Status)});

	}

现在，我需要在代码中检索添加到向量TStatus中的值，以将其添加到stringBuffer，因此我按如下方式使用它:

now I need to retrieve the value added in the vector TStatus in my code to add it to stringBuffer, therefore I used it as below:

StringBuffer tBuilder = new StringBuffer();
     tBuilder.append(TStatus.elementAt(0)[1]);

但这没用.任何帮助请

but it didn''t work . any help please

推荐答案

您是否已将vector声明为vector< string []>可能就是问题

这是一个简单的解决方案

Have you declared your vector as vector<string[]> may be that is the problem

here is a simple solution

public Vector<string[]> TStatus = new Vector<string[]>();
	 
public void AddTRow(String ID,char Status){
    	TStatus.add(new String[] {ID, String.valueOf(Status)});
}

我解决了它:

I solved it :

StringBuffer tBuilder = new StringBuffer();
     tBuilder.append(((String[])TStatus.elementAt(0))[1]);
