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

Java

public Vector TStatus;

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

	}

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:

Java

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

but it didn't work . any help please

Did you check the element is added to the vector properly? Are you trying to concatnate the ID and status and store it as a new string? Not able to understand TStatus.addElement(new String[]{ID, String.valueOf(Status)});

Solution 1

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

here is a simple solution

Java

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

I solved it :

Java

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