public class BarChart extends Applet
{
    int n =0;
    String label[];
    int value[];
    String EndLabel[];
    @Override
    public void init()
    {
        try
        {
            n= Integer.parseInt(getParameter("columns"));
            label = new String[n];
            value = new int[n];
           EndLabel = new String[n];
            
            label[0] = getParameter("label1");
            label[1] = getParameter("label2");
            label[2] = getParameter("label3");
            label[3] = getParameter("label4");
            
            value[0] = Integer.parseInt(getParameter("c1"));
            value[1] = Integer.parseInt(getParameter("c2"));
            value[2] = Integer.parseInt(getParameter("c3"));
            value[3] = Integer.parseInt(getParameter("c4"));
            
            EndLabel[0] = getParameter("Label1");
            EndLabel[1] = getParameter("Label2");
            EndLabel[2] = getParameter("Label3");
           EndLabel[3] = getParameter("Label4");
        }
        catch(NumberFormatException e)
        {
        }
    }
    @Override
           public void paint(Graphics g)
        {
        for(int i=0;i<n;i++)
        {
            g.setColor(Color.red);
            g.drawString(label[i], 20, i*50+30);
            g.fillRect(60, i*50+10, value[i], 40);
           g.drawString( EndLabel[i],60+value[i]+10, i*50+30);
            
        }
    }
}

EndLabel[0] = getParameter("Label1");
            EndLabel[1] = getParameter("Label2");
            EndLabel[2] = getParameter("Label3");
           EndLabel[3] = getParameter("Label4");
<PARAM NAME="EndLabel1" VALUE="110">
<PARAM NAME="EndLabel2" VALUE="150">
<PARAM NAME="EndLabel3" VALUE="100">
<PARAM NAME="EndLabel4" VALUE="170">

You have getParameter looking for the parameter that goes with "Label1", etc. rather than "EndLabel1", etc.

i changed the code and it works now

EndLabel[0] = String.valueOf(value[0]);
EndLabel[1] = String.valueOf(value[1]);
EndLabel[2] = String.valueOf(value[2]);
EndLabel[3] = String.valueOf(value[3]);
