I am setting thr value for RSSI column usinghistory.setRssi( tagHistory.getRssi() ); in the setData() method . For your convenience I am putting the setData() method and the code where I am displaying the values of RSSI column.

**********************************************************
public void setData( Tag _tag,WardenEvent[] _events,Device[] devices )
{
histories = null;
if( _tag != null )
{
History[] tagHistories = _tag.getHistories();

int k = 0;

I am generating data(e.g., 24, 16, 32, 38) in a row/column of a table. Now the data is displaying in random order. I want to display them in Descending order. Can anybody help me how to do this as I am new in Java development.

I am displaying the data using these lines of code:
case 1:
{
return history.getRssi();
}

From this Method:

public Object getValueAt( int row, int col )
{
if( null != histories && 0 <= row && row < getRowCount() )
{
try
{
History history =histories[row] ;
switch( col )
{
case 0:
return ( history.getCheckinTS().length() > 5 ) ? history.getCheckinTS().substring(5) : history.getCheckinTS();
case 1:
{
return history.getRssi();
}
case 2:
return history.getDeviceId();
...
