new in java.
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(); } // switch } catch( Exception e ) { System.out.println( "exception:" + e.toString() ); System.out.println( e.getStackTrace().toString() ); } } // if ( null != tags && 0 <= row && row < tags.length ) return ""; }
