Still about sorting TreeMap
Why this is not working?
I want to order by the first index of the value:
Map map =new TreeMap( ) ;
map.put("115.393.028-57",new Object[]{"FRANK","VALLEY"} ) ;
map.put("105.393.028-57",new Object[]{"JOHN","SMITH"} ) ;
map.put("112.393.028-57",new Object[]{"KYLE","BREAT"} ) ;
Set set =new TreeSet(new Comparator(){
publicint compare( Object o1, Object o2 ){
Map.Entry e1 = ( Map.Entry ) o1;
Map.Entry e2 = ( Map.Entry ) o2;
Object[] d1 = ( Object[] ) e1.getValue( ) ;
Object[] d2 = ( Object[] ) e2.getValue( ) ;
String name1 = (String)d1[0];
String name2 = (String)d2[0];
return name1.compareTo( name2 ) ;
}
}) ;
set.addAll( map.entrySet( )) ;
for ( Iterator iter = set.iterator( ) ; iter.hasNext( ) ; ){
Map.Entry entry = ( Map.Entry ) iter.next( ) ;
System.out.println( entry.getKey( ) +" = " + entry.getValue()) ;
}
