this method is very important as it decides whether the size of the map is needed to increase or not if it is needed , it increases the size in double if size is equal to map.length concode_field_sep Map<K,V>[] map concode_elem_sep int size concode_field_sep int size concode_elem_sep void printMap concode_elem_sep V get concode_elem_sep void put
void function ( ) { if ( size == map . length ) { int loc0 = map . length * 2 ; map = Arrays . copyOf ( map , loc0 ) ; } }
