I have a long Map (int, int[] ) ;
I use map.entrySet() and it returns me the Set view of my map
Map <Integer, ArrayList<Integer>>res = function() ;
System.out.println( res.entrySet() ) ;
i want to show every entry on new line:
[1=[1, 47, 432, 433, 527, 678, 679, 680, 820, 904],
2=[1, 31, 47, 66, 118, 139, 194, 195, 196, 217]
3 = [.............],
10 = [..............],
but instead i have it all printed on one line(it's very long):
[1=[1, 47, 432, 433, 527, 678, 679, 680, 820, 904], 2=[1, 31, 47, 66, 118, 139, 194, 195, 196, 217], 3=[123,23,.....],............
How to make my set print each key-value pair on new line? or is it by default comma after comma and in one line?
Just iterate over the EntrySet of the Map and print
for(Map.Entry entry : res.entrySet()){
System.out.println(entry);
//System.out.println(entry.getKey() + "=[" + entry.getValue() + "]");
}
