hashmap - How to get the size of String java.util.Map.Entry.getKey() in java? -

i tried options not required output.

the question how size of m.getkey()

i tried m.getkey().length ,m.getkey().size not find.

system.out.print("\n duplicate words: "); for(map.entry<string, integer> m:  map.entryset()){ if(m.getvalue()>tostringarray.length-1) ); system.out.print(m.getkey() + " "); } 

the output

( hi output)

the output needed

(5) //hi output total count 5

suggestions welcomed.

i beginner java

here full code

you try bellow count words in key:

string keys = ""; for(map.entry<string, integer> m:  map.entryset()){  if(m.getvalue()>tostringarray.length-1)     keys = keys + " " + m.getkey(); } system.out.print(keys.trim().split("\\s+").length);
