Answer 1

with input "AAA 100\nBBB 200\nCCC 300\n"

after Bowling() you get:
al: [100, 200, 300]
players: {AAA=100, CCC=300, BBB=200}
ok

but after for() in main() you get:
al:[100, 200, 300, 300, 300, 300]
al is longer, because the input is "CCC 300"
and you add 300 at end of existed al 3x (!)

then in getWinner():
if (entry.getValue() == al.get(al.size() -1))
you compare every players.value with 300,
all tests are false because you compare Objects and not their values (!)

use this instead
if (entry.getValue() .equals ( al.get(al.size() -1)) ) {

is this answer to your question?

Answer 3

I converted the hashmap into two arraylists one for keys and the other one for values. Using the I found out the maximum value among the values and used that to find its corresponding key.
