So, i put breakpoint to see content of countrycapitalmap and see that its size is 2.To handle collisions, hashmap uses several techniques.
This situation is commonly known as a hash collision, and various methods exist for handling it, with each one having their pros and cons.Whenever it is invoked on the same object more than once during an execution of a java application, the hashcode method must consistently return the same integer, provided no information used in equals comparisons on the.A collision happens when two different keys happen to have the same hash code, or two keys with different hash codes happen to map into the same bucket in the underlying array.
Feed the messagedigest one byte[] chunk at a time by calling md.update(bytes).2) from java 8 onwards, hashmap, concurrenthashmap, and linkedhashmap will use the balanced tree in place of linked list to handle frequently hash collisions.
This scenario can occur because according to the equals and hashcode contract, two unequal objects in java can have the same hash code.The choice between the two depends on various factors.However, why is the following code giving me different result?
Java's hashmap uses the separate chaining method for handling collisions:When you're done adding input bytes.

German champions Bayer Leverkusen will kick off their Bundesliga title defence and continue their unbeaten domestic streak away at local rivals Borussia Monchengladbach on Aug. 23, the league confirmed on Thursday as the fixture list was announced.

Gladbach were the only Bundesliga team that managed to stop Leverkusen scoring last season, holding Xabi Alonso's team to a 0-0 draw in their last meeting in January.
Leverkusen became the first team to win the Bundesliga title without losing a game.
Fixtures released by the league Thursday also include Bayern Munich starting their league season at Wolfsburg as they look to reclaim the Bundesliga title, and Champions League runners-up Borussia Dortmund playing Eintracht Frankfurt on the opening weekend.
Those games are set for either Aug. 24 or 25, with precise dates and times to be confirmed.
Leverkusen take on Bayern, Germany's most successful club historically, on the fifth matchday of the season from Sept. 27-29 at the Allianz Arena, and take them on at home between Feb 14-16.
Dortmund face Bayern in Der Klassiker on the final weekend of November at home, with the return fixture in Munich between April 11-13.
The first round of the German Cup starts the season Aug. 16 and there is the Super Cup between Leverkusen and Stuttgart the following day. Leverkusen won the German Cup last year as part of their infallible domestic term.
The only game they lost all season came in the Europa League final at the hands of Serie A's Atalanta.
