Can somebody explain, why do we have to implement hashCode() and equals() method everytime we write a new class? Its a good practice to write hashCode() and equals() for a new class?
How Does hashcode() works in hashMap?
- Why does TreeSet sort like?
Entries

"12. Hello twelve"
"1. Hello One"
in following manner
"1. Hello One"
"102. Hello one o two"

Thanks in Advance.
