hashkey

A simple implementation that uses object based on custom classes as HashMap key.

The hash code generation and equality check is done via Apache Commons Lang HashCodeBuilder and EqualsBuilder.

Sample Console Output

Keys equal? [true]
Hash codes equal? [true]
==============
Validate whether generated hash codes are always same:
Hash code [dataKey1]: 70329913
Hash code [dataKey1]: 70329913
Hash code [dataKey1]: 70329913
Hash code [dataKey2]: 70329913
Hash code [dataKey2]: 70329913
Hash code [dataKey2]: 70329913
==============
Added data with dataKey1.
==============
Query data with dataKey2:
[1000, 2000, 3000, 4000, 5000]
==============
Replaced data with dataKey2:
[5000, 4000, 3000, 2000, 1000]
==============
Query data with dataKey1:
[5000, 4000, 3000, 2000, 1000]
