Both types allow you to have key and values configurations.

key=value

Ini file has sections enclosed in square brackets [] and properties do not allow sections.

[dev]
isProd=false
[prod]
isProd=true

In the case of properties, values with duplicate keys are overridden. if the key value is repeated multiple times, the last key value is considered

name=john
name=Eric
name=Mark

During reading, the name value is considered as the mark.
