in Java show me an example where the configproperties should save to

Here is an example where the config.properties file should be saved:

#config.properties file

#Database configuration
db.host=localhost
db.port=3306
db.name=mydatabase
db.username=myusername
db.password=mypassword

#Server configuration
server.host=localhost
server.port=8080
server.timeout=30000

In this example, the config.properties file should be saved in the root directory of the project.
