Hello aspirant

hope you are doing well and safe. With reference to your query,  I would glad inform you that both are languages very good and interesting to opt for coding . If you want to prepare for placements ,then go for java clear concepts and fundamental and then shifting of lanuages wont take time as python syntaxes are quite easy but yes after doing java your concepts will be stronger

If you have any other doubt then you can always reach us to clear them :)

we are always available to help you out and guide you

Thankyou
