Added 25+ Java Practice Questions of Arrays and Strings

[aasthaanand09]

Hello @fineanmol,

I've created a new directory titled 'Practice Questions Java.' It contains over 25 essential questions covering Arrays, Strings, Searching, and Sorting, which are pivotal from a conceptual perspective.

Could you please merge this directory into the repository? This addition will provide valuable resources for the audience, allowing them to benefit from these materials.

Thank you for your attention to this request.

Best regards, @aasthaanand09

i think there is some problem in Owners repo or you haven't fulfilled the contribution criteria so it is rejected.
