How do I convert a Java file to Swift using LetsConvert?

Why would I convert Java code to Swift?

Converting Java to Swift lets you reuse Android business logic in iOS apps without writing it twice. It also aligns with Apple's modern language features like optionals and protocol-oriented design, and helps maintain consistent behavior across platforms.

How does the converter handle Java-specific features like exceptions, optionals, and generics?

Checked exceptions are mapped to Swift's do-catch error handling, Java Optional becomes Swift Optional, and generics are preserved with Swift's generic syntax. Java static methods become Swift enum or struct static members where necessary. Some Android framework classes require manual stubbing, but the core logic remains intact.
