Java 相当于 Kotlin 的 Function0 和 Function1 是什么？

Question

I was trying to implement Github Link library in my java project. And I don't want to use Kotlin in my project, so I was custom coding the whole library into Java. Any help appreciated. It's hard to convert Kotlin to Java rather the opposite. I have worked with decompiling Kotlin Bytecode, which somewhat helps you to convert it into Java. And that's where it's getting confusing where Function0 and Function1 comes into picture. I also saw this Question on Stackoverflow . But I can't use Kotlin in my project.

Answer 1

The equivalent are the Functional Interfaces Supplier and Function , respectively

They have the same signatures, and are SAM (Single abstract methods), so they are replaceable by an in-line lambda.
