java - 使用 java 方法作为 scala 函数

Question

如果 Java 是一个 java 库，你能做这样的事情

class TryStuff(method:() => Any) {
   private val lib: Java = new Java

   val tryStuff:TryStuff = new TryStuff(lib.method)
}

有没有办法将 lib.method 转换为 scala 对象

Answer 1

val tryStuff:TryStuff = new TryStuff(x => lib.method(x))

或者更简洁

val tryStuff:TryStuff = new TryStuff(lib.method _)
