在 Kotlin 中使用 setter 实现 Java getter 接口

Question

I have a java interface:

    public interface TestInterface {
           String getName();
    }

I have a kotlin class:

class TestImpl(private var name: String = "name"): TestInterface {
    override fun getName(): String = name
}

But if I also want the setter method of the name field,

class TestImpl(private var name: String = "name"): TestInterface {
    override fun getName(): String = name
    // I don't want to write a setter like this
    fun setName(n: String) {
        this.name = n
    }
}

What better way can I do? Thanks.

You could use

class TestImpl(@get:JvmName("getName_") var name: String = "name"): TestInterface {
    override fun getName(): String = name
}

Then you access it as x.name / x.name = ... from Kotlin, and x.getName() / x.setName(...) from Java. Unfortunately, you also have getName_() in Java, but you don't have to use it.
