Possibility to call a Java static method in Kotlin

Question

Suppose we have a Java static method:

//Java code
public static void printFoo() {
    System.out.println("foo");
}

It is possible to call that method in Kotlin?

Answer 1

Yes, you can. Java code:

public class MyJavaClass {
    public static void printFoo() {
        System.out.println("foo");
    }
}

Kotlin code:

fun main(args: Array<String>) {
    MyJavaClass.printFoo()
}

So easy =)

Answer 2

The answer from 0wl is generally correct.

I just wanted to add that some of the Java classes are mapped to special Kotlin classes. In this case you must fully qualify the Java class for this to work.

Example:

fun main(args: Array<String>) {
    println(java.lang.Long.toHexString(123))
}
