How to call each other in Scala and Java methods

Today, I will talk to you about how to call each other in Scala and Java methods. Many people may not know much about it. In order to make you understand better, the editor has summarized the following contents for you. I hope you can get something according to this article.

1. The first is the static method.

Object ScalaObjectDemo extends App {println ("hello zhaojun i miss you very much"); def say (name:String) {println (name)} / * first call the java method * @ return * / def say3 (): Int = {println ("here is the method of scala") var tmp=JavaDemo.say2 ("4"); println (tmp); tmp}}

2. The method of calling Scala in JAVA

Public class JavaDemo {public static void main (String [] args) {ScalaObjectDemo.main (new String [] {}); ScalaObjectDemo.say ("zhaojun"); / / Test repeated method calls int say3 = ScalaObjectDemo.say3 (); System.out.println (say3);} public static int say2 (String age) {System.out.println ("here is java's static method" + age) Return Integer.parseInt (age);}}

Non-static methods in 3.Scala

Class ScalaClassDemo {def hi (name:String): Int= {println (name) 1}}

Calls in 4.Java

Int zhaojun = new ScalaClassDemo (). Hi ("zhaojun"); System.out.println (zhaojun); after reading the above, do you have any further understanding of how to call each other in the Scala and Java methods?
