Example 1

package com.example;

import com.eclipsesource.v8.V8;

public class EclipseCon_snippet5 {

    public static class Printer {
        public void print(String string) {
            System.out.println(string);
        }
    }

    public static void main(String[] args) {
        V8 v8 = V8.createV8Runtime();
        v8.registerJavaMethod(new Printer(), "print", "print", new Class<?>[]{String.class});
        v8.executeVoidScript( "print('Hello, World!');" );
        v8.release(true);
    }
}

Example 2

public static void main(String[] args) {
    V8 v8 = V8.createV8Runtime();
    int x = (Integer) v8.executeScript("var func = x => x * x; func(5);");
    System.out.println(x);
    v8.release();
}

Example 3

public static void main(String[] args) {
    V8 runtime = V8.createV8Runtime();
    int result = runtime.executeIntegerScript(""
        + "var hello = 'hello, ';\n"
        + "var world = 'world!';\n"
        + "hello.concat(world).length;\n");
    System.out.println(result);
    runtime.release();
}

Example 4

V8Object player1 = new V8Object(runtime).add("name", "John");
V8Object player2 = new V8Object(runtime).add("name", "Chris");
V8Array players = new V8Array(runtime).push(player1).push(player2);
hockeyTeam.add("players", players);
player1.release();
player2.release();
players.release();

var hockeyTeam = {
    name      : 'WolfPack',
    players   : [],
    addPlayer : function(player) {
        this.players.push(player);
        return this.players.size();
    }
}

V8Array parameters = new V8Array(runtime).push(player1);
int size = hockeyTeam.executeIntegerFunction("addPlayer", parameters);
parameters.release();

    V8Object chorke   = runtime.getObject("Chorke");

    System.out.println(academia.getString("$class"));

    academia.release();
    chorke.release();
