Example 1
package com.example;

}
}

v8.registerJavaMethod(new Printer(), "print", "print", new Class<?>[]{String.class});

}
}
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");

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