// sample to demonstrate calling Function.prototype.bind on Java methods.

var DoubleStream = java.util.stream.DoubleStream;
var r = new java.util.Random();

// bind "this" for nextGaussian method of Random class
var next = Function.bind.call(r.nextGaussian, r);

// next is used as no argument "function"
