title	load function

// can load script from files, URLs

load("foo.js"); // loads script from file "foo.js" from current directory
load("http://www.example.com/t.js"); // loads script file from given URL

// loads script from an object's properties. 

// Object should have "script" and "name" properties.
//     "script" property contains string code of the script. 
//     "name" property specifies name to be used while reporting errors from script
// This is almost like the standard "eval" except that it associates a name with
// the script string for debugging purpose.

load({ script: "print('hello')", name: "myscript.js"})

// load can also load from pseudo URLs like "nashorn:", "fx:"., "classpath:" 

// "nashorn:" pseudo URL scheme
// for nashorn's built-in scripts. "fx:" pseudo URL scheme for JavaFX support scripts

// load nashorn's parser support script - defines 'parse'
// function in global scope

load("nashorn:parser.js"); 

// load Mozilla compatibility script - which defines global functions
// like importPackage, importClass for rhino compatibility.

load("nashorn:mozilla_compat.js");

// "fx:" pseudo URL scheme for JavaFX support scripts
// "classpath:" pseudo URL scheme to load scripts from jjs classpath jars and directories

load("classpath:foo.js"); // load the first foo.js found in jjs -classpath dir

title	$EXEC example with $OUT usage

var Arrays = Java.type("java.util.Arrays")

// use curl to download JSON weather data from the net
var str = `curl http://api.openweathermap.org/data/2.5/forecast/daily?q=Chennai&amp;mode=json&amp;units=metric&amp;cnt=7`

// parse JSON
var weather = JSON.parse($OUT)

// pull out humidity as array
var humidity = weather.list.map(function(curVal) {
    return curVal.humidity
})

// Stream API to print stat
print("Humidity")
print(Arrays["stream(int[])"](humidity).summaryStatistics())

// pull maximum day time temperature
var temp = weather.list.map(function(curVal) {
    return curVal.temp.max
})

// Stream API to print stat
print("Max Temperature")
print(Arrays["stream(double[])"](temp).summaryStatistics())
