7) Usings Maps:

public static void main(String[] args) {

	Map<String, String> hashMap = new HashMap<String, String>();
	
	
	JexlContext context = new MapContext();

	context.set("map", hashMap);

	JexlEngine jexl = new JexlBuilder().create();

	JexlExpression e = jexl.createExpression("map.put(\"name\",\"JEXL TUTORIAL\")");
	e.evaluate(context);
	
	System.out.println("The value that is evaluated by jexl::\t" + hashMap.get("name"));

}

In the above example, we have took a simple HashMap(hashMap) and put it into jexlContext as “map”. Then jexlExpression “map.put("name","JEXL TUTORIAL")” will set the Key-value into hashMap. So, after evalution, the instance of hashMap is not empty.

Output: The value that is evaluated by jexl:: JEXL TUTORIAL
