Question

how do i access an array by its keys in java

In this case i want the structure to be like this,

options[{"value":"0","label":"zero"},{"value":"1","label":"one"},
   {"value":"2","label":"two"}]

Here if i want to access options[1].value should give me 1 and options[2].label should give me two.

How can i achieve this with Map<string><string[]>?

Also Can i pass “options” array as one of the keys in my hash map

     protected Map<String, String[]> getValueProperties(int view, Field field) {
 Map<String, String> properties = new   HashMap<String,String[]>();             
        properties.put("options", []);
        return properties
    }

Answer 1

Create a class as follows

class Entry
{
    int value;
    string label; 
    public Entry(int val, string lbl)
    {
        this.value = val;
        this.label = lbl;
    }
}

Now create you options array as follows:

Entry[] options = new Entry[3];
options[0] = new Entry(0, "zero");
options[1] = new Entry(1, "one");
options[2] = new Entry(2, "two");

if i want to access options[1].value should give me 1 and options[2].label should give me two

Now, options[1].value will give you 1.
