Examples

Dictionary d;
print(d); // {}

Dictionary d = new Dictionary();
print(d);  // {}

Dictionary d = {"key1": 1, "key2": 2};
print(d);   // {"key1": 1, "key2": 2}

Dictionary d = {};             // Not work, will cause error.

Dictionary d1 = new Dictionary("key_01","value01");
print(d1);                                                                      // {"key_01": sdasd}

print(d1);                               //          {"3": hello3333, "key_01": value01, "key_02": 2222, "key_03": {happy,48,{funny,sad,88}}}

print(d1.get_Item(3));                                                          // hello3333
print(d1.set_Item("key01",1111));     
print(d1.set_Item(3,{3333,"string333"}));

print(d1.Values);                                                               // {value01,2222,{3333,string333},{happy,48,{funny,sad,88}},1111}

print(d1.Remove(3));                                                            // {3333,string333}

Dictionary d = {
  "key01": "value01",
  5: "value05"
}; 
print(d["key01"]);       // another way to get the values of keys
print(d[5]);             // another way to get the values of keys

//Example for using d.Inc("key") to increase value of the key up to 1, if the key not exist, create the key with value 1
Dictionary d = {"key1": 1, "key2": 2};
d.Inc("key2");// key2 existed, so increate value of key2 to 1 (2->3)
print(d);//{"key1": 1, "key2": 3}
d.Inc("key3");// key3 not exist, so add key3 to d with value 1
print(d);//"key1": 1, "key2": 3, "key3": 1}
