initializing a Guava ImmutableMap

Question

Guava offers a nice shortcut for initializing a map   However I get the following compiler error  Eclipse Indigo  when my map initializes to nine entries    The method of K  V  K  V  K  V  K  V  K  V  in the type ImmutableMap is not applicable for the arguments   String  String  String  String  String  String  String  String  String  String  String  String  String  String  String  String  String  String   ImmutableMap lt String String gt  myMap   ImmutableMap of           key1    value1             key2    value2             key3    value3             key4    value4             key5    value5             key6    value6             key7    value7             key8    value8             key9    value9               The message appears to say that      An ImmutableMap has a maximum size of four pairs of key value    Obviously  this cannot be the case but I can t figure out what to do to increase the size of my initializer   Can someone tell me what is missing

put  has been deprecated  refrain from using it  use  of instead  ImmutableMap lt String  String gt  myMap   ImmutableMap of       city1    Seattle        city2    Delhi

if the map is short you can do   ImmutableMap of key  value  key2  value2         up to five k-v pairs   If it is longer then   ImmutableMap builder       put key  value      put key2  value2                build

Notice that your error message only contains five K  V pairs  10 arguments total  This is by design  the ImmutableMap class provides six different of   methods  accepting between zero and five key-value pairings  There is not an of      overload accepting a varags parameter because K and V can be different types   You want an ImmutableMap Builder   ImmutableMap lt String String gt  myMap   ImmutableMap  lt String  String gt builder        put  key1    value1         put  key2    value2         put  key3    value3         put  key4    value4         put  key5    value5         put  key6    value6         put  key7    value7         put  key8    value8         put  key9    value9        build
