MAP :

x = [ 1 : "harish" , 2 : "viv" ]
public function() {
println x.1;
}
function()
​

brings error 

startup failed:
Script1.groovy: 3: unexpected token: 1 @ line 3, column 11.
   println x.1;
             ^

1 error

whereas

x = [ id : "harish" , 2 : "viv" ]
public function() {
println x.id;
}
function()

works fine giving output  harish

To solve the first problem we faced when we had integer as key
is


x = [ 1 : "harish" , 2 : "viv" ]
public function() {
println x.get(1);
}
function()
​
works fine giving output : harish

Similarly
x = [ id : "harish" , 2 : "viv" ]
public function() {
println x.get(id);
}
function()

flings error 

groovy.lang.MissingPropertyException: No such property: id for class: Script1
 at Script1.function(Script1.groovy:3)
 at Script1.run(Script1.groovy:5)

But
x = [ id : "harish" , 2 : "viv" ]
public function() {
println x.get("id");
}
function()

works fine giving output as harish
