Description

String with length 1, if assigned to int variable, assigns the ascii value. String with more than 1 length throws GroovyCastException

/*line 1  : case-1 */ char    c1 = '1'
/*line 2  : case-1 */ int     n1 = c1
/*line 3  : case-1 */ println "n1 = $n1" //prints ascii value of 1 :'n1 = 49'

/*line 4  : case-2 */ String  s2 = '1'
/*line 5  : case-2 */ int     n21 = s2
/*line 6  : case-2 */ int     n22 = s2 as int
/*line 7  : case-2 */ println "n21 = $n21" //prints 'n21 = 49'
/*line 8  : case-2 */ println "n22 = $n22" //prints 'n22 = 1'

/*line 9  : case-3 */ String  s3 = '10'
/*line 10 : case-3 */ int     n3 = s3 //Throwing Cast Exception
/*line 11 : case-3 */ println n3

Case-1

Line 3 prints `49`. It is ok as `char` is assgined to integer in line 2

Case-2
Line 7 prints  `n21` eventhough String is assgined in line 5... Is it right?

Line 6 : `n22` is assigned 1 as I have written `s2 as int`. This is ok

Case-3
Line 10 : Throwing GroovyCastException. This is ok.

The difference between Line-5 and Line-10 is the difference in String length. Both are Strings. The former is of length 1 and the latter is of length 2.

So, String with length 1, if assigned to int variable, assigns the ascii value. String with more than 1 length throws GroovyCastException This looks some what different...

Is it the acceptable behavior
