or error.. I confused

daksha foundation  to  Everyone 9:57
why
can you give me the reason
did you know?
aswathy did you know the reason
amarjith?

Amarjith As  to  Everyone 10:00
Code is error i think

daksha foundation  to  Everyone 10:00
why
we have two values in the bracket

You  to  Everyone 10:01
int x = 10

Amarjith As  to  Everyone 10:02
value is will be answer

daksha foundation  to  Everyone 10:02
(10+"20")
then the first number 10 is the integer value

daksha foundation  to  Everyone 10:02
then the "20" is the string value

Sreelakshmi 10:08
ma'am why "20" come string value 20 is number?

daksha foundation  to  Everyone 10:03
+ operator is used to concatenate the two varibles
so in the java the integer will be automatically converted into string
then the java is used to print 1020
so the answer is 1020

daksha foundation  to  Everyone 10:04

You  to  Everyone 10:05
l understand ma'am

Aswathy Ammu  to  Everyone 10:05
