java is case sensitive
--------------------------------------pls explain its an hurry

Answer 1

Yes, Java is  case sensitive.
 
 For Java , a capital and a small letter are two different things.
 For eg: it handles "a"  and "A" as two different values or constants

Answer 2

Java is case sensitive means it considers the upper case and lower case letters as different entity. You can't write "System" as "system". They are different.
