java - Difference between apostrophe and backslash+apostrophe -

-

i don't understand difference between "'" , "\'". is,

public class test {     public static void main(string[] args) {          system.out.println("hello, i'm best!");         system.out.println("hello, i\'m best!");       } }

gives same result:

hello, i'm best! hello, i'm best!

is feature of language? or may there more complicated description? there same result on android?

for string literals, there no difference between ' , \'. character literals, in java enclosed ' characters, escape necessary.

'''   // not legal character literal ' '\''  // escaped character literal '

according jls, section 3.10.6, java escapes string , character literals, can use them in both cases. quoting jls link:

the character , string escape sequences allow representation of nongraphic characters single quote, double quote, , backslash characters in character literals (§3.10.4) , string literals (§3.10.5).

as far know, android uses java, expect same hold android well.
