Strings

[Anju sethi]

Question: What is the output of following if the return value is
"the value 0 if the argument string is equal to this string;
a value less than 0 if this string is lexicographically less than the string argument;
and a value greater than 0 if this string is lexicographically greater than the
string argument" (Assuming written inside main)

String s5 = "AMIT";
String s6 = "amit";
System.out.println(s5.compareTo(s6));
System.out.println(s6.compareTo(s5));
System.out.println(s6.compareTo(s6));

Ans
a) -32
32
0
b) 32
32
0
c) 32
-32
0
d) 0
0

What output did it generate when you ran the code?

[Anju sethi]

I am unable to sun this code as i am in a cyber cafe right now .
and found this problem just now in one of the mock exams.

Here the answer is A)

because


s5.compareTo(s6)

It starts comparing from the left side each character..

Here the first character is different and the difference is -32

A is 65 and a is 97




s6.compareTo(s5)



Same as above ..but now it is 97-65 =32


s6.compareTo(s6)


Here all the characters in both the objects are same and so difference is not there ....So 0.


Hope you got it...
