how to convert the string to integer in java if the string is like

there is space in the beginning of the string. i tried
Integer.parseTnt(str) method. But java shows
NumberFormatException. Help me how to do?

I wanted to make my own encryption algorithm and decryption
algorithm , encryption algorithm works fine and converts ascii value
of the characters into alternate hexadecimal and octal
representations. But when I tried decryption, problem occured as it
return int('0671') = 671, as 0671 is string type in the following
code. Is there a method to convert "ox56" into integer form??????


NOTE: Following string is alternate octal and hexa of
ascii value of char.

/>///////////////DECRYPTION/////// />l="01630x7401620x6901560x67"
f=len(l)
k=0
d=0 />x=[]
for i in range(0,f,4):
g=l[i:i+4]
print g

Im my index index controller I have
@usergeo =
Geocoder.search("83.215.14.101")


result is:

/>Geocoder::Result::Freegeoip:0x007ff3ced35eb8 @data={ />"city"=>"Salzburg",
"region_code"=>"05", />"region_name"=>"Salzburg",
"metrocode"=>"", />"zipcode"=>"",
"longitude"=>"13.0333", />"latitude"=>"47.8",
"country_code"=>"AT", />"ip"=>"83.215.14.101",
"country_name"=>"Austria"},

@cache_hit=nil>]

.class means it is an
array!


In the view I try this one:


<%=
@usergeo["city"

I need to convert minutes (defined as Integer) into
the following String format "hh:mm" assuming that the
startTime is "00:00". The below-given code is what I have
so far, but it does not work properly. Also it does not take into
account that the newTime should be shifted in accordance
to startTime. Is there any other solution?

/>String startTime = "00:00";
int minutes = 120; />double time = minutes/60;
String timeS =
Double.toString(time);
String[] hourMin = timeS.split("."); />String h = hourMin[0];
String m = hourMin[1];
String
newTime = "";
newTime.concat(h+":"+m);<

Here's what I've done:


while (sc.hasNext()) { /> String sLine = sc.nextLine();

sLine.replaceAll("s", "");
String[] scanned =
sLine.split("");

My input is going to be
something like this:


IF (2 -2 +) (3 2 *) (-1 4 +) (5 3
*)

What this means is irrelevant, but what the
scanner does is store it in a string "as is", first of all. Then I
use the replaceAll function to remove all whitespace. I am then left
with:


IF(2-2+)(32*)(-14+)(53*)

I
then interpret this code using java and perform the calc
