Am trying to remove the spaces from the java string leaving the special characters,...
existing: "[Cars]/Info/{ 123} /{4533449 } ";
expected: "[Cars]/Info/{123}/{4533449}";
Any help would be really appreciated..
You should use .replace(toReplace, replaceWith) like so:
st.replaceAll("\\s+","")
Where st is "[Cars]/Info/{ 123} /{4533449 } "
This:
String st = "[Cars]/Info/{ 123} /{4533449 } ";
System.out.println(st.replaceAll("\\s+",""));
Produces this:
[Cars]/Info/{123}/{4533449}
If you want to remove the spaces for the specific variable, use
st = st.replaceAll("\\s+","")

I have a String value "\u0004"
I need to convert it to character '\u0004'
I need to store this character back to the string.
How can this be done?
Maybe this is answer you want
// string value that has "\" in front
String s = "\\u0004";
// substring to leave "\u" out
char c = (char)Integer.parseInt(s.substring(2));

String txt = "d89%l++5r19o7W *o=1645le9H"
System.out.println(t.replace(/\\d{0,}/g,''));
Because i'm bored...
String txt = "d89%l++5r19o7W *o=1645le9H";
txt = txt.replaceAll("\\d", "")
System.out.println(txt);
This will all numerical charactors from string
System.out.println(string.replaceAll("\\d",""));

I have a string that contains String q = "What's the value of √32 and √83?";, my problem is replacing √num with sqrt(32) and sqrt(83).
That means my string should output : -
What's the value of sqrt(32) and sqrt(83)
is it possible?
Use a regex replacement on the pattern √(\d+)\b, and replace with sqrt(...):
String q = "What's the value of √32 and √83?";
String output = q.replaceAll("√(\\d+)\\b", "sqrt($1)");
System.out.println(output);
This prints:
What's the value of sqrt(32) and sqrt(83)?

What I have:
String result = "<>hello<!><>Soumik<!><>Having a wonderful day?<!>";
What I need:
resultStrings = ["hello", "Soumik", "Having a wonderful day?"];
This regex should do the trick:
<[^>]*>([^<]+)<
Find all matches, and extract capturing group 1 from each.
Regex demo
How about that:
result = result.replace("<", "");
result = result.replace(">","";
resultStrings = result.split("!");
It's really simple.
I don't know other conditions so it may not be useful. Please add conditions so I can respond to it.

I have this number
6430134080234080234080200000000
and i want it in this form :
643,01,340802,340802,340802,00000000
My aim is to insert it to a database.
First off, you obviously don't have a number, but a string.
String s = "6430134080234080234080200000000";
You can format it like so:
String formatted = s.substring(0,3) + "," + s.substring(3,5) + "," ...
Note that this only works if the input string is of the same length.
