I want to convert GBP 29.15* to just 29.15.
Can anyone please help?
I have already tried parsing to integer/float, substring etc. but getting an error.
Try this:
float f = Float.valueOf("GBP 29.15*".replaceAll("[^\\d.]+|\\.(?!\\d)", ""));
It removes all non-number characters and then finds the float value.

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)?

Not sure if this will cover all corner cases, but this regex should work for your example:
String json = ...
json = json.replaceAll("[^{}\\[\\]:,]+", "\"$0\"");

What is the best way to parse a String value that looks like this id#1 ...id#398, so I can get de number after the id# String in JAVA.
If id# is a fixed prefix in every ID, I would have used
stringValue.split("id#")[0]

I've got many resources with names based on a pattern:
R.drawable.small_house_red
R.drawable.small_house_blue
R.drawable.big_house_black
R.drawable.small_tree_red
I've got 3 strings: size, type, color. I can put all required resources to map, and get them by concated string but is it possible to get them without manually entering all combinations to the map?
You can use this
int id = context.getResources().getIdentifier("imageNameAsString", "drawable", context.getPackageName());
