I am looking for a way or multiple ways (Always good to know many ways) how to convert Text (String) to HexaDecimal like this http://codebeautify.org/string-hex-converter
Any help would be appreciated.
I've been looking for hours around different places and I have so far found no code that could potentionally do this for me.
All the ways that this could be done is accepted, I love learning about coding.
String to Hex:
Integer.decode(hexString);
Hex to String:
Integer.toHexString(integer);

For some purpose, I want to convert the String to my Unicode to int or long or double. I just need a number. Can anyone tell me how can I do that?
If you want to get primitive values, use :
Integer.parseInt("12");
Long.parseLong("1024");
Double.parseDouble("1.52");
If you want to get objects corresponding to these values (Integer object, Long object, etc), use :
Integer.valueOf("12");
Long.valueOf("1024");
Double.valueOf("4.17");

I search but cannot find on the web.
Is there a function that can represent any integer into its String litteral representation ?
Example :
Integer i1 = new Integer(4);
Integer i2 = new Integer(30);
i1.callSomeFunction();
i2.callSomeFunction();
Output :
"Four"
"Thirty"
If you know another function which isn't in the Integer class, it's fine too.
There is no standard method to do this but take a look at this. There is an example for a number to words in the English language converter.

I have a equation in string format like "45+5*4-6" which I have to solve in Java.
Is there any way to solve equation which is in string format?
Check Beanshell
Something like this should work -
Interpreter ip = new Interpreter();
ip.eval("res = 45+5*4-6");
System.out.print(ip.get("res"));
