Subscript and Superscript a String in Android
(15 answers)
Closed 8 years ago.
I am writing a simple android app and I would like to set the text of a button to be X^n but I want it to look the same way as it would if you would write it on a piece of paper( for example 2⁶).
I know there are several unicode characters that does it for a small group of numbers but I am looking for a generel function (or any other way) that takes two integers and output the first by the power of the second. For example:
int X=2;
int n=6;
function(X , n) ==> 2⁶
I know a similar question was asked here before but its answers were not sufficient because I want to use variables' values and not actual numbers;
Thanks!
You can use html's <sup> tags for that:
button.setText(Html.fromHtml("X<sup>n</sup>"));

How to implement infinity in Java?

I want to implement the dijkstra algorithm and have to set each note at the beginning to infinity.
I would like to know, if there is any function in Java which makes it easy.
Double.POSITIVE_INFINITY if you are using Double to store your data.
Also note that this is not a number, which is nice depending on what you want to do. Double supports this concept.

I do not understand what the difference between
int Hello ;
and
int hello ;
is .
Does it make a big difference if i use upper case Characters ?
That's because of Java Convention!
Actually, you can write a program like the way you're imagining but, you won't be following any pattern.......If you become a real programmer someday, you'll understand that patterns exist to make things better and easier.....

I'm having a list of Integer from 1 to 100. If I loop through the list, I wanted to make the output as,
"One"
"Two" .....
"Hundred"
Is there any direct method in Java to obtain the above output?
No such method or class has been provided by JDK.
You can use the code mentioned here or here for reference purpose.
switch case are used to meet that requirement: Here
is source code.
Answer of this question described here: How to convert number to words in java
Officially this is not possible or no standard library available by native Java.
Don't duplicate.
There is none in the official Java libraries. However, the International Components for Unicode project has a RuleBasedNumberFormat with those capabilities. It even has a SPELLOUT constant.

DecimalFormat variable group size

An example will best explain what I want - lets say, I have a number like this 34236536465.57. I want to format it this way: 34,23,65,36,465.57. Any JDK classes or third party libraries I can use for this other than doing it manually please? I have tried with java.text.DecimalFormat("#,##,###.##"), but the commas are coming after 3 digits only whereas I want the commas to come first after 3 digits and then after 2 digits onwards.
com.ibm.icu.text.DecimalFormat class of ICU4J library can exactly do the same thing. And we can use the same pattern "#,##,###.##" as it is used in java.text.DecimalFormat to format the way exactly I wanted.

How do you find a roman numeral equivalent of an integer
I need to write a JSP function that will efficiently convert an integer (from 1 - 3000) to a roman numeral.
Start simple. Work out how you would convert the numbers 1 - 9 into Roman. Code and test. When it is working correctly, extend it to handle numbers up to 99. Again code and test. When it is working correctly, extend it to handle numbers up to 999. Code, test and extend up to 3,000.
Google has quite a few links to both algorithms and code:
