How to read numbers from text file

[Sunshineserene]

Hi, I want to know to rows and columns of numbers from a text file.
I do not want to read it as a string, but one number (including numbers with decimal) by itself. I tried using FileInputStream and DataInputStream, but I'm not really good at it. I don't know how to not read it as a double, and not a string.

What might also work then in that case, is maybe just converting the string that you're getting to an int or what ever you want? As in:

myInt = Integer.parseInt(theStringThatYoureGetting);

Following Dean_Grobler's suggestion you may read each number as a string s, and then convert s into a decimal number in the type of double by the following line of code:

double d = Double.parseDouble(s);

or convert s into a decimal number in the type of float:

float f = Float.parseFloat(s);
