Converting Integers / Float/ Double etc to strings

[Tim Dee]

I know how to convert a string to Float / int etc

fec = Float.parseFloat(args[1])

But how do I go in the other direction and convert a integer to a string?

Cheers

There are a number of ways to do it. I like to use the bunch of static "valueOf" methods in the String class:

int anInt = 3;
String intAsString = String.valueOf(anInt);

There are a number of different ways to do it.

Check out the API documentation of class java.text.DecimalFormat and of the method String.format(...). With those, you can specify exactly with which format you want the numbers to be converted to strings.

You can also use the static toString(...) methods of the wrapper classes, but those won't allow you to specify the format.

String s1 = Integer.toString(123);
String s2 = Double.toString(3.14159265);

Or even a trick like this, which will automatically call the toString(...) of the wrapper classes behind the scenes.

String s1 = "" + 123;
String s2 = "" + 3.14159265;
