command line arguments

[steve_rm]

Hello

I am trying to use command line arguments to enter some float variables.

But l am unsure whether the command line arguments will accept anything else other than a string.

My code for this:
[code]

//Create a pool object from the class SwimmingPool, parameters
//to the constructor

Swimming pool = new SwimmingPool(args[0],args[1],args[2],args[3]);

[\code]

when l compile l use this
javac pool 10.0 15.0 10.0 20.0

and get a error message.

public static void main(String[] args)
instead of this could have float instead of string.

If his does not work, is there a way to convert a string data type to a float data type, that would work for me.

Many thanks in advance

float temp = 0;
String parse = "123.456";
		
try 
{
    temp = Float.parseFloat(parse);
    System.out.println(temp);
}
catch (NumberFormatException nfe)
{
    System.out.println("Invalid number");
}

Hey you shouldn't use javac for running your classes (I'm sure you justed typed wrong, I'm telling you just in case)
