Write a method called convertDouble

[xaviermalcolm]

Hi

I'm doin a few java questions for an assignment.

I have been asked to:

1) Write a method called convertDouble as follows:
public double convertDouble (String value) {
...
}

This method should convert its parameter (a string like "3.1415") to the corresponding value of type double. If the string supplied is not a valid number, it should return 0.0 as its result. Note that you can use the method Double.parseDouble() to do the hard work for you.

Insert your convertDouble method in the space below:

2) Modify your convertDouble method to ignore any extra characters at the end of the string, so that convertDouble("3.1415xxx") will produce the value 3.1415 as its result.

Insert your convertDouble method in the space below:



I really dont have a clue to do either one of em
Please can anyone help with the lines of codes, i'll b very grateful

And what have you done so far. The rules here require you to have done something first to get much help.
