How to create a new instance of a class from a string?

[DannyBisby]

Hello all.
I am quite new to java and i would like to know how i can create a new instance of a class from a string where the class name is held.
I'm more from a php background and i know that i can do

$var = 'classname';
new $var();

to create a new instance of it

Currently in my java i have if statements to check the string name and then i do

return new ClassName().Execute().toString();

I'm looking for a more efficient way of doing this than having a if statement for every request that i have

Many thanks in advance

Look at the API docs for the java.lang.Class class.

To create an instance from a classname using the default constructor you can use:

Class myClass = Class.forName(myClassName);
obj = myClass.newInstance();

If you need to pass parameters into the constructor then use one of the getConstructor(s) methods to get the appropriate constructor and call its newInstance(...) method.
