An alternate approach to numerous "if" blocks??

Question

I have a part of code in my application where different objects are instantiated and some processing done based on one variable value. The present approach used numerous "if" statements. I would like to optimize this part of code.
Example of how my code looks now:
if( className.equals("A") {
Class1 c1 = new Class1();
c1.xxx();
c1.zzz();
if(className.equals("B") {
Class2 c2 = new Class2();
c2xxx();
c2zzz();
Will use of reflections in java be a wise choice here?
Is the use of 30 if conditions better or is it better to replace this whole "if" blocks of code with reflection?
Or can any other approach be used here?
Any help will be appreciated!!
Thanks!

interface FactoryByName {
    public abstract boolean likes(final String name);
    public abstract Object create();
class First implements FactoryByName {
    public final boolean likes(final String name) {
        return name.startsWith("A");
    public final Object create() {
        return new First();
class Second implements FactoryByName {
    public final boolean likes(final String name) {
        return name.startsWith("B");
    public final Object create() {
        return new Second();
class Factory {
    private static final FactoryByName[] FACTORIES = {
        new First(), new Second()
    public static final Object createByName(final String name) {
        for (FactoryByName current : FACTORIES) {
            if (current.likes(name)) {
                return current.create();
        return null;
public class Foo {
    public static final void main(final String[] args) {
        Object created = Factory.createByName("A");
        System.out.println(created.getClass().getName());
