How to make sure a String matches a Java class name -

using reflection , class.forname(string s) method, there way determine if string matches proper case of class?

example:

class: testreflection.java string s: testreflection  try{        class.forname(s) }     catch(classnotfoundexception e){     system.out.println("can't find class: " + s); } 

this misses classnotfoundexception , throws exception: exception in thread "main" java.lang.noclassdeffounderror: testreflection (wrong name: testreflection)

error log:

exception in thread "main" java.lang.noclassdeffounderror: reflection (wrong name:  testreflection) @ java.lang.classloader.defineclass1(native method) @ java.lang.classloader.defineclass(unknown source) @ java.security.secureclassloader.defineclass(unknown source) @ java.net.urlclassloader.defineclass(unknown source) @ java.net.urlclassloader.access$100(unknown source) @ java.net.urlclassloader$1.run(unknown source) @ java.net.urlclassloader$1.run(unknown source) @ java.security.accesscontroller.doprivileged(native method) @ java.net.urlclassloader.findclass(unknown source) @ java.lang.classloader.loadclass(unknown source) @ sun.misc.launcher$appclassloader.loadclass(unknown source) @ java.lang.classloader.loadclass(unknown source) @ java.lang.class.forname0(native method) @ java.lang.class.forname(unknown source) @ reflection.findclass(testreflection.java:50) @ reflection.main(testreflection.java:75) 

update: changed exception catch throwable.

i solved problem changing exception type catching classnotfoundexception throwable.
