Answer / chaitu
Class File verification is used by Java Virtual Machine (JVM) before full startup of the JVM occurs in running bytecode of an application. This can be done in four Passes-
Pass-1:- Check byte code attributes, magic number, constant pool must not have any superficial data, and class file must not have extra bytes at end.
Pass-2:- Check every class behaviour and attribute and every class has valid names, classes, descriptor, and packages.
Pass-3:- Check code linking, attribute, and analysis data flow.
Pass-4:- Check where class loading occurs to finalize the class verification process.

write a program to input a natural number less than and display it in words.test your program on the sample data and some random data sample input= 29 sample output= Twenty nine sample input=17001 sample output= out of range sample input=119 sample output =one hundred and nineteen sample input=500 sample output=five hundred
Will J2ME applications run on J2SE?
