The exceptions thrown by the “readObject” method is as follows:
- “InvalidClassException”
- The “InvalidClassException” thrown when the serialization runtime detects one of the following issues with a class:
- The class contains unknown data types
- The class descriptor does not match with the serial version of the class when read from the stream.
- The class does not have an accessible no-argument constructor.
- The “InvalidClassException” thrown when the serialization runtime detects one of the following issues with a class:
- “IOException”
- An “IOException” is thrown when there is any input/ output file operation issues while application performing particular tasks accessing the files...

How to create method in groovy language.
Actually I created one but i am getting missonmethod exception. Please help me
Give me answer fast please.
Let's revisit chapter 5 example, but this time, no method can throw any exception out of the method and if an exception was detected then you will have to throw your own custom exception to let the user know what happened.
public class Chapter11Demo{ public static void main(java.lang.String[] args) {method1();}private static void method1(){ method2();}private static void method2(){ method3();}private static void method3(){ method4();}private static void method4(){ method5();}private static void method5(){ method6();}private static void method6(){ java.io.File in=new java.io.File("somefile.txt"); java.io.File out=new java.io.File("somefile2.txt"); java.util.Scanner inFile=new java.util.Scanner(in); java.io.FileWriter outFile=new java.io.FileWriter(out); }}

Make the class Comparable and write a compareTo method that compares Disks based on the size of the disk. Make sure your comparison accounts for the fact that some numbers are in GB and some are in TB. Write a method that will return true if the disk is the same size as the parms; parms are the size and measure("GB" or "TB"). Also write a method to create a Comparator which compares Disks based on the performance rating. -The client code should do the following: Write a function called build, which will open the disks.txt file, read in each disk and add it to the BST.
