Unitwise JP impotant Questions

 Unit-5

1) collections program with 6-8 methods. (ArrayList/LinkedList/HashSet/TreeSet as code is same).

2) reading and writing console input and output

3) Reading the content of file and write it into another file(Copying file content)

(or)

1) operations of files – reading, writing and copying files.

Unit-3&4

1)Multi threading creating 2 threads n execute concurrently.

2)Life cycle of Thread

3)Synchronization of threads.

4)Inter thread Communication.

1) Exceptions ( Checked & unchecked Exceptions)

    a). Arithmetic, ArrayIndex, Null pointer exceptions

   b). Customized exceptions

2)Built in exceptions

3) Exception hierarchy

 

Unit-2

1) Inheritance exampleprogram/ Types

2) Dynamic Method Dispatch( if u prepare this, u can write same for Method Overriding/Runtie polymorphism)

3)  Abstract classes, Interfaces (each 1 example prepare)

4) A)Built in packages

B) User defined Package(Convertor program)

 

 

Unit-1

We can’t expect which question comes all are important

1)Oops principles(Abstraction, Encapsulation, Inheritance, Polymorphism, class, object)

2)Java features(11 buzz  words-simple, object oriented, distributed, robust,…...........,dynamic)-either they may give any 5.

3)JVM architecture

4)Control statements/ Operators / Array(Matrix multiplication)

5)Constructor overloading program,

6)methods overloading program

7)String methods program with 6-8 methods.

8) Arrays

 

Note: U may get question on this, super, final

  Unit-3 1)  Classify exceptions in Java into checked and unchecked exceptions and give examples for each. An exception is an abnormal condition that arises in a code at run time. In other words, an exception is a runtime error.     Checked exceptions: A checked exception is an exception that occurs at the compile time, these are also called as compile time exceptions. 1. ClassNotFoundException:  This exception is thrown when the JVM tries to load a class, which is not present in the classpath .    Class.forName("oracle.jdbc.driver.OracleDriver"); 2.IOException:  This exception is thrown when the input-output operation in a program fails  or is interrupted during the program’s execution. 3. FileNotFoundException : This exception is thrown when the program tries to access a file that does not exist or does not open. This error occurs mainly in file handling programs.   import java.io.*; class FilenotFoundDemo {   public static v...

Java Programming Syllabus

  1. Course Description Course Overview This course provides Object Oriented Programming concepts using Java. The course focuses on different aspect of core Java Environment suitable to write efficient, maintainable, and portable code. It also ignites Object Oriented thinking and explores with the evolution of Java and its basics. It provides strong foundation on Inheritance, Packages and Interfaces and also illustrates Exception Handling and Multithreaded mechanisms. It also provides Collection framework for manipulating data. This course also focuses on file handling using Java API. 2. Course Outcomes (COs) After the completion of the course, the student will be able to: A8608.1 Make use of various constructs to write a console application. A8608.2 Use principles of OOP to develop real time applications. A8608.3 Identify the need of exception handling to deal with runtime errors. A8608.4 Build applications for parallel processing using Multithreading. A8608.5 Choose Collection fr...

  JAVA 1.  Java Defination: Java is a programming language and a platform.  Java is a simple, object oriented, distributed, robust, secure, architectural neutral, portable, interpreted, high performance, multithreaded and dynamic programming language.  Platform: Any hardware or software environment in which a program runs is known as a platform. Since Java has its own runtime environment (JRE) and API, it is called platform.   Java is used in the following applications: 1.  Desktop Applications/  Standalone application/ window-based application   An application that we need to install on every machine is called Desktop Application. Ex: acrobat reader, media player, antivirus  etc. AWT and Swing are used in java for creating standalone applications.(J2SE) 2.  Web Applications An application that runs on the server side and creates dynamic page, is called web application. Eg: irctc.co.in, cleartrip.com  etc. servlet, jsp, struts, jsf ...
