Unit 14 : Input/output:

November 25, 2018BIM Notes

Java I/O A stream is continuous group of data or a channel through which data flows from one point to another point. Java implements streams within class hierarchies defined in the java.io package. Byte streams provide a convenient means for handling input and output of bytes. Byte streams are used, for example, […]

Unit 13 : String handling

November 25, 2018BIM Notes

String A string is a set of one or more characters enclosed in double quotes or simply a string is an array of characters. Strings, which are widely used in Java programming, are a sequence of characters. In the Java programming language, strings are objects. The Java platform provides the String class to create […]

Unit 11 : Multithreaded programming

November 25, 2018BIM Notes

A multithreaded program contains two or more parts that can run concurrently. Each part of such a program is called a thread, and each thread defines a separate path of execution. Thus, multithreading is a specialized form of multitasking. There are two distinct types of multitasking: process-based and thread-based. A process-based multitasking is the feature […]

Unit 10 : Exception handling java programming

November 25, 2018BIM Notes

Exception Handling Error occurred in a program can be of two types: syntax error or logical error. An exception is an abnormal condition that arises in a code sequence at run time. In other words, an exception is a run-time error. A Java exception is an object that describes an exceptional (that is, […]

Unit 9 : Packages and Interface

November 25, 2018BIM Notes

Package and Interface Packages are containers for classes that are used to keep the class name space compartmentalized. For example, a package allows us to create a class named List, which you can store in your own package without concern that it will collide with some other class named List stored elsewhere. Packages are stored in a […]
