2. Java 8 Read File + Stream + Extra. This example shows you how to use Stream to filter content, convert the entire content to upper case and return it as a List. gsutil uses HTTP Range GET requests to perform "sliced" downloads in parallel when downloading large objects from Cloud Storage. This means that disk space for the temporary download destination file will be pre-allocated and byte ranges (slices) within the file will be downloaded in parallel. Downloads: Java SE 7; Sample Code (Zip) Multicore processors are now widespread across server, desktop, and laptop hardware. They are also making their way into smaller devices, such as smartphones and tablets. They open new possibilities for concurrent programming because the threads of a process can be executed on several cores in parallel. Java has built-in support for concurrent programming by running multiple threads concurrently within a single program. A thread, also called a lightweight process, is a single sequential flow of programming operations, with a definite beginning and an end. During the lifetime of the thread, there is only a single point of execution. Java Multithreading and Concurrency Best Practices Sole purpose of using concurrency is to produce scalable and faster program. But always remember, speed comes after correctness. Your Java program must follow its invariant in all conditions, which it would, if executed in sequential manner. A client module connects to a server then a file is sent to the client. This example is very simple with no authentication and hard-coded filename!

Simple java application to download files from internet. It is similar to Internet Download Manager (IDM).

CSV Parser to read CSV files in Java Apache Commons CSV reads and writes files in variations of the Comma Separated Value (CSV) format. How to parse big JSON file using Jackson Streaming API? In this quick tutorial, we'll discuss how to zip a file into an archive and how to unzip the archive – all using core libraries provided by Java. These core libraries are part of the java.util.zip package – where we can find all zipping and unzipping related utilities.

In this Video I am going to give an Introduction to Java Threads. I will discuss, What is a Thread in Java. Then I will provide the Java Threads Overview. Threads is an Individual and separate a CPU. Multi threading extends the idea of multitasking into applications where you can subdivide specific operations within a single application into individual threads. Each of the threads can run in parallel. The OS divides processing time not only among different applications, but also among each thread within an application. Java has built-in support for concurrent programming by running multiple threads concurrently within a single program. A thread, also called a lightweight process, is a single sequential flow of programming operations, with a definite beginning and an end. During the lifetime of the thread, there is only a single point of execution.
