Input / Output in Java
● Programs read inputs from data sources (e.g.,
keyboard, file, network, memory buffer, or another
program) and write outputs to data sinks (e.g., display
console,file, network, memory buffer, or another
program).
● Java I/O (Input and Output) is used to process the input
and produce the output.
● Java uses the concept of stream to make I/O operation
fast.
The java.io package is used for java i/o (file handling).

Stream
• A stream can be defined as a sequence of data.
• A stream is an object that either delivers data to its
destination (screen, file, etc.) or that takes data from a
source (keyboard, file, etc.)

Stream cont..
• There are two kinds of Streams −
○ Input Stream − The Input Stream is used to read data
from a source.
○ Output Stream − The Output Stream is used for writing
data to a destination.

Continue…
● Java defines two types of streams. They are,
○ Byte Stream : It provides a convenient means
for handling input and output of byte.
○ Character Stream : It provides a convenient
means for handling input and output of
characters.

types of streams
• There are two types of streams :
• Byte Streams
• Character Streams

Byte stream
• Byte stream have been designed to provide functional
features for creating and manipulating streams and
files for reading and writing bytes.
• Bytes can transmit in only one direction.
• Byte streams create binary files.
• Binary files are faster to read and write because no
translation need take place.

Character stream
• Character streams can be used to read and
write 16-bit Unicode characters.
• Character streams create text files.
• Two kinds of character stream classes-

Standard Streams
Java provides the following three standard streams −
• Standard Input − This is used to feed the data to user's
program and usually a keyboard is used as standard input
stream and represented as System.in.
• Standard Output − This is used to output the data produced
by the user's program and usually a computer screen is used
for standard output stream and represented as System.out.
• Standard Error − This is used to output the error data
produced by the user's program and usually a computer
screen is used for standard error stream and represented
as System.err.

Threads in JAVAHaldia Institute of Technology

Threads allow multiple tasks to run concurrently within a single Java program. A thread represents a separate path of execution and threads can be used to improve performance. There are two main ways to create threads: by extending the Thread class or implementing the Runnable interface. Threads transition between different states like new, runnable, running, blocked, and terminated. Synchronization is needed to prevent race conditions when multiple threads access shared resources simultaneously. Deadlocks can occur when threads wait for each other in a circular manner.

In the fast-changing world of artificial intelligence, the industry is deploying more AI compute at the edge. But the growing diversity and data footprint of transformers and models such as large language models and large multimodal models puts a spotlight on memory performance and data storage capacity as key bottlenecks. Enabling the full potential of AI in industries such as manufacturing, automotive, robotics and transportation will require us to find efficient ways to deploy this new generation of complex models. In this presentation, Florentino explores how memory and storage are responding to this need and solving complex issues in the AI market. He examines the storage capacity and memory bandwidth requirements of edge AI use cases ranging from tiny devices with severe cost and power constraints to edge servers, and he explains how new memory technologies such as LPDDR5, LPCAMM2 and multi-port SSDs are helping system developers to meet these challenges.

The deployment of neural networks near sensors brings well-known advantages such as lower latency, privacy and reduced overall system cost—but also brings significant challenges that complicate development. These challenges can be addressed effectively by choosing the right solution and design methodology. The low-power FPGAs from Lattice are well poised to enable efficient edge implementation of models, while Lattice’s proven development methodology helps to mitigate the challenges and risks associated with edge model deployment. In this presentation, Hegade explains the importance of an integrated framework that tightly consolidates different aspects of edge AI development, including training, quantization of networks for edge deployment, integration with sensors and inferencing. He also illustrates how Lattice’s simplified tool flow helps to achieve the best trade-off between power, performance and efficiency using low-power FPGAs for edge deployment of various AI workloads.

1. Presentation On Input / Output in Java Presented By: Pratiksha Sharma B.C.A. 2nd Year Presented To: Apurva omer

2. Content:- • Input / Output in Java • Stream • types of streams • Byte stream • Character stream • Standard Streams

3. Input / Output in Java ● Programs read inputs from data sources (e.g., keyboard, file, network, memory buffer, or another program) and write outputs to data sinks (e.g., display console,file, network, memory buffer, or another program). ● Java I/O (Input and Output) is used to process the input and produce the output. ● Java uses the concept of stream to make I/O operation fast. The java.io package is used for java i/o (file handling).

4. Stream • A stream can be defined as a sequence of data. • A stream is an object that either delivers data to its destination (screen, file, etc.) or that takes data from a source (keyboard, file, etc.)

5. Stream cont.. • There are two kinds of Streams − ○ Input Stream − The Input Stream is used to read data from a source. ○ Output Stream − The Output Stream is used for writing data to a destination.

6. Continue… ● Java defines two types of streams. They are, ○ Byte Stream : It provides a convenient means for handling input and output of byte. ○ Character Stream : It provides a convenient means for handling input and output of characters.

7. types of streams • There are two types of streams : • Byte Streams • Character Streams

8. Byte stream • Byte stream have been designed to provide functional features for creating and manipulating streams and files for reading and writing bytes. • Bytes can transmit in only one direction. • Byte streams create binary files. • Binary files are faster to read and write because no translation need take place.

9. Character stream • Character streams can be used to read and write 16-bit Unicode characters. • Character streams create text files. • Two kinds of character stream classes-

10. Standard Streams Java provides the following three standard streams − • Standard Input − This is used to feed the data to user's program and usually a keyboard is used as standard input stream and represented as System.in. • Standard Output − This is used to output the data produced by the user's program and usually a computer screen is used for standard output stream and represented as System.out. • Standard Error − This is used to output the error data produced by the user's program and usually a computer screen is used for standard error stream and represented as System.err.
