How to compress data in Java?
DeflaterOutputStream and InflaterInputStream classes are provided in Java to compress and decompress the file contents.
These classes provide useful methods that can be used for compressing the file content.
This class implements an output stream filter for compressing data in the “deflate” compression format..
Lossless compression techniques
Compression algorithms such as gzip, bzip2 and 7-zip can achieve compression ratios of 2:1 or higher, depending on the data.
Compression ratios of 2:1 to 3:1 are common for text files and other types of data with a high degree of redundancy..
Lossless compression techniques
To determine the compression ratio, divide the size of outputFile value by groupPages value.
For example, if the size of outputFile value is 40 000 bytes and the size of the group of pages is 200 000 bytes, then the compression ratio is 40000/200000 or 0.20 (5:1 compression)..
What is data compression and why we need it javatpoint?
What is Data Compression.
Data Compression is also referred to as bit-rate reduction or source coding.
This technique is used to reduce the size of large files.
The advantage of data compression is that it helps us save our disk space and time in the data transmission..

DC: Data Compression
DC is a digital signal process in which data to be transmitted is compressed to reduce the storage amount in bits.
In other words, you can say that data storage space is reduced than usual after applying DC..
