Java Write HTTP server download tool _java

This tool is simpler to use with another tool for file transfer, less nonsense, on code

This tool implements a file that downloads a specified number of rows from the HTTP server and does not cause the downloaded file contents to be garbled because of the encoding problem
Three tools have been fixed, the next time is to combine the three tools to transfer HTTP, FTP files to HDFs

Hadoop Tools
FTP Tools
