Java Read TXT file

Today online random stroll around, somewhere to see the operation of the document, the description is good, deepened the understanding of the operation of the document, in this share to everyone. Hope to have something to gain.

Java reads the contents of the TXT file.

Can be understood as follows:

1. First get a file handle. File File = new file (); Files are file handles, which act as connections. Like, the two people have a telephone network, and then you can start to call.

2. Use this line to read the information of party A: new FileInputStream (file) reads this information into memory. Then party B will need to interpret what he understands.

3. Since you have used FileInputStream (). Then the corresponding need to use InputStreamReader () This method to interpret the memory just loaded in the data

4. Interpret the output after completion. It is natural to convert the data that can be recognized by IO. You can now call the ReadLine () method of BufferedReader () to read each row of data in the TXT file.
