Read the API documentation for the java.lang.String class.
Read every line of your text.
Apply one of String metods to each line to chack word matching.
The indexOf() method will be handy.

Hi,

Use the java.io.File API to open up the file, and then use the
java.io.BufferedReader API to read it line by line. For every line,
based on case sensitivity, you can either do a
line.toUpperCase().indexOf("computer".toUpperCase()) > 1 or
line.indexOf("computer") > 1.

No. You can't do that. Simply create a BufferedReader passing a
FileReader(yourfile) to its constructor.

Last I checked, this is how it works. Anything I missed?
