BufferedReader object to variable br. A buffered reader provides for efficient

reading of characters, arrays, and lines.

isr = java.io.InputStreamReader(is)

br = java.io.BufferedReader(isr)

4. Read and Display Lines of Text

The final statement reads and displays the first 10 lines of text from the site.

Within a MATLAB

for statement that iterates 10 times, the BufferedReader

method

readLine reads a line of text (terminated by a return and/or line feed

character) from the site. To display the output in MATLAB, assign it to

variable

s, without terminating the statement with a semicolon.

for k = 1:10

s = readLine(br)

end
