The following Java application code-snippets compare execution time in seconds for various methods of reading a local text file into a Java String object.

       System:    Win95 Dell GxPro 200 MHz  64 Mb RAM
       JVM   :    jview.exe 5.00.3309     java.exe  1.3.0-C
       File  :    2.1 Mb text file

Code Description	bytecode	jview.exe (sec)	java.exe (sec)
Read into byte-buffer & convert to string	ReadIntoStr4.class	0.6	1.1
Read into byte-buffer & ByteArrayOutputStream	ReadIntoStr2.class	1.0	1.7
BufferedReader line at a time	ReadIntoStr3.class	1.7	2.1
Read single byte at a time	ReadIntoStr1.class	62	77
