Back to Question 6

Answer 5

A batch file in Windows, or the equivalent in other operating systems, can be of some help in reducing the amount of typingrequired to compile and run a Java application from the command line.

Back to Question 5

Answer 4

False. Java uses huge class libraries, which few if any of us can memorize. Therefore, it is very difficult to program in Java without access to thedocumentation for the JDK.

As of November 2012, several different types of Java documentation are available online at (External Link) .

Back to Question 4

Prasenjit Reply
At high concentrations (>0.01 M), the relation between absorptivity coefficient and absorbance is no longer linear. This is due to the electrostatic interactions between the quantum dots in close proximity. If the concentration of the solution is high, another effect that is seen is the scattering of light from the large number of quantum dots. This assumption only works at low concentrations of the analyte. Presence of stray light.
