Introduction

The first step

The first step in learning to use a new programming language is usually to learn the foundation concepts such as variables, types, expressions,flow-of-control, etc. This module concentrates on flow-of-control .

Flow of control

What is flow of control?

Java supports several different kinds of statements designed to alter or control the logical flow of the program.

The ability to alter the logical flow of the program is often referred to as Flow of Control .

Statements that support flow of control

Figure 1 lists the statements supported by Java for controlling the logical flow of theprogram.

The while statement

We've seen the while statement in earlier modules. Several of the programs in earlier modules contained a while statement designed to control the logical flow of the program.

what are the products of Nano chemistry?
Maira Reply
There are lots of products of nano chemistry... Like nano coatings.....carbon fiber.. And lots of others..

what about nanotechnology for water purification
RAW Reply
please someone correct me if I'm wrong but I think one can use nanoparticles, specially silver nanoparticles for water treatment.
Damian
yes that's correct

Nasa has use it in the 60's, copper as water purification in the moon travel.

is there industrial application of fullrenes. What is the method to prepare fullrene on large scale.?
Rafiq
industrial application...? mmm I think on the medical side as drug carrier, but you should go deeper on your research, I may be wrong
