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.
