Conditional statements within loops and Loops within conditions.

i) Java Conditional Statements

ii) Java Loop Statements
----------------------------------------------------
Usage of Conditional Statements

1) Execute a Block of statements when condition is true

2) Execute a block of statements when a compound condition is true

3) Execute a block of statements when condition is true otherwise execute another block of statements

4) Decide among several alternates (else if)

5) Execute a block of statements when more than one condition is true

6) Decide among several alternates (using switch statement)
---------------------------------------------------
Java Loop Statements

Four Loop structures in Java

1) for loop

2) while loop

3) do while loop

4) enhanced for loop
-----------------------------------
1) for loop

Description: It repeats a block of statements for a specified number of times.

2) while loop

Description: It repeats a block of statements while condition is true

3) do while loop

Description: It repeats a block of statements while condition is true

Note: It executes statements at least once irrespective of the condition

4) Enhance for loop

Description: It executes all elements in an Array
------------------------------------------------------

We can use,

a) Only Conditions

b) only Loops

c) Condition/s within Loop/s

d) Loop/s within Condition/s
