A boolean is a value which can either be true or false. A boolean condition is mathematical equation where the result is a boolean (either true or false). Often used in programming.
A boolean condition consists of some varibles, and boolean operations that can be carried out using them. Here are some boolean operations. The sybols are those used in Java and C++.
> Greater Than. Returns true when the number before > is greater than the number after
< Less Than. The opposite of Greater than
== Equals. If the values are equal returns true
OR Returns true if the boolean before and/or the boolean after is true
&& AND Returns true only if the boolean before AND after the && are true
! NOT Inverts/NOT's a boolean. True becomes false. False becomes true
Most programming languages have booleans as a type of variable and if statements as control flow.
An if statement uses a boolean to decide whether or not something is run eg.
if(someBoolean){
// If some boolean is true this peice of code will be run
}
A an example of a boolean condition could use a less than or greater than symbol
if( someNumber > 9000 ) {
print( "The number... it's.... OVER 9000!!" );
}

What is the Main diff for while and do while loop?
The main diff b/w while and do while is that for do while first the statment are exected then the condition is checked if the condition is true then again execute the statment and so on. But in case of while first the condition is checked if it is true then the statment are executed and so on. But in java the result of the condition is boolean eg. while(x=20) is not the condition in java it does not give any boolean answer.
