P13 - Looping Statements (while and do-while) in Java | Core Java |

In this video, I have explained about "Looping Statements (while and do-while) in Java".

The while statement continually executes a block of statements while a particular condition is true. Its syntax can be expressed as:

while (expression) {
statement(s)
}

The while statement evaluates an expression, which must return a boolean value. If the expression evaluates to true, the while statement executes the statement(s) in the while block. The while statement continues testing the expression and executing its block until the expression evaluates to false.

You can implement an infinite loop using the while statement as follows:

while (true){
// your code goes here
}

The Java programming language also provides a do-while statement, which can be expressed as follows:

do {
statement(s)
} while (expression);

The difference between do-while and while is that do-while evaluates its expression at the bottom of the loop instead of the top. Therefore, the statements within the do block are always executed at least once.
