Mell What is the difference between if and while loop in Java?
An if statement checks if an expression is true or false, and then runs the code inside the statement only if it is true. The code inside the loop is only run once… A while statement is a loop. Basically, it continues to execute the code in the while statement for however long the expression is true.
What is the difference between if statement and for loop with example?
Loop: Loop is a way to execute a statement or set of statement more than once. If-else: It select the statement on the basis of some conditions. if the condition is true then the body of if will be executed if the condition is false than the body of else will be executed.

What does the term DO WHILE LOOP mean?
In most computer programming languages, a do while loop is a control flow statement that executes a block of code at least once, and then either repeatedly executes the block, or stops executing it, depending on a given boolean condition at the end of the block. The do while construct consists of a process symbol and a condition.
What is an example of while loop?
A while loop is a control flow structure which repeatedly executes a block of code indefinite no. of times until the given condition becomes false. For example, say, you want to count the occurrence of odd numbers in a range. Some technical references call it a pre-test loop as it checks the condition before every iteration.
