Most programs are more complicated because the sequence of statements and the number of times each is executed can vary. We use the term control flow to refer to statement sequencing in a program. Most computations require different actions for different inputs.
First we initialize it with 2 the smallest possible divider. The variable maxDivider is the maximum possible divisor, which is equal to the square root of the number.
This way we reduce the number of loop iterations. For the result we use a Boolean variable called prime. Initially, its value is true. While passing through the loop, if it turns out that the number has a divisor, the value of prime will become false.
The condition of the while loop consists of two other sub-conditions which are related to the logical operator logical and. In order to execute the loop, these two sub-conditions must be true simultaneously. If at some point we find a divisor of the number num, the variable prime becomes false and the condition of the loop is no longer satisfied.
Enter a positive number: True Enter a positive number: False Operator "break" The break operator is used for prematurely exiting the loop, before it has completed its execution in a natural way. We will demonstrate exiting from loop with break with an example.
Calculating Factorial — Example In this example we will calculate the factorial of a number entered from the console.
The calculation is performed by using an infinite while loop and the operator break. The factorial of an integer n is a function that is calculated as a product of all integers less than or equal to n or equal to it.
It is written down as n!This is obtained by writing it as a sum and using the fact that the sum of the first n consecutive squares is n(n + 1)(2n + 1) / 6 and the sum of the first n positive ints is n(n + 1)/2.

Write a program to play rock-paper-scissors, you against the computer. Use the integers 0, 1, 2 to represent rock, paper, and scissors. The program should continue until one of the players wins a round.
This Blog Contains Many Programs written in Java that I have worked on, beginning from the Basic Simple Programs to Advanced Programs and then programs in j2EE will also be posted.
