Prime Number Between Given Range in Java

Prime Number Between Given Range in Java Program. A prime number is a number bigger than one that has only two factors: itself and one. A prime number cannot be divided by another prime number without a remainder.

public class Main
{
public static void main(String[] args)
{
int lowest = 20, highest = 50;
while (lowest < highest)
{
boolean flag = false;
for(int i = 2; i <= lowest/2; ++i)
{
if(lowest % i == 0)
{
flag = true;
break;
}
}
if (!flag && lowest != 0 && lowest != 1)
System.out.print(lowest + " ");
++lowest;
}
}
}

 

Output:

23 29 31 37 41 43 47

Prime Number Between Given Range in Java

A prime number is a whole number bigger than one with just one and itself as factors. A factor is a full number that may be evenly split into another. 2, 3, 5, 7, 11 are the first few prime numbers. Composite numbers are those that have more than two components. The number one is neither composite nor prime. Using this method we can execute prime number between two intervals in java for developers.

Prime Number Between Given Range in Java and How it is Important

Primes are utilised in a variety of computer programs, including public-key cryptography, which relies on the difficulty of factoring huge integers into prime factors. Prime elements and prime ideals are abstract algebra objects that behave like prime numbers in a generalised sense. prime number between two intervals in java.

What is Pre Increment and Post Increment in Java

The term “pre-increment” refers to the incrementing of a variable before it is evaluated in an expression. The term “post-increment” refers to the incrementing of a variable after it has been evaluated for use in an expression. Incrementing operator plays the major role in this prime number between two intervals in java.

What is Flag Variable in Java

A flag variable is a source data variable that has been discovered as a mechanism to signal the clinical relevance of lab test or vital sign findings, or to indicate whether treatment-emergent adverse events have occurred. Frequently, the supplied value is for a research data supplemental qualifier variable. Flag variables are very useful for this kind of programs to develop a prime number between two intervals in java program for beginners.
