Date of Performance: 16/02/2022
Subject Name: INTERNETPROGRAMMINGLAB Subject Code:20CAP-255
1. Aim/Overview of thepractical:
WriteaJavaprogramthatpromptstheuserforanintegerandthenprintsoutallprime numbers up to
thatinteger.
2. Task to bedone:
 Create a java class with suitablename.
 Enter aninteger.
 Run for loop from 2-n(n=integer).
 Check whether the no is Prime ornot.
3. Algorithm/Flowchart:
 Start ofProgram
 Take two integer n andp.
 Take n as userinput.
 Use for loops to check all the Prime number between2-n.
 If n is Prime printn.
 If n is not prime,skip.
 End of Program

2. 4. Code forexperiment/practical:
import java.util.Scanner;
class PrimeNumbersNew
{
publicstaticvoid main(String[] args)
{
int n;
int p;
Scanner s=new Scanner(System.in);
System.out.println("Enter a number: ");
n=s.nextInt();
for(int i=2;i<n;i++)
{
p=0;
for(int j=2;j<i;j++)
{
if(i%j==0)
p=1;
}
if(p==0)
System.out.println(i);
}
}
}
5. Result/Output/WritingSummary:

3. Learning outcomes (What I have learnt):
1. I learned how to provide user input injava.
2. I learned about java scannerclass.
3. Learned how to conditionalStatement.
4. Learned to use the concept ofloops.
