1) Write a Java program that finds prime numbers between 1 to no , number accepted from Command line.

 

class Primeno

{

void prime(int n)

{

int d=2;

while(d<n)

{

if (n%d==0)

break;

else

d++;

}

if(d==n)

System.out.println(n+"is Prime");

}

public static void main(String args[])

{

Primeno p=new Primeno();

int no=Integer.parseInt(args[0]);

int i,j;

for(i=1;i<=no;i++)

{

p.prime(i);

}

}

}

 

Output:

D:\JavaPrograms\CmdPrograms>javac Primeno.java

D:\JavaPrograms\CmdPrograms>java Primeno 25

2is Prime

3is Prime

5is Prime

7is Prime

11is Prime
