Java programming #6167
Description
What would you like to Propose?
//4.find the factorial program
package labtask3;
import java.util.Scanner;
public class Main {
public static void main(String[] args) {
Scanner input=new Scanner(System.in);
int num,fact=1;
System.out.print("enter any number= ");
//take as input user
num=input.nextInt();
for(int i=num;i>=1;i--) {
fact=fact*i;
}
System.out.println("Factorial is"+fact);
}
}
Issue details
//cheak if a prime number
package labtask3;
import java.util.Scanner;
public class Main {
public static void main(String[] args) {
Scanner input=new Scanner(System.in);
int num,count=0;
System.out.print("enter any positive integer numbet: ");
num=input.nextInt();
for(int i=2;i<num;i++) {
if(num%i==0) {
count++;
break;
}
}
if(count==0) {
System.out.println("Prime number");
}
else {
System.out.println("Not a prime number");
}
}
}
Additional Information
//7.fibonacci series
package labtask3;
import java.util.Scanner;
public class Main {
public static void main(String[] args) {
Scanner input=new Scanner(System.in);
int num;
int first=0,second=1,fibo;
System.out.print("enter number= ");
num=input.nextInt();
System.out.print(first+" "+second);
for(int i=3;i<=num;i++) {
fibo=first+second;
System.out.print(" "+fibo);
first=second;
second=fibo;
}
System.out.println();
}
