Java Program Example

class PrimeNumber{
public static void main(String...s){
int n=8960, temp=0,m=n/2;
for(int i=2;i<m;i++){
if(n%i==0){
temp=1;
break;
}
else{
temp=0;
}
}
if(temp==1){
System.out.print("Not prime");
}
else{
System.out.print("prime no");
}
}
}

//user define java program to print array
package arrayexample;
import java.util.Scanner;
public class ArrayUser 
{
    static int n;
    public static void main(String[] args) {
    Scanner uk = new Scanner(System.in);
    System.out.println("Enter the number of element");
    n = uk.nextInt();
    int x[] = new int[n];	

    
    System.out.println("Enter "+ n +" numbers");
    for(int l=0;l<x.length;l++){
        x[l]= uk.nextInt();
    }
    
    System.out.println("OuTput:");
    System.out.println("Entered numbers are :");
    for(int l=0;l<x.length;l++){
        System.out.println(x[l]);
    }
}
}

Enter the number of element
4
Enter 4 numbers
12
38
07
89
OuTput:
Entered numbers are :
12
38
7
89
