###### One Dimensional Array - Question 4

In this question, we will see how to input 10 numbers in a one dimensional integer array and print only the prime numbers from it in Java programming. To know more about one dimensional array click on the one dimensional array lesson.

**Q4)** Write a program in Java to input 10 numbers in a one dimensional integer array and print only the prime numbers from it.

A prime number is a number which is divisible by 1 and itself. Example: 13, 17, 19, etc.

#### Program

```
import java.util.Scanner;
public class Q4
{
public static void main(String args[])
{
int a[]=new int[10], i,j,c=0;
Scanner sc=new Scanner(System.in);
System.out.println("Enter 10 numbers");
for(i=0; i<10; i++)
{
a[i]=sc.nextInt();
}
System.out.println("\nPrime Numbers");
for(i=0; i<10; i++)
{
c=0;
for(j=1; j<=a[i]; j++)
{
if(a[i]%j==0)
{
c++;
}
}
if(c==2)
{
System.out.print(a[i]+" ");
}
}
}
}
```

#### Output

Enter 10 numbers 5 12 18 23 17 45 93 62 7 54 Prime Numbers 5 23 17 7
