How can I create a java program that reads from the user a number and searches for that number in an array?

Question

This is the code which I've tried so far:

int num;
       int[] a={2, 3, 4,7, 9};
       System.out.println("enter a no");
       for(int i=0; i<a.length; i++){
           num= in.nextInt();
           if(num==a[i])

Answer 1

It is easy:

int num;
boolean find = false;
   int[] a={2, 3, 4,7, 9};
   System.out.println("enter a no");
   num= in.nextInt();
   for(int i=0; i<a.length; i++){

       if(num==a[i]){
          find = true; 
          break;
       }
   }
System.out.println("Find = " + find);
