3. for(int i=2 ; i< n/2 ; i++) { res=n%i; if( res== 0) { flag = false; break; } if( flag) System.out.println(“Prime Number”); else System.out.println(“Not Prime Number”); }

4. WAP to display an Fibonacci series Import java.util.*; Class Fibo { public static void main(string args[]) { int prev,next,sum,n; prev=next=1;

5. for( n=1; n<= 10 ; n++) { System.out.println (prev); sum=prev + next; prev=next; next =sum; }
