Fibonacchi numbers:

public class fibo{

     public static void main(String []args){
        int f0=0,f1=1,f;
        System.out.println("First 10 fibonacci numbers are:\n");
        for  (int i=1; i<=10;i++)
        {
            f=f0+f1;
            System.out.print(" "+f+" ");
            f1=f0;
            f0=f;
        }
     }
}

Array:

public class array{

     public static void main(String []args){
         int mark[]={23,58,59,27,92,13,45};
         for(int i=0; i<6; i++)
         {
             System.out.println("Mark[" +i+"]="+mark[i]);
         }
     }
}
