java 数组的运用

public class array {

     /**

      * @param args

      */

     public static void main(String[] args) {

           // TODO Auto-generated method stub

           int a[]=new int[30];

              a[0]=1;

             a[1]=2;

           for(int i=2;i<a.length;i++ ){

              a[i]=a[i-1]+a[i-2];

              System. out.println("a[" +i+"]=" +a[i]);

          }

     }

}

结果
