Java中遍历array

public class Test
{
    public static void main (String[] args)
    {
        String[] a = {"roll out", "rule out", "normalcy", "palaver", "satirical", "rut"};

        //下面提供两种遍历array的方法:
        //第一种方法:
         for (int i = 0; i < a.length; i++)
        {
            System.out.println(a[i]);
        }
        System.out.println(); //遍历后，换行

        //第二种方法:
        for (String item : a)
        {
            System.out.println(item);
        }
    }
}
