Java String 的实例(02)

1.初始化数组以及数组的拷贝

int[] a={1,2,3,4};
       //System.out.println(Arrays.toString(a));
       a=new int[]{1,2,3,4,5};
       int [] c=a;
       //c[4]=15;
       int[] d=Arrays.copyOf(a,a.length);
       for (int i : d) {
           System.out.println(i);
       }
       2.快速排序

int[] a={10,55,166,55,22};
