数组的遍历及反转

public static void main(String[] args) {
    int[] arrays={1,2,3,4,5};
    /*//遍历
    for (int i = 0; i < arrays.length; i++) {
        System.out.println(arrays.length);
    }*/


    int[] rev=rev(arrays);
    p(rev);
}
//反转数组
public static int[] rev(int[] arrays){
    int[]s =new int[arrays.length];
    //反转的操作
    for(int i=0,j=s.length-1;i<arrays.length;i++,j--){
    s[j]=arrays[i];
    }
    return s;
}
public static void p(int[] arrays){
    for (int i = 0; i < arrays.length; i++) {
        System.out.println(arrays[i]+"");
    }
}
