在java中删除数组元素的练习

public static void main(String[] args) {
    int[] m={1,2,3,4,5,6,7,8,9,10};
    System.out.println("请输入一个整数：");
    Scanner sc=new Scanner(System.in);
    int n=sc.nextInt();
    int index=Arrays.binarySearch(m,n);
    //System.out.println(index);
    if(index>=0){
        int a;
        a=m[index];
        for(int i=index;i<9;i++){m[i]=m[i+1];}
        m[9]=a;
        for(int e:m){
            System.out.print(e+"\t");
        }
    }else{
        System.out.println("数组中没有这个数！");
    }
}
