公共静态诠释binarysearch()！我不知道它的正确形式.

问题描述

package binarysearch;
import java.util.Scanner;
public class Main {


    public static void main(String[] args) {
        Scanner input = new Scanner(System.in);
       int []a = new int [8];
       int low=0;
       int high=7;

       for(int i=0 ; i<a.length ; i++)
       {
     System.out.printf("\r\nPlease enter a number :",a[i]);
     a[i] = input.nextInt();
       }

     System.out.printf("\r\nPlease enter an integer :");
        int key = input.nextInt();

  //   System.out.printf("\r\nIt is in place "(binarysearch(numbers , low  ,high ,key)");

     public Static int binarysearch(int[]numbers,int key,int low , int high){

        if(low>high)
        {
            return -1;
        }
        int mid = (low + high)/2 ;
        if(numbers [mid] == key){
            return mid;

                if(key < numbers[mid])
                {
                    return binarysearch(numbers , low , mid-1 , key);
                }     else{
                        return binarysearch(numbers , mid+1,high , key);
   System.out.printf("\r\nIt is in place "(binarysearch(numbers , low  ,high ,key)");
                }

        }
        }
    }

我将这段代码放在< pre></pre>之间.标签，以使其更具可读性和b)显示基本错误；
