The steps to invoke a binary search algorithm in Java are as follows:<\/p>\n

    \n
  1. Create an array and make sure it is already sorted.<\/li>\n
  2. Call the binary search algorithm method, passing in the target value to be searched for and the array to be searched.<\/li>\n
  3. Implement the binary search algorithm in the method by passing in the target value and the array, and finally return the position of the target value in the array.<\/li>\n<\/ol>\n

    Here is an example code:<\/p>\n

    public<\/span> class<\/span> BinarySearch<\/span> {\r\n\r\n    public<\/span> static<\/span> int<\/span> binarySearch<\/span>(int<\/span>[] arr, int<\/span> target)<\/span> {\r\n        int<\/span> left<\/span> =<\/span> 0<\/span>;\r\n        int<\/span> right<\/span> =<\/span> arr.length - 1<\/span>;\r\n\r\n        while<\/span> (left <= right) {\r\n            int<\/span> mid<\/span> =<\/span> left + (right - left) \/ 2<\/span>;\r\n\r\n            if<\/span> (arr[mid] == target) {\r\n                return<\/span> mid;\r\n            } else<\/span> if<\/span> (arr[mid] < target) {\r\n                left = mid + 1<\/span>;\r\n            } else<\/span> {\r\n                right = mid - 1<\/span>;\r\n            }\r\n        }\r\n\r\n        return<\/span> -1<\/span>;\r\n    }\r\n\r\n    public<\/span> static<\/span> void<\/span> main<\/span>(String[] args)<\/span> {\r\n        int<\/span>[] arr = {1<\/span>, 3<\/span>, 5<\/span>, 7<\/span>, 9<\/span>, 11<\/span>, 13<\/span>};\r\n        int<\/span> target<\/span> =<\/span> 7<\/span>;\r\n\r\n        int<\/span> result<\/span> =<\/span> binarySearch(arr, target);\r\n\r\n        if<\/span> (result == -1<\/span>) {\r\n            System.out.println(\"\u76ee\u6807\u503c\u4e0d\u5b58\u5728\u6570\u7ec4\u4e2d\"<\/span>);\r\n        } else<\/span> {\r\n            System.out.println(\"\u76ee\u6807\u503c\u5728\u6570\u7ec4\u4e2d\u7684\u4f4d\u7f6e\u662f\uff1a\"<\/span> + result);\r\n        }\r\n    }\r\n}\r\n<\/code><\/pre>\n
    In the above example, we first define a binarySearch method to implement the binary search algorithm, then in the main method we create a sorted array called arr and a target value called target, and finally call the binarySearch method to find the position of the target value in the array.<\/p>\n","protected":false},"excerpt":{"rendered":"
