在Java长数组上执行二进制搜索

/*from nowjava - 时  代  Java*/


import java.util.Arrays;

 

public class Main {

  public static void main(String[] args) {

    long longArray[] = {1,2,4,5};

    Arrays.sort(longArray);

   

    long searchValue = 2;

   

    long intResult = Arrays.binarySearch(longArray,searchValue);

    System.out.println("Result of binary search of 2 is : " + intResult);

   

    searchValue = 3;

    intResult = Arrays.binarySearch(longArray,searchValue);

    System.out.println("Result of binary search of 3 is : " + intResult);
