Performing Binary Search on Java short Array Example
This java example shows how to perform binary search for an element of
java short array using Arrays class.
*/
import java.util.Arrays;
public class BinarySearchShortArrayExample {
public static void main(String[] args) {
//create short array
short shortArray[] = {1,2,4,5};
/*
To perform binary search on short array use
int binarySearch(short[] b, short value) of Arrays class. This method searches
the short array for specified short value using binary search algorithm.
Please note that the short array MUST BE SORTED before it can be searched
using binarySearch method.
This method returns the index of the value to be searched, if found in the
array.
Otherwise it returns (- (X) - 1)
where X is the index where the the search value would be inserted.
i.e. index of first element that is grater than the search value
or array.length, if all elements of an array are less than the
search value.
*/
//sort short array using Arrays.sort method
Arrays.sort(shortArray);
//value to search
short searchValue = 2;
//since 2 is present in short array, index of it would be returned
int intResult = Arrays.binarySearch(shortArray,searchValue);
System.out.println("Result of binary search of 2 is : " + intResult);
//lets search something which is not in short array !
searchValue = 3;
intResult = Arrays.binarySearch(shortArray,searchValue);
System.out.println("Result of binary search of 3 is : " + intResult);
}
}
/*
Output would be
Result of binary search of 2 is : 1
Result of binary search of 3 is : -3
