Program:

            /* ............... START ............... */
                
import java.util.Arrays;

public class JavaBinarySearchOnIntArray {

	public static void main(String[] args) {

		int intArray[] = { 1, 2, 4, 5 };

		Arrays.sort(intArray);

		int searchValue = 2;

		int intResult = Arrays.binarySearch(intArray, searchValue);
		System.out.println("Result of binary search of 2 is : " + intResult);

		searchValue = 3;
		intResult = Arrays.binarySearch(intArray, searchValue);
		System.out.println("Result of binary search of 3 is : " + intResult);

	}
}
                /* ............... END ............... */
        

Output

Result of binary search of 2 is : 1
Result of binary search of 3 is : -3
