binarySearch method in JAVA

User_6R2K6

I couldn't use binarySearch method for manipulating Array. I received this error: "Cannot invoke binarySearch() on the array type int[] " . what should I do?

I don't know what you tried. At least following static method should work:

java.util.Arrays.binarySearch(array, searchValue)

Example from JShell:

jshell> int[] arr = {10, 12, 14, 16}
arr ==> int[4] { 10, 12, 14, 16 }

jshell> Arrays.binarySearch(arr, 12)
$2 ==> 1

jshell> Arrays.binarySearch(arr, 14)
$3 ==> 2
