The lastIndexOf() method of Shorts Class in Guava library is used to find the last index of the given short value in a short array. This short value to be searched and the short array in which it is to be searched, both are passed as a parameter to this method. It returns an integer value which is the last index of the specified short value. If the value is not found, it returns -1.
Syntax:
public static int lastIndexOf(short[] array,
short target)
Parameters: This method accepts two mandatory parameters:
- array: which is the array of short values in which the short value is to searched.
- target: which is short value to be searched for last index in the short array.
Return Value: This method returns an integer value which is the last index of the specified short value. If the value is not found, it returns -1.
Below programs illustrates this method:
Example 1:
// Java code to show implementation of// Guava's Shorts.lastIndexOf() method  import com.google.common.primitives.Shorts;import java.util.Arrays;  class GFG {      // Driver's code    public static void main(String[] args)    {          // Creating a short array        short[] arr = { 1, 2, 3, 4, 3, 5, 3, 4 };          short target = 3;          // Using Shorts.lastIndexOf() method        // to get the index of last appearance        // of a given element in array        // and return -1 if element is        // not found in the array        int index            = Shorts.lastIndexOf(arr, target);          if (index != -1) {            System.out.println("Target is present"                               + " at index "                               + index);        }        else {            System.out.println("Target is not present"                               + " in the array");        }    }} |
Output:
Target is present at index 6
Example 2:
// Java code to show implementation of// Guava's Shorts.lastIndexOf() method  import com.google.common.primitives.Shorts;import java.util.Arrays;  class GFG {      // Driver's code    public static void main(String[] args)    {        // Creating a short array        short[] arr = { 3, 5, 7, 11, 13 };          short target = 17;          // Using Shorts.lastIndexOf() method        // to get the index of last appearance        // of a given element in array        // and return -1 if element is        // not found in the array        int index            = Shorts.lastIndexOf(arr, target);          if (index != -1) {            System.out.println("Target is present"                               + " at index "                               + index);        }        else {            System.out.println("Target is not present"                               + " in the array");        }    }} |
Output:
Target is not present in the array
