Java Guava | Shorts.lastIndexOf() method with Examples
  • Last Updated : 31 Jan, 2019

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
