Java Guava | Shorts.indexOf(short[] array, short target) method with Examples

Shorts.indexOf(short[] array, short target) method of Guava’s Shorts Class accepts two parameters array and target. If the target exists within the array, the method returns the position of its first occurrence. If the target does not exist within the array, the method returns -1.

Syntax:

public static int indexOf(short[] array, short target)

Parameters: The method accepts two parameters:

array: which is the integer array in which the target array is to checked for index.
target: which is the value to be searched for as an element in the specified array.

Return Value: The method returns an integer value as follows:

It returns the position of first occurrence of the target if the target exists in the array.
Else it returns -1 if the target does not exist in the array.

Exceptions: The method does not throw any exception.

Below examples illustrate the implementation of above method:

Example 1:

// Java code to show implementation of 
// Guava's Shorts.indexOf(short[] array, 
// short target) method 
  
import com.google.common.primitives.Shorts; 
import java.util.Arrays; 
  
class GFG { 
  
    // Driver's code 
    public static void main(String[] args) 
    { 
  
        // Creating an short array 
        short[] arr = { 1, 2, 3, 4, 3, 5 }; 
  
        short target = 3; 
  
        System.out.println("Array: "
                           + Arrays.toString(arr)); 
  
        System.out.println("Target: " + target); 
  
        // Using Shorts.indexOf(short[] array, short target) 
        // method to get the position of the first 
        // occurrence of the specified target within array, 
        // or -1 if there is no such occurrence. 
        int index = Shorts.indexOf(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:

Array: [1, 2, 3, 4, 3, 5]
Target: 3
Target is present at index 2

Example 2:

// Java code to show implementation of 
// Guava's Shorts.indexOf(short[] array, 
// short target) method 
  
import com.google.common.primitives.Shorts; 
import java.util.Arrays; 
  
class GFG { 
  
    // Driver's code 
    public static void main(String[] args) 
    { 
  
        // Creating an short array 
        short[] arr = { 3, 5, 7, 11, 13 }; 
  
        short target = 23; 
  
        System.out.println("Array: "
                           + Arrays.toString(arr)); 
  
        System.out.println("Target: " + target); 
  
        // Using Shorts.indexOf(short[] array, short target) 
        // method to get the start position of the first 
        // occurrence of the specified target within array, 
        // or -1 if there is no such occurrence. 
        int index = Shorts.indexOf(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:

Array: [3, 5, 7, 11, 13]
Target: 23
Target is not present in the array
