Guava – Shorts.contains()方法及实例

Guava – Shorts.contains()方法及实例

Shorts.contains()是Guava库中Shorts类的一个方法,用于检查目标值是否作为数组中的一个元素存在。目标值和数组都是这个方法的参数。它返回一个布尔值,说明目标值是否存在。

语法:

public static boolean contains(short[] array,
                               short target)

参数:该方法需要两个强制性参数。

  • array:这是一个短值数组,目标将在其中被搜索到。它也可以是空的。
  • target: 这是必须在数组中搜索的原始短值。

返回值: 该方法返回一个布尔值,说明目标值是否存在于数组中。如果目标值是存在的,它返回True。

下面的程序说明了上述方法的使用。

例子-1 :

// Java code to show implementation of
// Guava's Shorts.contains() 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 = { 5, 4, 3, 2, 1 };
  
        short target = 3;
  
        // Using Shorts.contains() method to search
        // for an element in the array. The method
        // returns true if element is found, else
        // returns false
        if (Shorts.contains(arr, target))
            System.out.println("Target is present in the array");
        else
            System.out.println("Target is not present in the array");
    }
}

输出:

Target is present in the array

例2 :

// Java code to show implementation of
// Guava's Shorts.contains() 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 = { 2, 4, 6, 8, 10 };
  
        short target = 7;
  
        // Using Shorts.contains() method to search
        // for an element in the array. The method
        // returns true if element is found, else
        // returns false
        if (Shorts.contains(arr, target))
            System.out.println("Target is present in the array");
        else
            System.out.println("Target is not present in the array");
    }
}

输出:

Target is not present in the array
