Java番石榴 | Shorts.contains() 方法和示例

Shorts.contains()是 Guava 库中 Shorts 类的一个方法，用于检查值目标是否作为元素存在于数组中的任何位置。目标值和数组都作为该方法的参数。它返回一个布尔值，说明目标值是否存在。

句法：

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

参数：此方法采用两个强制性参数：

• 数组：这是一个短值数组，其中要搜索的目标。它也可能是空的。
• target：这是必须在数组中搜索的原始短值。

返回值：此方法返回一个布尔值，说明目标值是否存在于数组中。如果目标存在，则返回True 。

下面的程序说明了上述方法的使用：

示例 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

示例 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
