Java 番石榴|短裤.包含()方法，带示例
原文:https://www . geesforgeks . org/Java-guava-shots-contains-method-with-examples/
短裤. contains() 是番石榴库中短裤类的一种方法，用于检查值目标是否作为数组中的元素出现。这些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。
语法:
public static boolean contains(short[] array,
short target)
参数:该方法取两个强制参数:
- Array: is an array of short values to search for. It may also be empty.
- Target: is the original short value to be searched in the array.
返回值:该方法返回一个布尔值，说明数组中是否存在目标值。如果目标存在，则返回真。
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
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
