原文:https://www . geesforgeks . org/Java-guava-longs-contains-method-with-examples/
番石榴的朗斯等级的朗斯包含()方法用于检查数组中是否存在值，即目标。该目标值和数组被作为该方法的参数。此方法返回一个布尔值，该值表示目标值是否为
语法:
public static boolean contains(long[] array,
long target)
参数:该方法接受两个参数:
- array: is the value array for which the target value is to be searched.
- Target: is the long value to be checked for existence.
返回值:该方法返回 真 如果对于 I 的某个值，i th 索引处存在的值等于目标，否则返回 假 。
异常:方法不抛出任何异常。
例 1:
// Java code to show implementation of
// Guava's Longs.contains() method
import com.google.common.primitives.Longs;
import java.util.Arrays;
class GFG {
// Driver's code
public static void main(String[] args)
{
// Creating a long array
long[] arr = { 5L, 4L, 3L, 2L, 1L };
long target = 3L;
// Using Longs.contains() method to search
// for an element in the array. The method
// returns true if element is found, else
// returns false
if (Longs.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 Longs.contains() method
import com.google.common.primitives.Longs;
import java.util.Arrays;
class GFG {
// Driver's code
public static void main(String[] args)
{
// Creating a long array
long[] arr = { 2L, 4L, 6L, 8L, 10L };
long target = 7L;
// Using Longs.contains() method to search
// for an element in the array. The method
// returns true if element is found, else
// returns false
if (Longs.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
