Guava的Bytes類的Bytes.contains()方法接受兩個參數array和target。該方法用於檢查目標元素是否存在於數組中。
用法:
public static boolean contains(byte[] array, byte target)
參數:該方法接受兩個參數:
- array:字節值數組,可能為空。
- target:要檢查數組中是否存在原始字節值。
返回值:如果目標在數組中的任何位置作為元素存在,則該方法返回true;如果目標在數組中的任何位置都不存在,則返回false。
異常:該方法不會引發任何異常。
以下示例說明了上述方法的實現:
範例1:
// Java code to show implementation of
// Guava's Bytes.contains() method
import com.google.common.primitives.Bytes;
import java.util.Arrays;
class GFG {
// Driver's code
public static void main(String[] args)
{
// Creating a Byte array
byte[] arr = { 5, 4, 3, 2, 1 };
byte target = 3;
// Using Bytes.contains() method to search
// for an element in the array. The method
// returns true if element is found, else
// returns false
if (Bytes.contains(arr, target))
System.out.println("Target is present"
+ " in the array");
else
System.out.println("Target is not present"
+ " in the array");
}
}
輸出:
Target is present in the array
範例2:
// Java code to show implementation of
// Guava's Bytes.contains() method
import com.google.common.primitives.Bytes;
import java.util.Arrays;
class GFG {
// Driver's code
public static void main(String[] args)
{
// Creating a Byte array
byte[] arr = { 2, 4, 6, 8, 10 };
byte target = 7;
// Using Bytes.contains() method to search
// for an element in the array. The method
// returns true if element is found, else
// returns false
if (Bytes.contains(arr, target))
System.out.println("Target is present"
+ " in the array");
else
System.out.println("Target is not present"
+ " in the array");
}
}
輸出:
Target is not present in the array
