短裤类 |番石榴 |Java
Shorts是原始类型 short 的实用程序类。它提供了与短原语有关的静态实用方法,这些方法在短原语或数组中都没有。
宣言 :
@GwtCompatible(emulated=true)
public final class Shorts
extends Object
下表显示了番石榴短裤类的字段摘要:
Guava Shorts Class 提供的一些方法是:
例外:
- checkedCast : IllegalArgumentException如果值大于 Short.MAX_VALUE 或小于 Short.MIN_VALUE
- min : IllegalArgumentException如果数组为空。
- max : IllegalArgumentException如果数组为空。
- fromByteArray : IllegalArgumentException如果 bytes 的元素少于 2 个。
- ensureCapacity : IllegalArgumentException如果 minLength 或 padding 为负数。
- toArray : NullPointerException如果集合或其任何元素为空。

下面给出了一些示例,展示了 Guava Shorts 类方法的实现:
示例 1:
// Java code to show implementation
// of Guava Shorts.asList() method
import com.google.common.primitives.Shorts;
import java.util.*;
class GFG {
// Driver method
public static void main(String[] args)
{
short arr[] = { 3, 4, 5, 6, 7 };
// Using Shorts.asList() method which convert
// array of primitives to array of objects
List myList = Shorts.asList(arr);
// Displaying the elements
System.out.println(myList);
}
}
输出 :
[3, 4, 5, 6, 7]
示例 2:
// Java code to show implementation
// of Guava Shorts.indexOf() method
import com.google.common.primitives.Shorts;
import java.util.*;
class GFG {
// Driver method
public static void main(String[] args)
{
short[] arr = { 3, 4, 5, 6, 7 };
// Displaying the index for
// first occurrence of given target
System.out.println(Shorts.indexOf(arr, (short)5));
}
}
输出 :
2
示例 3:
// Java code to show implementation
// of Guava Shorts.concat() method
import com.google.common.primitives.Shorts;
import java.util.*;
class GFG {
// Driver method
public static void main(String[] args)
{
short[] arr1 = { 3, 4, 5 };
short[] arr2 = { 6, 7 };
// Using Shorts.concat() method which
// combines arrays from specified
// arrays into a single array
short[] arr = Shorts.concat(arr1, arr2);
// Displaying the elements
System.out.println(Arrays.toString(arr));
}
}
输出 :
[3, 4, 5, 6, 7]
示例 4:
// Java code to show implementation
// of Guava Shorts.contains() method
import com.google.common.primitives.Shorts;
class GFG {
// Driver method
public static void main(String[] args)
{
short[] arr = { 3, 4, 5, 6, 7 };
// Using Shorts.contains() method which
// checks if element is present in array
// or not
System.out.println(Shorts.contains(arr, (short)8));
System.out.println(Shorts.contains(arr, (short)7));
}
}
输出 :
false
true
示例 5:
// Java code to show implementation
// of Guava Shorts.min() method
import com.google.common.primitives.Shorts;
class GFG {
// Driver method
public static void main(String[] args)
{
short[] arr = { 3, 4, 5, 6, 7 };
// Using Shorts.min() method
System.out.println(Shorts.min(arr));
}
}
输出 :
3
示例 6:
// Java code to show implementation
// of Guava Shorts.max() method
import com.google.common.primitives.Shorts;
class GFG {
// Driver method
public static void main(String[] args)
{
short[] arr = { 3, 4, 5, 6, 7 };
// Using Shorts.max() method
System.out.println(Shorts.max(arr));
}
}
输出 :
7
