Guava Shorts类
Shorts是原始类型short的一个实用类。它提供了与短基元有关的静态实用方法,这些方法在Short或Arrays中都没有找到。
声明 :
@GwtCompatible(emulated=true)
public final class Shorts
extends Object
下表显示了Guava Shorts Class的字段总结。
Guava Shorts Class提供的一些方法有: 异常情况。
- checkedCast : 如果值大于Short.MAX_VALUE或小于Short.MIN_VALUE,则出现IllegalArgumentException。
- min : 如果数组为空,则出现IllegalArgumentException。
- max : 如果数组为空,则出现IllegalArgumentException。
- fromByteArray : 如果字节数少于2个元素,会出现IllegalArgumentException。
- ensureCapacity : 如果minLength或padding为负数,则出现IllegalArgumentException。
- toArray : 如果集合或其任何元素为空,则出现NullPointerException。
下表显示了Guava Shorts Class提供的一些其他方法:下面给出的一些例子显示了Guava Shorts Class方法的实现:例子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<Short> myList = Shorts.asList(arr);
// Displaying the elements
System.out.println(myList);
}
}
输出:
[3, 4, 5, 6, 7]
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
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]
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
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
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
