Guava - Shorts Class
Shorts is a utility class for primitive type short.
Class Declaration
Following is the declaration for com.google.common.primitives.Shorts class −
@GwtCompatible public final class Shorts extends Object
Fields
Sr.No | Field & Description |
---|---|
1 |
static int BYTES The number of bytes required to represent a primitive short value. |
2 |
static short MAX_POWER_OF_TWO The largest power of two that can be represented as a short. |
Methods
Sr.No | Method & Description |
---|---|
1 |
static List<Short> asList(short... backingArray) Returns a fixed-size list backed by the specified array, similar to Arrays.asList(Object[]). |
2 |
static short checkedCast(long value) Returns the short value that is equal to value, if possible. |
3 |
static int compare(short a, short b) Compares the two specified short values. |
4 |
static short[] concat(short[]... arrays) Returns the values from each provided array combined into a single array. |
5 |
static boolean contains(short[] array, short target) Returns true if target is present as an element anywhere in array. |
6 |
static short[] ensureCapacity(short[] array, int minLength, int padding) Returns an array containing the same values as array, but guaranteed to be of a specified minimum length. |
7 |
static short fromByteArray(byte[] bytes) Returns the short value whose big-endian representation is stored in the first 2 bytes of bytes; equivalent to ByteBuffer.wrap(bytes).getShort(). |
8 |
static short fromBytes(byte b1, byte b2) Returns the short value whose byte representation is the given 2 bytes, in big-endian order; equivalent to Shorts.fromByteArray(new byte[] {b1, b2}). |
9 |
static int hashCode(short value) Returns a hash code for value; equal to the result of invoking ((Short) value).hashCode(). |
10 |
static int indexOf(short[] array, short target) Returns the index of the first appearance of the value target in array. |
11 |
static int indexOf(short[] array, short[] target) Returns the start position of the first occurrence of the specified target within array, or -1 if there is no such occurrence. |
12 |
static String join(String separator, short... array) Returns a string containing the supplied short values separated by separator. |
13 |
static int lastIndexOf(short[] array, short target) Returns the index of the last appearance of the value target in array. |
14 |
static Comparator<short[]> lexicographicalComparator() Returns a comparator that compares two short arrays lexicographically. |
15 |
static short max(short... array) Returns the greatest value present in array. |
16 |
static short min(short... array) Returns the least value present in array. |
17 |
static short saturatedCast(long value) Returns the short nearest in value to value. |
18 |
static Converter<String,Short> stringConverter() Returns a serializable converter object that converts between strings and shorts using Short.decode(java.lang.String) and Short.toString(). |
19 |
static short[] toArray(Collection<? extends Number> collection) Returns an array containing each value of collection, converted to a short value in the manner of Number.shortValue(). |
20 |
static byte[] toByteArray(short value) Returns a big-endian representation of value in a 2-element byte array; equivalent to ByteBuffer.allocate(2).putShort(value).array(). |
Methods Inherited
This class inherits methods from the following class −
- java.lang.Object
Example of Shorts Class
Create the following java program using any editor of your choice in say C:/> Guava.
GuavaTester.java
import java.util.List; import com.google.common.primitives.Shorts; public class GuavaTester { public static void main(String args[]) { GuavaTester tester = new GuavaTester(); tester.testShorts(); } private void testShorts() { short[] shortArray = {1,2,3,4,5,6,7,8,9}; //convert array of primitives to array of objects List<Short> objectArray = Shorts.asList(shortArray); System.out.println(objectArray.toString()); //convert array of objects to array of primitives shortArray = Shorts.toArray(objectArray); System.out.print("[ "); for(int i = 0; i< shortArray.length ; i++) { System.out.print(shortArray[i] + " "); } System.out.println("]"); short data = 5; //check if element is present in the list of primitives or not System.out.println("5 is in list? " + Shorts.contains(shortArray, data)); //Returns the minimum System.out.println("Min: " + Shorts.min(shortArray)); //Returns the maximum System.out.println("Max: " + Shorts.max(shortArray)); data = 2400; //get the byte array from an integer byte[] byteArray = Shorts.toByteArray(data); for(int i = 0; i< byteArray.length ; i++) { System.out.print(byteArray[i] + " "); } } }
Verify the Result
Compile the class using javac compiler as follows −
C:\Guava>javac GuavaTester.java
Now run the GuavaTester to see the result.
C:\Guava>java GuavaTester
See the result.
