Example of Shorts Class

使用您在 C:/> Guava 中选择的任何编辑器创建以下 java 程序。

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] + " ");
      }
   }
}

验证结果

使用javac编译器编译类，如下所示 −

C:\Guava>javac GuavaTester.java

现在运行 GuavaTester 查看结果。

C:\Guava>java GuavaTester

查看结果。

[1, 2, 3, 4, 5, 6, 7, 8, 9]
[ 1 2 3 4 5 6 7 8 9 ]
5 is in list? true
Min: 1
Max: 9
9 96
