Shorts 示例

使用所選擇的編輯器創建下面的java程序 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] + " ");
      }
   }
}

驗證結果

使用javac編譯器編譯如下類

C:\Guava>javac GuavaTester.java

現在運行GuavaTester看到的結果

C:\Guava>java GuavaTester

看到結果

[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
