Guava – Shorts.hashCode()方法及实例

Guava – Shorts.hashCode()方法及实例

Shorts.hashCode() 是Guava库中Shorts类的一个方法,用于返回一个短值的哈希代码。hashCode是一个唯一的整数值,是由编译器为一个对象计算的。如果对象的值没有变化,它将保持不变。

语法:

public static int hashCode(short value)

参数: 这个方法需要一个强制性的参数值,它是一个短值,要找到这个短值的hashCode。

返回值: 该方法返回一个整数值,即指定值的哈希代码。

下面的程序说明了上述方法的使用。

例1:

// Java code to show implementation of
// Guava's Shorts.hashCode() method
  
import com.google.common.primitives.Shorts;
import java.util.Arrays;
  
class GFG {
  
    // Driver's code
    public static void main(String[] args)
    {
  
        // Using Shorts.hashCode() method to
        // get the hash code for value
        System.out.println("HashCode value of 15: "
                           + Shorts.hashCode((short)15));
    }
}

输出:

HashCode value of 15: 15

例2:

// Java code to show implementation of
// Guava's Shorts.hashCode() method
  
import com.google.common.primitives.Shorts;
import java.util.Arrays;
  
class GFG {
    // Driver's code
    public static void main(String[] args)
    {
        // Using Shorts.hashCode() method to
        // get the hash code for value
        System.out.println("HashCode value of 10: "
                           + Shorts.hashCode((short)10));
    }
}

输出:

HashCode value of 10: 10
