Java 中的短 hashCode()方法,带示例

原文:https://www . geesforgeks . org/short-hashcode-method-in-Java-with-examples/

短类hashCode() 方法是 Java 中的内置方法,用于返回 ShortObject 的哈希代码。

注意:hashCode()返回的值与 intValue()相同。

语法

ShortObject.hashCode()

返回值:返回一个 int 值,代表指定 Short 对象的 hashcode。

下面是 hashCode()方法在 Java 中的实现:

例 1:

// Java code to demonstrate
// Short hashCode() method

class GFG {
    public static void main(String[] args)
    {

        String value = "74";

        // wrapping the short value
        // in the wrapper class Short
        Short b = new Short(value);

        // hashCode of the Short Object
        int output = b.hashCode();

        // printing the output
        System.out.println("HashCode of "
                           + b + " : " + output);
    }
}

Output:

HashCode of 74 : 74

例 2:

// Java code to demonstrate
// Short hashCode() method

class GFG {
    public static void main(String[] args)
    {

        String value = "-17";

        // wrapping the short value
        // in the wrapper class Short
        Short b = new Short(value);

        // hashCode of the Short Object
        int output = b.hashCode();

        // printing the output
        System.out.println("HashCode of "
                           + b + " : " + output);
    }
}

Output:

HashCode of -17 : -17
