Java中的 Double shortValue() 方法及示例
Double 类的shortValue()方法是一个内置方法,用于在类型转换后将调用对象指定的值返回为 short。
语法:
DoubleObject.shortValue()
返回值:它将 DoubleObject 的值返回为short 。
下面的程序说明了Java中的 shortValue() 方法:
方案一:
Java
// Java code to demonstrate
// Double shortValue() method
class GFG {
public static void main(String[] args)
{
// Double value
Double a = 17.47;
// wrapping the Double value
// in the wrapper class Double
Double b = new Double(a);
// shortValue of the Double Object
short output = b.shortValue();
// print shorting the output
System.out.println("Short value of "
+ b + " is : " + output);
}
}
Java
// Java code to demonstrate
// Double shortValue() method
class GFG {
public static void main(String[] args)
{
String value = "54.1";
// wrapping the Double value
// in the wrapper class Double
Double b = new Double(value);
// shortValue of the Double Object
short output = b.shortValue();
// print shorting the output
System.out.println("Short value of "
+ b + " is : " + output);
}
}
输出:
Short value of 17.47 is : 17
方案二:
Java
// Java code to demonstrate
// Double shortValue() method
class GFG {
public static void main(String[] args)
{
String value = "54.1";
// wrapping the Double value
// in the wrapper class Double
Double b = new Double(value);
// shortValue of the Double Object
short output = b.shortValue();
// print shorting the output
System.out.println("Short value of "
+ b + " is : " + output);
}
}
输出:
Short value of 54.1 is : 54
