Java - Short class with Examples
Introduction
Java Short 类将一个短整形的原语类型值包装进一个对象中。Short 类型的对象包含一个类型为短整形的字段。
The Java Short class wraps a value of primitive type short in an object. An object of type Short contains a single field whose type is short.
Class Declaration
以下是 java.lang.Short 类声明 −
Following is the declaration for java.lang.Short class −
public final class Short
extends Number
implements Comparable<Short>
Field
以下是 java.lang.Short 类字段 −
Following are the fields for java.lang.Short class −
-
static short MAX_VALUE − This is the constant holding the maximum value a short can have, 215-1.
-
static short MIN_VALUE − This is the constant holding the minimum value a short can have, -215.
-
static int SIZE − This is the number of bits used to represent a short value in two’s complement binary form.
-
static Class<Short> TYPE − This is the Class instance representing the primitive type short.
Methods inherited
此类从以下类中继承方法:
This class inherits methods from the following classes −
-
java.lang.Object
Example
以下示例演示如何使用 Short 类从字符串获取 short。
The following example shows the usage of Short class to get short from a string.
package com.tutorialspoint;
public class ShortDemo {
public static void main(String[] args) {
// create a String s and assign value to it
String s = "+120";
// create a Short object i
Short i;
// get the value of short from string
i = Short.valueOf(s);
// print the value
System.out.println( "Short value of string " + s + " is " + i );
}
}
让我们编译并运行上述程序,这将生成以下结果 −
Let us compile and run the above program, this will produce the following result −
Short value of string +120 is 120
