Java 中的 longValue()方法
原文:https://www . geesforgeks . org/long-long value-method-in-Java/
java.lang.Long.longValue()是 java 中 Long 类的内置方法，它在转换后将 Long 对象的值作为 Long 返回。 语法:
public long longValue()
参数:该方法不取任何参数。 返回值:该方法将该对象表示的数值转换为长类型后返回。 示例:
Input: 5366623
Output: (Long) 5366623
Input: -6723887
Output: (Long) -6723887
Explanation:
When the number is passed in this object it will convert that
to long and gives the value like,
Long lobject = new Long(5366623)
It will return 5366623 as long.
下面的程序说明了 java.lang.Long.longValue()方法的工作原理。 程序 1: 为正数。
Java 语言（一种计算机语言，尤用于创建网站）
// Java program to illustrate the
// java.lang.Long.longValue() method
import java.lang.*;
public class Geek {
public static void main(String[] args)
{
Long lobject = new Long(77387187);
// It will return the value of this Long as a long
long nl = lobject.longValue();
System.out.println("The Value of nl as long is = " + nl);
Long lobject2 = new Long(-6723887);
// It will return the value of this Long as a long
long nl2 = lobject2.longValue();
System.out.println("The Value of nl2 as long is = " + nl2);
}
}
Output:
The Value of nl as long is = 77387187
The Value of nl2 as long is = -6723887
