java.lang.Long signum(long i)
Description
Make a note that the signum() method of Long class is static thus it should be accessed statically which means the we would be calling this method in this format:
Long.signum(method args)
Non static method is usually called by just declaring method_name(argument) however in this case since the method is static, it should be called by appending the class name as suffix. We will be encountering a compilation problem if we call the java signum method non statically.
Method Syntax
public static int signum(long i)
Method Argument
| Data Type | Parameter | Description |
|---|---|---|
| long | i | the value whose signum is to be computed |
Method Returns
The signum(long i) method of Long class returns the signum function of the specified long value.
Compatibility
Requires Java 1.5 and up
Java Long signum(long i) Example
Below is a simple java example on the usage of signum(long i) method of Long class.
package com.javatutorialhq.java.examples;
import java.util.Scanner;
/*
* This example source code demonstrates the use of
* signum(long i) method of Long class
*/
public class LongSignumExample {
public static void main(String[] args) {
// Ask for user input
System.out.print("Enter a value:");
// declare a scanner object to read the user input
Scanner s = new Scanner(System.in);
// assign the input to a variable
long value = s.nextLong();
// get the signum function
long result = Long.signum(value);
// print the result
System.out.println("Result:" + result);
// close the scanner object
s.close();
}
}
