Day of the Programmer- HackerRank problem

 Math. abs it's a process that takes the accurate value from the user.

if the user give input x= -78

then if we use (Math.abs(x));

it' will be printed only x=78

Syntax:

1. public static int abs(int i)  
2. public static double abs(double d)  
3. public static float abs(float f)  
4. public static long abs(long lng)  

Parameters:

1. The argument whose absolute value is to be determined  

Return:

1. This method returns the absolute value of the argument 

Example 1:

1. public class AbsExample1  
2. {  
3.     public static void main(String args[])  
4.     {  
5.          
6.         int x = -48;  
7.         //print the absolute value of int type  
8.         System.out.println(Math.abs(x));  
9.     }  
10. }  

Output

48
