Answer 1

// to display absolute value of number

public class Number

{

public static void main ( String args [] )

{

int n1 , n2 ;

double p = 0.0 , q = 0.0;

p = Math . abs ( n1 ) ;

q = Math . abs ( n2 ) ;

System.out.println ( " number 1 = " + p ) ;

System.out.println ( " number 2 = " + q ) ;

}

}

Answer 2

Answer:

The given program is written in Java.

    int a=sc.nextInt();

    System.out.println("Absolute value: "+Math.abs(a));

    sc.close();

 }
