Write a Program to Calculate Absolute Value of a Number in Java Using Buffered Reader

import java.io.*;
import java.lang.Math;

class absolute
{
public static void main (String args[]) throws IOException
{
int a;
float b;
long c;
double d;


InputStreamReader ir=new InputStreamReader(System.in);

BufferedReader br =new BufferedReader(ir);

System.out.println("Please Enter the Integer Value");

a=Integer.parseInt(br.readLine());

System.out.println("Please Enter the Float Value");

b=Float.parseFloat(br.readLine());

System.out.println("Please Enter the Long Value");

c=Long.parseLong(br.readLine());

System.out.println("Please Enter the Double Value");

d=Double.parseDouble(br.readLine());


System.out.println(" Integer Absolute Value =" +Math.abs(a));

System.out.println(" Float Absolute Value =" +Math.abs(b));

System.out.println(" Long Absolute Value =" +Math.abs(c));

System.out.println(" Double Absolute Value =" +Math.abs(d));

}
}

--------------------Output--------------------

Please Enter the Integer Value
-9
Please Enter the Float Value
-90.89
Please Enter the Long Value
-8987777
Please Enter the Double Value
-78.90888
 Integer Absolute Value =9
 Float Absolute Value =90.89
 Long Absolute Value =8987777
 Double Absolute Value =78.90888


Process completed.
