Hey @Nitya_Somani
logic is fine
just use Single Scanner
Correct code :
import java.util.*;

import java.util.Scanner;

public class Main {
public static void main(String args[]) {
// Your Code Here

	Scanner scan1= new Scanner(System.in);
	int fmin=scan1.nextInt();
	
//	Scanner scan2=new Scanner(System.in);
	int fmax=scan1.nextInt();
	
//	Scanner scan3=new Scanner(System.in);
	int fstep=scan1.nextInt();
	

	int fcurrent = fmin;
	
	while(fcurrent <=fmax)
	{
		int celsius = (int)((5.0/9)*(fcurrent-32));
		System.out.println(fcurrent +"\t"+ celsius);
		fcurrent =fcurrent+fstep;
	}
}

}
