Source Code:

import java.io.*;
class Telcall
{
	String Phno,Name;
	int N;
	double Amt;
	Telcall(String s1,String s2,int x)
	{
	Phno=s1;
	Name=s2;
	N=x;
	Amt=0;
	}
	void compute()
	{
	if(N>=1 && N<=100)
	Amt=500;
	else if(N>=101 && N<=200)
	Amt=500+((N-100)*1);
	else if(N>=201 && N<=300)
	Amt=500+((N-100)*1.2);
	else if(N>300)
	Amt=500+((N-100)*1.5);
	}
	void dispdata()
	{
	System.out.println("Phone no.        Name       Total Calls     Amount");
	System.out.println(Phno+"       "+Name+"       "+N+"            "+Amt);
