U had not added semi colons after System.out.println etc. try this(i have not tried it on java as i don't have it installed. if error is still there then tell me in which line u r getting it and what does it say)

import java.io.*;
public class bill
{
double amt;
String cust_name;
double bill;
InputStreamReader ir = new InputStreamReader(System.in);
BufferedReader br = new BufferedReader(ir);
public void accept()throws IOException

{
System.out.println("APCPDCL");
System.out.println("Electricity bill");
System.out.println("enter the following and pay the bill");
System.out.println("*******************");
System.out.println("ENTER CUSTOMER'S NAME :");
String cust_name =br.readLine();
System.out.println();
System.out.println("enter customer's address :");
String add=br.readline();
System.out.println();
System.out.println("enter meter no.");

double mtr_no =Double.parseDouble(br.readLine(mtr_no));
System.out.println();
System.out.println("enter no. of units consumed");

double u=Double.parseDouble(br.readLine());
}
public void display ()
{
if(u<=400)
{
if(u<=50.0)
amt=(1.45*u);
else if((u>50.0)&&(u<=100.0))
amt =(1.45*50.0+((u-50.0)*2.80));
else if((u>100.0)&&(u<=200.0))
amt =(50*1.45)+(50*2.80)+((u-100.0)*3.05));
else if((u>200.0)&&(u<=300.0))
amt=(50*1.45)+(50*2.80)+(100*3.05)+((u-200*4.75));

}
else
{
System.out.println("invalid entry");
}
double bill = amt + 250.0;
System.out.println("------------------------------------");
System.out.println("monthly rental=Rs 250 /-");
System.out.println();
System.out.println("you need to pay RS"+bill );
