Thread: Code having problems please help - Invalid method declaration, return type required.

Hi,
I have a code written in Java and the system is giving me an error "Invalid method declaration, return type required". Please help me to rectify this. Thanks.

import java.io.*;
class steve 
{
public static long perimeter_rectangle(int l,int b)
{
long x=2*(l+b);
return x;
}
public static long perimeter_square(int s)
{
long a=4*s;
return a;
}
public static void main (string args[]) throws IOException;
BufferedReader br=new BufferedReader(new InputStreamReader(System.in));
{System.out.println("1=perimeter of rectangle");
System.out.println("2=perimeter of square");
System.out.println("ENTER YOUR CHOICE");}
String str=br.readLine();
int S=Integer.parseInt(str);
Switch (S)
{
case 1:
{
System.out.println("enter the length n breadth");
String l=br.readLine();
int a=Integer.parseInt(l);
String b=br.readline();
int c=Integer.parseInt(b);
long x=perimeter_rectangle(a,c);
System.out.println(x);
break;
}
case 2:
{
System.out.println("enter d side");
String S=br.readLine();
int q=Integer.parseInt(s);
long a=perimeter_square(q);
System.out.println(a);
break;
}
default:
System.out.println("INVALID CHOICE");
}

Hi,

Can someone help in letting me know where the problem is in the Java code that I had put earlier in this thread. If 'string' is not a correct syntax, please let me know how I can get this script running fine as I am new to Java. Thanks.

Edit: And one post is enough. I have deleted your other thread - please read the forum rules and know that double posting is not allowed

You need to post the full text of the error message that you are getting if you want help fixing the problem.

what theyre saying is try changing

public static void main(string[] args){

to

public static void main(String[] args){

Java is case sensitive, so watch out.
