JAVA Illegal Start of Expression Error
Could someone please help me out. I have an illegal start of an expression error at line 8 in the following code.
package untitled5;
public class Untitled1 {
public static void main(String[] args) {
public static void main(String[] args) {
int start_system, add_modify, add_modify_animal_data, report,
exit_system;
int check = menu();
while (check != 4) {
if (check == 1) {
add_modify_data();
}
else
if (check == 2) {
add_modify_medical_data();
}
else
if (check == 3) {
report();
}
check = menu();
}
exit_system();
System.exit(0);
}
{
public static void start_system() {
System.out.println("Start_system now");
}
}
//sets up the output
public static int menu() {
int check;
String output = "Modify Animal Data" + "\n " +
"1. Add/Modify Animal Data " + "\n" +
"2. Add/modify Meical Data " + "\n" +
"3. Report Section " + "\n" +
"4. Exit " + "\n " + "\n " + " Enter Your Selection:";
String scheck = JOptionPane.showInputDialog(null, output, " ",
JOptionPane.QUESTION_MESSAGE);
check = Integer.parseInt(scheck);
return check;
}
public static void add_modify() {
int check1;
while (check1 != 4) {
if (check1 == 1) {
add_animal_data();
}
else
if (check1 == 2) {
delete_animal_data();
}
else
if (check1 == 3) {
change_animal_data();
}
check1 = menu();
}
exit_system();
System.exit(0);
String output = "Modify Animal Data " + "\n " +

String scheck = JOptionPane.showInputDialog(null, output, " ",
JOptionPane.QUESTION_MESSAGE);
check1 = Integer.parseInt(scheck);
}
public static void add_modify_medical_data() {
int check2;
while (check2 != 4) {

public static void report() {
System.out.println("in Report");
}
public static void exit_system() {
System.out.println("in exit system");
};
}
}
Thank you
of course you are. :)
You really need to check your combination of open and close brackets. You must have an equal amout of both and you must fallow the java rules for declaration of attributes and methods.
I would recommend picking up a basic java book to learn these rules.

Arn't the smiles here about the most evil things you've ever seen? The normal smile looks like he just took you for all you're worth.

True it's more like a condescending smirk, I don't care tho... I like to antognise people...it's fun either way. :)
hi can anyone help me please. I'm having problem with my program. It's only one error illegal starts of expression in public void check (), at line 53. What it is mean?..
import javax.swing.JOptionPane;
//public class waiter{
//public static void main(String [] args)
class waiter
{
private double tab;
public waiter(String name);
{
System.out.println("My name is "+ name +", and i'll be your waiter!");
tab = 0.0;
}
public double priceof(String s);
{
double price;
if (s.equals("Chicken"))
{price = 5.95;}
else
{//burger fries
if (s.equals("burger"))
{price = 4.95; }
else
{price = 1.95;}
}//burger or fries
return price;
}//priceof
public void order(String s)
{
if(s.equals("Chicken"))
{
tab = tab + 5.95;
}// burger fries
else
{//burger fries
if (s.equals("Burger"))
{
tab = tab + 4.95;
}
else
{
tab = tab + 1.95;
}
}//price of
public void check()
{
System.out.println("Please pay $" + tab+",null");
}
}//end of class waiter
public class objects3
{
public static void main(String [] args)
{
waiter ourwaiter;
ourwaiter = new waiter ("Manfred");// makes a waiter object
double x; //to hold price of burger
double y; //varikable to hold price of chicken
x = ourwaiter.priceof("burger");
y = ourwaiter.priceof("chicken");
if (x<y)// buy cheaper product
{
System.out.println("I'll take the burger because it's cheaper");
ourwaiter.order("Burger");
}//burger
else
{
System.out.println("I'll take the chicken. ");
ourwaiter.order("chicken");
}//chicekn
System.out.println("And i'll have fries with that");
ourwaiter.oreder("Fries");
System.out.println("\n eat eat....\n");
ourwaiter.check();
}//main
}//class objects3use code tags if you want people to read your code.
And don't go hijacking other peoples' threads, not even old ones like this.

}As Jwenting mentioned, you need to start a new thread with your question and place your code between code tags to make it more readable. See the post at the top of the forum about code tags.
An illegal start of expression means that you have misformatted your code and it cannot be parsed correctly. This would include things like missing braces or parens, declaring a method within a method, missing semi-colon, etc.

Please read the following about code tags
Hey, this thread actually HELPED me...I'm a newbie to Java. I didn't realize I was trying to declare a method from within another method. Java can be difficult to debug sometimes although the NetBeans IDE is VERY helpful.
I am trying to write a program that reads three integers and prints their average. This is what I got so far, but every time I go to compile this program so that I can run it I keep receiving one error message in reference to the "system.out..." statement saying that it is an illegal start of expression. This maybe something simple that I turned into difficult. Am I going about this the right way? Please help.
public class IntApp
{
public static void main (String[] args)
{
final int BASE = 3;
AVER = (x + y + z) / BASE;
int x = 95;
int y = 85;
int z = 99;
System.out.println ("The average of int xyz: " + AVER +);
}
