Syntax error on token(s), misplaced construct(s) Code Help Needed

Question

I use eclipse to help me code & I have been having issues with the error message \"Syntax error on token(s), misplaced construct(s)\" coming up, I\'m not entirely sure what

Answer 1

public static void main(String args[]) is a method it needs to create a block with curly braces. It doesn't contain the block in the ThreadsUnitProject1 class.

public static void main(String args[]){}

Also the import statements should be outside the class declaration.

Full Example

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;

public class ThreadsUnitProject1 {

    public static void main(String args[]) {
    }

    class InvalidAgeException extends Exception {
        private static final long serialVersionUID = 1L;

        public InvalidAgeException() {
            super("The age you entered is not between 0 and 125");
        }
    }

    class QuestionOne extends Thread {
        public void main(String args[]) {
            System.out.println("What is your name?");

            BufferedReader br = new BufferedReader(new InputStreamReader(
                    System.in));
            String name = "";

            try {
                name = br.readLine();
            } catch (IOException e) {
                System.out.println("Error: " + e);
                System.exit(1);
            }

            System.out.println("Hello " + name + ", how old are you?");

            String i;
            int age;

            try {
                i = br.readLine();
                age = Integer.valueOf(i);
            } catch (IOException e) {
                System.out.println("Error: " + e);
                System.exit(1);
            } finally {
                System.out.println("No errors found.");
            }
        }
    }
}

Answer 2

Use {} after public static void main(String args[]), not ;.
