General Java Help

[Steel546]

Heyyy, I'm back. Getting the hang of this java thing. Anyways, I have a few questions, I'll leave my hardest for last.

So, I believe I'm having an overloading method issue here.

public static boolean closeAccount (double acctBalance, int checksLeft) {
    // returns true if acctBalance is less than zero or checksLeft is less than or equal to zero.

    if (acctBalance < 0 || checksLeft <= 0){
        return true;}
        else{
            return false;
        }
    }

}
*public static boolean closeAccount (int acctBalance, int checksLeft) {
    // returns true if acctBalance is less than zero or checksLeft is less than or equal to zero.

    if (acctBalance < 0 || checksLeft <= 0 ){
 *       return true;}
    else{
 *       return false;
    }

}

I'm getting a "class, interface, or enum expected" error on the lines with asterisks. I'm creating overloading methods, but I believe that as long as the arguments are different, then I'm okay. I have a double/int in the first (fine) and a int/int in the second. Little confused.

And lastly... how do you launch a browser? I've been searching, and there seems to be no basic answer to this.

import com.apple.mrj.MRJFileUtils;
import java.io.*;

public class Main {

  String url = "http://www.google.com/";
    
    public static void main(String[] args) {new
Open();
    }
Open() {
try {
MRJFileUtils.openURL(url);
} catch (IOException ex) {}
  }


    }

Man... that's ugly. Anyways, but that's for a Mac. Instead, I'm trying to make a method to call instead of putting it under the main argument. Anywho, I'll keep working on that one. As always, any suggestion is greatly appreciated.

Wait, found something.

URLDisplayer.getDefault().showURL(URL url);

[Steel546]

Nevermind, fixed it.

import java.io.*;

public class KyleTaylorToolBox {

    public static void printEveryXtoY (int x, int y) {
   // this method prints every xth integer from 0 to y that is less than or equal to y.
   // example output when passed (4,14): 0  4  8  12
   // example output when passed (2, 14): 0  2  4  6  8  10  12  14
int count = 0;
          while (count <= y) {
               System.out.println( + count);
               count = count + x;
          }


    }

 public static void launchBrowser ( ) throws IOException {
    // this method starts a web browser like Internet Explorer. Search the Internet for help.
 String url="http://www.cse.unt.edu";
 Runtime.getRuntime().exec("rundll32 url.dll,FileProtocolHandler " + url);
 

 }

public static boolean isOdd (int x) {
    // this method returns true if x is odd and false if x is even.
    if (x % 2 == 0){
        return false;}
        else{
            return true;
        }
    }

//Create two overloaded methods called closeAccount:

public static boolean closeAccount (double acctBalance, int checksLeft) {
    // returns true if acctBalance is less than zero or checksLeft is less than or equal to zero.

    if (acctBalance < 0 || checksLeft <= 0){
        return true;}
        else{
            return false;
        }
    }

public static boolean closeAccount (int acctBalance, int checksLeft) {
    // returns true if acctBalance is less than zero or checksLeft is less than or equal to zero.

    if (acctBalance < 0 || checksLeft <= 0 ){
        return true;}
    else{
        return false;
        }

    }
}

Okay. Now I'm having problems calling the methods in a different class. Says "cannot find symbol".

You forgot to import KyleTaylorToolB ox class in other class

Okay. Now I'm having problems calling the methods in a different class. Says "cannot find symbol".

I'm sure 'it' said a lot more, e.g. the symbol it couldn't find and where it couldn't find it (including the line number). That should give you some clues.

kind regards,
