If Statements

[WillHorne]

I'm adding this text box and button to a Java Applet i'm making

no matter what i enter into the textbox, the only thing it prints is "No match"

any idea where i'm going wrong?

Thanks

import java.applet.Applet;
import java.awt.Button;
import java.awt.TextField;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;



	public class button extends Applet  implements ActionListener
	{	
	
		//TEXT BOX AND BUTTON
			 
		     Button okButton;								   					
		     TextField nameField;
		     {
		    	setLayout(null);
		        okButton = new Button("Search");
		        
		        nameField = new TextField("",100);
		     }

		        {
		          okButton.setBounds(140,20,160,25);
		          nameField.setBounds(20,20,100,25);
		        } 

		        {
		      add(okButton);
		      add(nameField);
		      okButton.addActionListener(this);
		     }
		        public void actionPerformed(ActionEvent e) {
		        	
if (nameField.equals("Resturant")) 
System.out.println("All Resturants Have Air-Conditioning");

else if (nameField.equals("Picnic Area")) 
	System.out.println("All Picnin Areas are non-Smoking");

else if (nameField.equals("Play Areas")) 
	System.out.println("All Play Areas are for Under-12's");

else if (nameField.equals("Lakes")) 
	System.out.println("All Lakes are Non-Swimming");

else if (nameField.equals("River")) 
	System.out.println("River is deep, Keep small children away from edge");

else 
	System.out.println("No Match");

Check this line:

nameField.equals("Picnic Area") {

nameField is a TextField object and will never "equal" a String. Perhaps instead you would like to extract the text held by the nameField and test that against your Strings. The API for TextField will tell you which method to use (actually, it's a method of its parent class, TextComponent).

Question -- is this for a school assignment or a personal project?

if (nameField.equals("Resturant"))

This line compares the text field nameField with the string "Resturant" and, of course, they are never equal because strings and text fields are different things. You should compare the string "Resturant" with the string returned by the text field:

if(nameField.getText().equals("Resturant")) {
    System.out.println("whatever");
}

Note also the use of braces - these are a good idea even with one line blocks of code.

Also when you post code, use the "code" tags. You put [code] at the start of the code and [/code] at the end. That way the code will be nicely formatted when it appears here.

this is for a website a friend is building

is there any way that you can get it to display to the applet rather than the console?

[WillHorne]

also when i put it into the main applet program it tells me that "void is an invalid type for the variable
actionPerformed" despite it working in its own project

public void actionPerformed(ActionEvent e)

any suggestions on why that might be?

then don't use Applet but move up to Swing with a JApplet. Or perhaps better still, use Java Web Start and a Swing application.

Go through the Swing tutorials as it will show you how to create full-fledged GUI's.

Are you trying to nest one method into another? Because this can't be done in Java. How much Java do you know? You probably should go through the introductory tutorials before trying to tackle GUI coding because without the foundations you may be in for a world of frustration.

yea that just clicked

i'd been up for about 36 hours at that point and things were a bit fuzzy

Ive been going through the JLabel and still don't have much of an idea how they fit together

could you give me a working example of how the code fits together

Thanks
