I have wrote program in java the program is to convert from KM to miles and miles to KM the program works fine but the problem is in the result in text area exceeded the area so does not appear the full text below the code attached. so i want if it is reached at the end of line it goes to new line
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
public class Converter extends JFrame implements ActionListener {
JLabel label = new JLabel("Distance : ");
JTextField input = new JTextField(10);
JButton button = new JButton("Convert");
JTextArea output = new JTextArea(10,15);
CheckboxGroup cbg = new CheckboxGroup();
Checkbox cb1 = new Checkbox("Convert MILES to KM", cbg, true);
Checkbox cb2 = new Checkbox("Convert KM to MILES", cbg, false);
public static void main(String args[]) {
Converter s = new Converter();
s.setVisible(true);
}
public Converter() {
setLayout(null);
setSize(300,400);
//left-down-width-hegiht
cb1.setBounds(60,30,150,30);
cb2.setBounds(60,60,150,30);
label.setBounds(30,90,120,30);
input.setBounds(90,95,170,20);
button.setBounds(100,130,90,30);
output.setBounds(45,168,200,165);
add(cb1);
add(cb2);
add(label);
add(input);
add(button);
add(output);
button.addActionListener(this);
}
public void actionPerformed(ActionEvent e) {
if (cb1.getState() ) {
if (e.getSource() == button) {
double d = Double.parseDouble(input.getText());
double d2 = d / 0.62;
String str2 = String.valueOf(d2);
output.setText(d + "miles equals to " + str2 + " kilometers");
}
}
if (cb2.getState()) {
if (e.getSource() == button){
double d = Double.parseDouble(input.getText());
double d2 = d * 0.62;
String str2 = String.valueOf(d2);
output.setText(d + " kilometers equals to " + str2 + " miles ");
}
}
}
}
If your goal is purely to have line wrapping on in the text area then you can make use of JTextArea's built-in function named setLineWrap.
Passing a true boolean value as a parameter to setLineWrap such as setLineWrap(true) will turn on line wrapping for the JTextArea component. Passing a false boolean value as a parameter will turn off line wrapping
In your code, it would be used as follows.
output.setLineWrap(true);
The Converter constructor will then look as follows.
public Converter() {
// Turn on line wrapping.
output.setLineWrap(true);
setLayout(null);
setSize(300, 400);
// left-down-width-hegiht
cb1.setBounds(60, 30, 150, 30);
cb2.setBounds(60, 60, 150, 30);
label.setBounds(30, 90, 120, 30);
input.setBounds(90, 95, 170, 20);
button.setBounds(100, 130, 90, 30);
output.setBounds(45, 168, 200, 165);
add(cb1);
add(cb2);
add(label);
add(input);
add(button);
add(output);
button.addActionListener(this);

I want to remove labell10 and combo box - level when I change from programing book item in combo box category. I already done similar coding and they are working. But in this case form remain lower parts of l10 and level. I just want to display JTextField agegroup and change text of l8 to age group when item art book selected in combo box category. And similarly l8 must be language and slanguage combo box must be display and text field agegroup must be removed when category is story book. Also need text field planguage and combo box level add if category is programing box. And when we change from one category to another previous displayed items must be removed.

As in my last question, I declare that I'm very new to coding and Java is my only current language.
I'm building my first entirely independent project in eclipse, using a lot of Java imports.
It is a POS till system, it has 24 menu item buttons which are labelled by taking a string that holds null value to begin with.
I have an admin panel and from this panel I can update the title and price associated with the menu item button.
When I click "set" button relating to that particular menu item button, the string and double for item name and price update properly but title printed on JButton does not change.
What am I doing wrong/missing please?

You could just create a String and then pass the value from that String into your action listener. Please find underneath a local String (should be an Instance, but for testing I have made a local one). And then I have passed it to the button.
if (source == menItSet1){
String text = setItem1.getText();
menitprice1 = Double.parseDouble(setPrice1.getText());
menuItem1.setText(text + " " + menitprice1);

How to append a scroll pane for my window?

Never add components directly to a scroll pane.
l1.setBounds(10,70,100,50);
Don't use setBounds(...). It is the job of the layout manager to set the size/location of the component.
The basic logic would be:
JPanel panel = new JPanel(); // set your layout manager for the panel.
panel.add( someComponent );
panel.add( anotherComponent );
JScrollPane scrollPane = new JScrollPane( panel );
frame.add( scrollPane );
Read the Swing Tutorial for Swing basics. Every section in the tutorial has working examples. Maybe start with the section on How to Use Scroll Panes.
This works, but you'll need to layout the components better..

Notes:
As mentioned by #camickr, setting the bounds of the components won't work reliably. Java GUIs have to work on different OS', screen size, screen resolution etc. using different PLAFs in different locales. As such, they are not conducive to pixel perfect layout. Instead use layout managers, or combinations of them along with layout padding and borders for white space.
Please try to solve programming errors before you've got to dozens of components! For simple testing of layouts with many components, just add dummy components in a loop. To put that another way: For better help sooner, post a Minimal, Complete, and Verifiable example or Short, Self Contained, Correct Example.
Safer to use logical font names that specific one, e.g. Algerian will only work on systems with that font installed!
I have used the following code to insert data into the mongodb database.....the problem with this i have to explicitly specify the data to be entered but however I need to do it dynamically...in the sense using a GUI, whatever has been entered int the text box must be put into the database.

"i have a front end which has 4 text boxes saying "name","manufacturer","colour" and "price"....so whatever i enter in the text box should be put into the database....however in the above code insertion can be done only by explicitly specifying the values....so i need to change this for a generlized method"
Just change it to something like:
String name = nameField.getText();
String manufacturer = manufacturerField.getText();
String color = colorField.getText();
String price = priceField.getText();
BasicDBObject doc = new BasicDBObject("title", "MongoDB").
append("name", name ).
append("manufacturer", manufacturer).
append("colour", color).
append("price", price);
coll.insert(doc);
