How to put integer value in JLabel?

Question

I need to display an integer onto JLabel, the following code does not work out well, even with Integer.parse().

How do I rectify it?

JLabel lblTemp = new JLabel("");
lblTemp.setBounds(338, 26, 46, 14);
contentPane.add(lblTemp);

//store int value of item clicked @ JList
int temp = list.getSelectedIndex() + 1;
lblTemp.setText(temp);   // <- problem

1) Java GUIs might have to work on a number of platforms, on different screen resolutions & using different PLAFs. As such they are not conducive to exact placement of components. To organize the components for a robust GUI, instead use layout managers, or [combinations of them](http://stackoverflow.com/a/5630271/418556), along with layout padding & borders for [white space](http://stackoverflow.com/q/17874717/418556). 2) For better help sooner, post an [SSCCE](http://sscce.org/). — Andrew Thompson, Oct 22 '13 at 06:16

Use String.valueOf method :

Returns the string representation of the int argument.

lblTemp.setText(String.valueOf(temp));

lblTemp.setText(String.valueOf(temp));

Your temp is an integer but the type that the setText(...) method accepts is String. You need to convert first your integer to String.

The quick and dirty solution for putting integers in places that expect strings is to do the following:

lblTemp.setText(temp + "");

I hope this helps.

setText() takes string as an argument. Use this line to code to convert int to string.

Integer.toString(number)

Hope it helps.

If you use Wrapper class Integer instead of primitive type int then you can get temp.toString() method that automatically convert to string value

You can Use String.valueOf() or Integer.toString() Methods

lblTemp.setText(String.valueOf(temp));

or

lblTemp.setText(Integer.toString(temp));
