Explanation of Solution
Displaying an image of file in a label:
- In Java GUI application, images can be displayed in label or buttons.
- To display an image in a label, user must implement the below requirement.
- First create an object of “ImageIcon” class which is used to read the content of given image file.
- Then pass the object of “ImageIcon” as an argument to “JLabel” class.
- User can add the image to the existing label using “setIcon” method.
- This method takes the parameter of “ImageIcon” object.
Example:
The example for displaying an image in a label is shown below:
//Create an object of "ImageIcon"
ImageIcon sampleImage = new ImageIcon("sample.jpg");
//Create label and pass the object of "ImageIcon" to it
JLabel exampleLabel = new JLabel(sampleImage);
//Add an image to existing label
exampleLabel.setIcon(sampleImage);
From the above code,
- First line implies create the “ImageIcon” object with parameter of image file “sample.jpg”.
- Second line create the label using “JLabel” class and then pass the object of image icon as an argument to label class constructor...

Check out a sample textbook solutionStudents have asked these similar questions
a textbox for an optional search term, and a file upload field which allows them to upload a file which contains multiple lines of text (with the file each line should be treated as a separate string).
The user can enter a string and upload a file in the same submission of the form.
For the single string: if a search term is provided, output the string with the search term highlighted (by wrapping the term in a span with an appropriate class).
For the file upload:, if a search term is provided output only the strings that contain the search term (with the search term highlighted) and a count of the number of strings that did not have the term.
please do this in PHP and HTML only
Button Toggle
How can we make a button that toggles a text view (not the button label) between "Howdy Class!" and "You Pressed Me!"? Please write the java onClick function that would be specified in the button onClick property. Do not use string comparison to determine the current state. Also, do not use hard code string values.
In java pls
