This solution is about Online Java Assignment Help it includes that the student are required to develop a Java Graphical User Interface (GUI) Application to demonstrate you can use Java constructs.
The main objective of this java assignment is to design and construct Graphical User Interfaces for the specified problem domain. I have used Java Beans software element and implemented the Java inheritance features as well. I have made both the programs as per assignment requirements.
The program that is to be made accepts one command line argument, which is the filename of the text to be read.
The example will be: java histogram <filename> where <filename> is the name of the input text file. The program then reads this file and calculates the histogram of each letter and displays the histogram in the following order:
- The total number of characters counted (only include AZ)
- The letters in upper case
- The occurrence of the letters and the percentage;
- It shows a series of asterisks showing the percentage of each occurrence
- The program outputs a vertical bar for every 10 asterisk

The output screen of the program accepts the filename as the parameter.
Write a program that displays the histogram using a GUI. The file name is entered from a text field. Pressing the Enter key on the text field or clicking on the view button causes the program to start to read and process the file and display the histogram. The histogram is displayed in the center of the window (see Figure 1). Note that you do not have to display the count or the percentage.
Here is the UML diagram for the GUI based program which will display the histogram
Below is the implemented code for the GUI based program:
