The Java course internship mainly aimed to summarize and outline the content and purpose of the successful Java course design. The purpose and task of the internship were focused on helping students to master the basic knowledge of Java language programming and apply it skillfully. This included mastering the software design thoughts, methods, and steps of object-oriented development in Java, becoming proficient in class declaration and object usage, strengthening understanding of class inheritance, interfaces, and the application of variables and arrays, and learning about the design of graphical user interfaces in JAVA, and using JAVA to write a simple calculator program.
The basic idea of the program implementation was to write a simple calculator program with functions for inputting numbers 0-9 and π, addition, subtraction, multiplication, division, square root, trigonometric and inverse trigonometric functions, e^x, ln(x), lg(x), tanh, angle and radian transformation, delete, and clear functionality.
The overall design involved creating a graphical user interface with a text box and 32 buttons, using the BorderLayout layout. The text box was placed at the top of the interface. The numbers 0-9 and "." buttons were placed in a panel and laid out using GridLayout(4,3). Then they were added to a...."
Overall, the internship aimed to give students a solid understanding of Java language programming and the ability to apply it effectively, as well as practical experience in designing and implementing a simple calculator program using Java. This would be a crucial demonstration of their mastery of the course content and their readiness to enter the field as Java programmers.
