After moving to the page, type the code to compile and execute. When compiling and executing, authentication like the image below will be displayed, so enter it
This time I ran a program that displays the most basic Hello World The sample code is shown below.
public class HelloWorld｛ public static void main(String args)｛ System.out.println ("Hello World"); ｝ ｝
The execution result is displayed at the bottom of the screen.
This time I had to create a program as an issue when I didn't have a PC, so I actually used it, but the specifications were perfect for writing a basic program. However, image authentication is performed again for compilation and execution, it is a little difficult to see unless there is a certain screen size to write code, and when typing code, input on the smartphone is when typing on the keyboard It is a little difficult to hit because it changes a little.
