If you want to use the method in Java console.log(), you can create a Consoleclass and add a static log()method. This method has a print statement to print a message to the console.
After creating the class, you can call log()methods by the class name. See the example below.
public class SimpleTesting {
public static void main(String[] args) {
Console.log("Hello DelftStack");
}
}
class Console {
public static void log(Object obj) {
