public class HelloWorld – is a class file that you will use to start programming your java program. Within the ‘{}’ of HelloWorld class is where all the relevant codes of that class file/program will be in.
public static void main(String[] args) – we need this method as a default method because Java needs to know where to start the execution the codes. Without this the Java will not know. This line is also known as a method header named ‘main’ and the code inside the ‘{}’ is known as method body.
System.out.println(“Hello world”); – the system outputs by printing the “Hello world” message. Print is a built-in method and helps to print out the statement inside the ‘()’.
