Java methods are similar to functions or procedures in other
programming languages.

Every Java program must have one main() method.

Here is the main() method from a Java program which prints
"Hello World":

public static void main (String[] args) {
// This Java program prints "Hello World!"
System.out.println{"Hello World!");


A constructor creates an Object of the class that it is in
by initializing all the instance variables and creating a
place in memory to hold the Object. It is always used with
the keyword new and then the Class name. For instance, new
String(); constructs a new String object.

COnstructors are basically used to initialize the attributes
of the class.
