The fundamental structure of any Java programme should look like:
[package declarations]
[import statements]
[class declaration]
An example is given below:
package abc;
import java.lang;
class Demo {
public static void main(String[] args) {
Sytem.out.println("Hello! World");
}
}
//The file containing this class must be named Demo.java
A Typical Java class would have the following.
Package statement
import statements
Class comments (Optional)
Class Declaration {
Instance variable declarations
Constructor declaration
Method declarations
}

Let us see now how the simple java program will look like.
You can use any editor like notepad or any Java IDE for writing java programs.
/*
This is a sample java program
Save this file as Welcome.java
*/
class Welcome
{
// A java program will start from here.
public static void main(String args[])
{
System.out.println(" Welcome to Java-Sample!!! ");
}
}
For those who are using the IDE, you can follow the instructions have given by there.
Suppose if you are entering your program in notepad, then save this file as Welcome.java
The structure of Java Program are as under
1) Package
2) Class declaration
3) Method declaration
