A Simple Java Program

-
Step 1:- Open notepad.

Step 2:- Write this code.
           
public class hello
{
public static void main(String arg[])
{
System.out.println("Hello this smart programmeron.blogspot.in");
}
}


Step 3:- Save As-> Hello.java

Step 4:- Press windows+R.
Step 5:- Type cmd and hit enter to open Command Prompt.
Cmds are:=
              >  d:     ------  to change from C:\Users\Amit to D:\   drive .
              > cd  java          ----- to goto folder java where my hello.java file was saved.
              > javac hello.java     ---->> to compile the hello.java file which you I have save in D:\java

                         After compile hello.java, You will find another file with extension .class.
                        Here I have hello.class because in this code I wrote public class hello{}

              > java hello   and hit the enter and your program will  run...

Note: - Please run that .class file in which you have write public static void main(String arg[]) another wise cmd.exe show an error this 'main' is not found.

Programming Rules

-
A programmer while writing a program should follow following rules. Every program should have main() function. C statements should be terminated by a semi-colon (;). At some place, a comma operator is permitted. If only a semi-colon is placed it is treated as a statement. For example:-                          while(condition)                          ; The above statement generates infinite loop. Without semi-colon the loop will not execute. An unessential semicolon if placed by the programmer is treated as an empty statement. All statements should be written in lowercase letters. Generally, uppercase letter are used only for symbolic constants. Blank space my be inserted between the words. This leads to improvement in the read-ability of the statements. However this is not applicable while declaring a variable, keyword, constant and function. It is ...
