Basic Java Program To Print Hello World

It is a basic JAVA program to say to the world "Hello World". It is example for beginners to understand basic java code.
The name Java was derived at a local coffee shop frequented by some of the members and it's related to coffee material.
So In this basic program print Hello WORLD inside the coffee mug.

First install JDK(JAVA Development Kit) with latest version because to run java program need JVM(java virtual machine) when you install JDK then JVM installed in your system.
Java Virtual Machine(JVM) makes JAVA as platform independent.

Hello World JAVA Program

Program Code

class hello   //create class hello
{
  public static void main(String[] args)  //main method 
  {
    System.out.println("\nExample to print HELLO WORLD in Coffee Mug\n");
    System.out.println(" _______\n|       |\n|       |__\n| HELLO"
+" |  |\n| WORLD |  |\n|       |__|    \n|       |\n|_______|");
  }
}

Save Program
Type the program code in notepad and save Java program with classname.java. In this program save as hello.java.
File name and class name must be same.

Compile Program
javac hello.java
When compile program then it creates bytecode named with hello.class. class file created in same location where program stored.
Bytecode is a code which as same as machine language code.

Exicute the Program
java hello
Now we execute the bytecode in the Java interpreter with using this command.

C Program to String Reverse

It is a basic C program to reverse a string.
In this c programming example user input a string and get reverse of accepted string.

Aim - C program to reverse accepted string [Using strrev function]

Program Code

//String Reverse using strrev function
#include"stdio.h"
#include"conio.h"
#include"string.h"
void main()
{
   char str[20];
   clrscr();
   printf("********* String Reverse Using strrev Function *******\n");
   printf("Enter a string:  ");
   gets(str);
   strrev(str);
   printf("\n Reverse string is:  %s",str);
   getch();
}

Output

Aim - C program to reverse accepted string [without using strrev function]

Program Code

//String Reverse without using strrev function
#include"stdio.h"
#include"conio.h"
#include"string.h"
void main()
{
 char str1[20],str2[20];
 int i,j=0;
 clrscr();
 printf("***********String Reverse*********\n");
 printf("Enter String:");
 gets(str1);
 for(i=strlen(str1)-1;i>=0;i--,j++)
 {
  str2[j]=str1[i];
 }
 str2[j]=NULL;
 printf("\nReverse String is:");
 puts(str2);
 getch();
}

Why C is Called Middle Level Language?

Why C is Called Middle Level Language?

C language supports high level language which is user friendly and low level language which is machine friendly.
C combines features of a high level language with the functions of an assembly level language. It reduces the gap between low level language and high level language.
So C language called as middle level language.

C contains many features of high level language like modular programming, user friendly, loop, arrays etc. C language is also related to machine level language(low). It provides features like access to memory using pointers and assembly aspects.
C is one of the language who able to directly interact to system.
C language is used to develop both user applications and operating systems.

Thus, C is called as Middle Level Language.
