  6.  
  7.     printf("Enter an integer \n");
  8.     scanf("%ld", &number);
  9.     tempnum = number;
  10.     /*  left shift by two bits */
  11.     number = number << 2;
  12.     printf("%ld x 4 = %ld\n", tempnum, number);

Java programming language

Java, modern object-oriented computer programming language. Java was created at Sun Microsystems , Inc., where cofounder William (Bill) Joy led a team of researchers in an effort to create a new language that would allow consumer electronic devices to communicate with each other. Work on the language began in 1991, and before long the team’s focus changed to a new niche, the World Wide Web. Java was first used on the Web in 1994, and Java’s ability to provide interactivity and multimedia showed that it was particularly well suited for the Web. The difference between the way Java and other programming languages worked was revolutionary. Code in other languages is first translated by a compiler into instructions for a specific type of computer. The Java compiler instead turns code into something called Bytecode, which is then interpreted by software called the Java Runtime Environment (JRE), or the Java virtual machine. The JRE acts as a virtual computer that interprets Byte...
