Answer 1

What is java?



Java is a programming language made by sun



What are it's best features?



Programs written in Java work in any operating system that has a Java Runtime Environment (JRE)

Read the java article for more

Automatic Garbage Collection collects no-longer used memory and properly disposes of it.

Completely class oriented.



What are it's worst features?



Programs written in Java have a reputation for being slower and requiring more memory than those written in some other languages

No unsigned integer type.



What does it do?



Java is a language. it does not do anything on it's own.



What is it's purpose?



A programmer writes a program in Java. An example of a java command is:

System.out.println("Hello World");

which would output "Hello World" to the screen and then go to the next line when run.



The programmer, after completing his program, use a compiler to convert his code from the language he understands to code that the computer can run.



The programmer can then distribute his program to clients. When they want to run his program, the Java Runtime Environment starts up and runs the program. Since almost every operating system has a Java Runtime Environment the user can install, the same program may work in those operating systems. Other languages require that you re-program or switch language to run the program in other operating systems.

4. Anything you can program it to do.

5. It allows you to program (and therefore sell) software for both Windows and Mac computers, increasing the possibility of expanded market share in the software market.

Answer 3

this could be a without postpone forward difficulty. you need to use the swap fact. First you'll want the Reader type to study the enter from the console. After analyzing the enter you may examine like under :- char enter = reader.getChar(); swap(enter) { case 'n': case 'N': // do the job you elect to do via pressing n button from the keyboard. ruin; case 'c': case 'C': // to do code ruin; ... /* examine like this for all conceivable circumstances */ ... default: equipment.out.println("That novel isn't on the record"); ruin; }

Answer 4

Its a programming language. It makes programs. Its purpose is to make programs.
