Introduction to Java Language and Object oriented programming language

What is Java?

• A programming language specifies the words and symbols that we can use to write a program
• A programming language employs a set of rules that dictate how the words and symbols can be put together to form valid program statements
• The Java programming language was created by Sun Microsystems, Inc.
• It was introduced in 1995 and it's popularity has grown quickly since

Why Java is not C! 

• In C, almost everything is in functions
• In Java, almost everything is in classes
• There is often only one class per file
• There must be only one public class per file
• The file name must be the same as the name of that public class, but with a .java extension
