- 2. 1. Java is Object-Oriented • Object-oriented programming provides great flexibility, modularity, clarity, and reusability through encapsulation, inheritance, and polymorphism. 2. Java Is Distributed • Distributed computing involves several computers working together on a network. • Java is designed to make distributed computing easy as networking capability is inherently integrated into Java. • Thus, writing network programs is like sending and receiving data to and from a file. CHARACTERISTICS OF JAVA
- 3. 3. Java Is Interpreted • You need an interpreter to run Java programs. • The programs are compiled into the Java Virtual Machine code called bytecode. • The bytecode is machine-independent and can run on any machine that has a Java interpreter, which is part of the Java Virtual Machine (JVM). 4. Java Is Robust • Java compilers can detect many problems that would first show up at execution time in other languages. • Java has a runtime exception-handling feature to provide programming support for robustness. CHARACTERISTICS OF JAVA
- 4. 5. Java Is Secure • Java implements several security mechanisms to protect your system against harm caused by stray programs. 6. Java Is Architecture-Neutral • Write once, run anywhere. With a Java Virtual Machine (JVM), you can write one program that will run on any platform. 7. Java Is Portable • They can be run on any platform without being recompiled. CHARACTERISTICS OF JAVA
- 5. Set path to JDK bin directory set path=c:Program Filesjavajdk1.6.0 bin Set classpath to include the current directory set classpath=. Compile javac Welcome.java Run java Welcome COMPILING AND RUNNING JAVA FROM THE CMD
- 6. 1. System.out.println(“Hello World”); – outputs the string “Hello World” followed by a new line on the screen. 2. System.out.print(“Hello World”); - outputs the string “Hello World” on the screen. This string is not followed by a new line. 3. Some Escape Sequence – • n – stands for new line character • t – stands for tab character PRINTING ON THE SCREEN
