This document outlines an introduction to programming with Java lecture, including installing Java development tools, the structure of Java programs, compiling and running programs, and printing output. It provides examples of basic Java print statements, escape sequences, common errors, and tips for programming. It assigns two basic exercises - to print formatted information for multiple persons and to print a quoted statement with an escape character.

Some Basics
Q. What is a program?
Ans. A sequence of instructions that a computer can interpret
and execute.
Step 1
Install Java Development kit (JDK)
Step 2
Install Jcreator( java platform)
Step 3
Connect the Jcreator with JDK version

Structure of Java Programs

6. nlp-ai@cse.iitb
“Test.java”
Example Program

7. nlp-ai@cse.iitb
Compiling & Running the Program

8. nlp-ai@cse.iitb
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
About Printing on the Screen

9. nlp-ai@cse.iitb
• Some common errors in the initial phase of learning
programming:
- Mismatch of parentheses
- Missing ‘;’ at the end of statement
- Case sensitivity
• The best way to learn programming is writing a lot of
programs on your own.
Some Tips About Programming

10. nlp-ai@cse.iitb
1. Write a program which prints the following information
about at least 5 persons:
NAME MAIL-ID EMPLOYEE-CODE PHONE
Eg. Umesh umesh@cse p03161 25764728
Salil salil@cse p03160 25764728
Each entry should be on a separate line.
2. Write a program that prints the following line on the screen
along with quotes.
“Can we print ‘’ with System.out.println() statement?”
