This document provides an introduction and overview for a lecture series on programming with Java. It outlines the topics that will be covered, including the structure of Java programs, input/output, conditional statements, loops, arrays, strings, and functions. It provides examples of a simple Java program that prints "Hello World" and explains how to compile and run a Java program. The document also includes sample questions, answers, and programming assignments.

Some Basics
Q. What is a program?
Ans. A sequence of instructions that a computer can interpret
and execute.
Q. Why Java and not Hindi / Marathi / English?
Ans. Since, so far, computer is not intelligent enough to
understand natural languages.

6. nlp-ai@cse.iitb
class class-name {
public static void main(String args[]) {
statement1;
statement2;
…
…
}
}
Structure of Java Programs

7. nlp-ai@cse.iitb
“First.java”
class First {
public static void main(String args[]) {
System.out.println(“Hello World”);
}
}
Example Program

8. nlp-ai@cse.iitb
Compiling: is the process of translating source code written in
a particular programming language into computer-readable
machine code that can be executed.
$ javac First.java
This command will produce a file ‘First.class’, which is used
for running the program with the command ‘java’.
Running: is the process of executing program on a computer.
$ java First
Compiling & Running the Program

9. 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

10. 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

11. 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?”
