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

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?”
