10. Revision
10

11. Sample of Java Application Program
11
VIEW SOURCE
RUN PROGRAM CODE

12. Source Code
12
Name of the class / programs
The “main” method

13. Why Java?
13
“Write once, Run Anywhere”
Security
Network-centric Programming
Dynamic, Extensible Program
Internationalization
Performance
Programmer efficiency and time-to-Market

14. Java: Names & Reserved Names
14
Legal name (variables, method, fields,
parameter,class, interface or package)
Start with:
Letter/dollar sign($)/ underscore (_)/ digits(0-9)
Reserved names
abstract char else goto long public
assert class extends if native return
boolean const false implements new short
break continue final import null static
byte default finally instanceof package strictfp
case do float int private super
catch double for interface protected switch

15. Java Naming Conventions
15
Names of variables, fields, methods:
Begin with lowercase letter
shape, myShape
Name of classes and interfaces:
Begin with UPPERCASE letter
Cube, ColorCube

16. 16
Named constants:
Written fully in UPPERCASE
Separated by underscore (_)
CENTER, MAX_VALUE, MIN_VALUE
If name is composed of several words:
First word begins with lowercase, first letter of
second word begins with UPPERCASE, the rest
back to lowercase
setLayout,addPatientName

17. Comments
17
Have no effect on the execution of the program
2 forms:
one-line comments
E.g.
Class Comment {
// This is one-line comment, its extends to the
end of line }
delimited comments
E.g.
Class Comment {
/* This is a delimited comment,
extending over several lines
*/

18. Types
18
Primitive type
E.g.
boolean,char,byte,short, int, long,float,double
Reference type
Class type defined/ interface type defined
Array type
In form [ ]

19. Variables
19
Syntax
<Variable-modifier>< type>< variables_name>;
E.g.
public static void main (String[] args){
int a, b,c;
int x=1, y=2,z=3;
int myDivide=z/x;
double PI=3.1415;
boolean isFound=false;
}

20. Declaring Variables
20
int x; // Declare x to be an
// integer variable;
double radius; // Declare radius to
// be a double variable;
char a; // Declare a to be a
// character variable;

21. Assignment Statements
21
x = 1; // Assign 1 to x;
radius = 1.0; // Assign 1.0 to
a = 'A'; // Assign 'A' to a;

22. Declaring and Initializing in One Step
22
int x = 1;
double d = 1.4;

23. Constants
23
final datatype CONSTANTNAME = VALUE;
final double PI = 3.14159;
final int SIZE = 3;

24. The String Type
24
E.g.: String message = "Welcome to Java";
String Concatenation
// Three strings are concatenated
String message = "Welcome " + "to " + "Java";
// String Chapter is concatenated with number 2
String s = "Chapter" + 2; // s becomes Chapter2
// String Supplement is concatenated with character B
String s1 = "Supplement" + 'B'; // s1 becomes
SupplementB

25. Programming Errors
25
Syntax Errors
Detected by the compiler
Runtime Errors
Causes the program to abort
Logic Errors
Produces incorrect result

26. Converting Strings to Integers
26
use the static parseInt method in the Integer class
as follows:
int intValue =
Integer.parseInt(intString);
where intString is a numeric string such as “123”.

27. Converting Strings to Doubles
27
use the static parseDouble method in the Double
class as follows:
double doubleValue
=Double.parseDouble(doubleString);
where doubleString is a numeric string such as
“123.45”.

28. 28
The Two-way if Statement
if (boolean-expression) {
statement(s)-for-the-true-case;
}
else {
statement(s)-for-the-false-case;
}
true false
Boolean
Expression
Statement(s) for the true case Statement(s) for the false case

29. if...else Example
29
if (radius >= 0) {
area = radius * radius * 3.14159;
System.out.println("The area for the “
+ “circle of radius " + radius +
" is " + area);
}
else {
System.out.println("Negative input");
}

30. Common Errors
30
Adding a semicolon at the end of an if clause is a common
mistake.
if (radius >= 0);
{
area = radius*radius*PI;
System.out.println(
"The area for the circle of
radius " +
radius + " is " + area);
}

31. switch Statements
switch (status) { 31
case 0: compute taxes for single filers;
break;
case 1: compute taxes for married file jointly;
break;
case 2: compute taxes for married file separately;
break;
case 3: compute taxes for head of household;
break;
default: System.out.println("Errors: invalid status");
System.exit(0);
}
