1 Today s topics Java programs Parsing Java Programming Notes from Tammy Bailey Reading Great Ideas, Chapter 3 & 4 Java programs are created as text files using a text editor (like emacs) Save to disk with.java file extension HelloWorld.java The file contains characters (stored as bytes) file can be printed, displayed on monitor, or edited file cannot be directly executed (run) by the computer system Java must first translate the program into bytecodes before it can be run CompSci CompSci Bytecodes Java Virtual Machine (JVM) Java bytecode machine instruction for the Java processor Java compiler javac translates the source program into bytecodes Bytecode file has same name as the source program with a.class file extension: HelloWorld.class HelloWorld.java javac HelloWorld.class Bytecode (class) file will contain exactly the same bytecodes no matter what computer system is used Bytecode file is executed by a Java bytecode interpreter processor specific executable program Each type of computer system has its own Java interpreter that can run on that system Any computer system can execute Java bytecode programs if it has a Java interpreter Computers with Java interpreters are called Java Virtual Machines a computer with a Java processor that can run Java bytecodes source program Java compiler Java bytecodes CompSci CompSci

2 Java applets Data types An applet is a Java bytecode program that runs on a Web browser Most newer Web browsers have Java interpreters Web pages on the Internet contain instructions that send Java bytecodes to your computer Web browser runs the Java applet with its built-in interpreter Computer memory stores arbitrary bit patterns Meaning of a bit pattern depends on its use Pattern used for a particular string of bits is a data type values are any kind of data a computer can process all values are represented using some data type Example: What does the following pattern of 16 bits represent? No way to know without more information If data type is short (a Java type) it represents 103 CompSci CompSci Java data types Primitive data types Primitive types of data that are so fundamental ways to represent them are built into Java Object built-in or user-defined All primitive values belong to one of eight primitive types byte short int long float double char boolean Primitive data types use a fixed number of bytes four of these types designate different sizes of bounded integers: byte, short, int, long A programmer can not create new primitive data types Any data type you invent will be a type of object Most commonly used types in practice: int, boolean, and double CompSci CompSci

3 Java primitive data types Basic operators Primitive Type Description Range Operator Java Description byte 8-bit integer -128 to 127 Assignment = assigns rhs to lhs short int long 16-bit integer 32-bit integer 64-bit integer to to to Arithmetic Unary +,-,*,/,% -,++,-- addition, subtraction, multiplication, division, remainder negative, auto increment, auto decrement float 32-bit floating point to Equality ==,!= equals to, not equals to double char 64-bit floating point Unicode character to Relational <,<=,>,>= less than, less than or equals to, greater than, greater than or equals to boolean Boolean variable false and true CompSci Logical &&,,! AND, OR, NOT CompSci Variable declaration Examples Declaration type <variable-name>; Declaration + initialization: type <variable-name> = <value>; Variable names any combination of letters, numbers, and the underscore character may not start with number may not be reserved word e.g. int, return, if, for, while may not be same as a subroutine name case-sensitive (num and Num are different) int x, y, z; int sum = 0; float f; double pi = 3.14; char first = T, middle = L, last = B ; char first = T ; char middle = L ; char last = B ; CompSci CompSci

4 Operator precedence When in doubt, use parentheses Evaluate a + b * c multiplication first? a + (b * c) addition first? (a + b) * c Java solves this problem by assigning priorities to operators (operator precedence) operators with high priority are evaluated before operators with low priority operators with equal priority are evaluated left to right Operator priority (highest to lowest) 1. ( ) 2. * / % = a + b * c = a + (b * c) because * has higher priority than + To perform the + operation first we need to use parentheses (a + b) * c If in any doubt use extra parentheses to ensure the correct order of evaluation parentheses are free! cause no extra work for the computer only make it easier for you to work out what is happening CompSci CompSci Examples Java adheres to traditional order of operations * and / have higher priority than + and int x = * 6; (x = 33) int y = (3 + 5) * 6; (y = 48) Parentheses are free, use them liberally int z = ((3 + 5) * (6)); (z = 48) Equal priority operations are evaluated left-to-right in the absence of parentheses int w = 3 * 4 / 2 * 6; (w = 36) int x = 3 * 4 / (2 * 6); (x = 1) int y = 3 * * 6; (y = 24) int z = 3 * (4 + 2) * 6; (z = 108) Syntax and semantics Addition, subtraction: + and, int and double int x = 21+4; (x = 25) double y = ; (y = 12.1) Multiplication: *, int and double int x = 21*4; (x = 84) double y = 14.1*2.5; (y = 35.25) Division: /, different for int and double int x = 21/4; (x = 5) double y = 21/4; (y = 5.0) double y = 21/4.0; (y = 5.25) Modulus: %, only for int int x = 21%4; (x = 1) CompSci CompSci

5 Automatic type conversion Mixed type expressions are converted to higher compatible types If all operands are of type int then result is type int If any operand is of type double then result is of type double Cannot convert to a lower type Conversion may result in loss of precision Example: Convert Fahrenheit to Celsius double F=41.0; double C=(F-32.0)*(5/9); Question: What is the value of C? a) 5 b) 0.0 c) 9.0 d) 5.0 e) 9 CompSci More expressions int g = ; What is the value of g? a. 0 b. 12 c. 14 d e. error int n = 1 2 * 3 (4 + 5); What is the value of n? int x = 8 * ( ) % (4 + 3 / 2) 1; What is the value of x? a. -1 b. 0 c. 2 d. 3 e. none of the above CompSci Syntax errors Logic errors The following Java subroutine computes the inclusive sum between two integers. Find all the syntax errors. The computer will do precisely what you say even though it may not be what you want What is wrong with this code? int sumbetween( x, y ) { int z = x; Int sum = 1; while( z <= y ){ sum = sum*z; z++ } int sumbetween( int x, int y ) { int z = x; int sum = 1; while( z <= y ) sum = sum*z; z++; CompSci CompSci } }

6 Java objects Real-world objects Java is an object-oriented programming language use objects to define both the data type and the operations that can be applied to the data Objects have attributes and functionality attributes describe the state of the object the functionality of an object is the set of actions the object can perform In Java, we define an object s attributes using variables and its functionality using methods Suppose we want to describe a car in terms of its attributes and functionality Attributes: int year; int mileage; String make; String model; boolean manual_transmission; Methods: void brake() int getmileage() boolean needsgas() void shift(int gear) CompSci CompSci Java classes Java String class Java objects are created using classes Encapsulation combining elements to create a new entity A class encapsulates the variables and methods that define an object Instantiation the act of creating an object objects are called class instances Java provides many predefined classes You can also define your own classes The String class represents character strings String first = Tammy ; String last = Bailey ; Strings can be concatenated (added together) using the concatenation operator + String fullname = first + + last; Testing for equality: first.equals( Tammy ); /* returns true */ first.equals( Amy ); /* returns false */ CompSci CompSci
