1 Crash Course in Java Based on notes from D. Hollinger Based in part on notes from J.J. Johns also: Java in a Nutshell Java Network Programming and Distributed Computing Netprog 2002 Java Intro 1
2 What is Java? A programming language. As defined by Gosling, Joy, and Steele in the Java Language Specification A platform A virtual machine (JVM) definition. Runtime environments in diverse hardware. A class library Standard APIs for GUI, data storage, processing, I/O, and networking. Netprog 2002 Java Intro 2
3 Why Java? Network Programming in Java is very different than in C/C++ much more language support error handling no pointers! (garbage collection) threads are part of the language. some support for common application level protocols (HTTP). dynamic class loading and secure sandbox execution for remote code. source code and bytecode-level portability. Netprog 2002 Java Intro 3
4 Java notes for C++ programmers Everything is an object. Every object inherits from java.lang.object No code outside of class definition! No global variables. Single inheritance an additional kind of inheritance: interfaces All classes are defined in.java files one top level public class per file Netprog 2002 Java Intro 4
5 More for C++ folks Syntax is similar (control structures are very similar). Primitive data types similar bool is not an int. To print to stdout: System.out.println(); Netprog 2002 Java Intro 5
6 First Program public class HelloWorld { } public static void main(string args[]) { } System.out.println("Hello World"); Netprog 2002 Java Intro 6
7 Compiling and Running HelloWorld.java javac HelloWorld.java source code run compile java HelloWorld HelloWorld.class bytecode Netprog 2002 Java Intro 7
8 Java bytecode and interpreter bytecode is an intermediate representation of the program (class). The Java interpreter starts up a new Virtual Machine. The VM starts executing the users class by running it s main() method. Netprog 2002 Java Intro 8
9 PATH and CLASSPATH The java_home/bin directory is in your $PATH If you are using any classes outside the java or javax package, their locations are included in your $CLASSPATH Netprog 2002 Java Intro 9
10 The Language Data types Operators Control Structures Classes and Objects Packages Netprog 2002 Java Intro 10
11 Java Data Types Primitive Data Types: not an int! boolean true or false char unicode! (16 bits) byte signed 8 bit integer short signed 16 bit integer int signed 32 bit integer long signed 64 bit integer float,double IEEE 754 floating point Netprog 2002 Java Intro 11
12 Other Data Types Reference types (composite) classes arrays strings are supported by a built-in class named String string literals are supported by the language (as a special case). Netprog 2002 Java Intro 12
13 Type Conversions conversion between integer types and floating point types. this includes char No automatic conversion from or to the type boolean! You can force conversions with a cast same syntax as C/C++. int i = (int) 1.345; Netprog 2002 Java Intro 13
14 Operators Assignment: =, +=, -=, *=, Numeric: +, -, *, /, %, ++, --, Relational: ==.!=, <, >, <=, >=, Boolean: &&,,! Bitwise: &,, ^, ~, <<, >>, Just like C/C++! Netprog 2002 Java Intro 14
15 Control Structures More of what you expect: conditional: if, if else, switch loop: while, for, do break and continue (but a little different than with C/C++). Netprog 2002 Java Intro 15
16 Exceptions Terminology: throw an exception: signal that some condition (possibly an error) has occurred. catch an exception: deal with the error (or whatever). In Java, exception handling is necessary (forced by the compiler)! Netprog 2002 Java Intro 16
17 Try/Catch/Finally try { // code that can throw an exception } catch (ExceptionType1 e1) { // code to handle the exception } catch (ExceptionType2 e2) { // code to handle the exception } catch (Exception e) { // code to handle other exceptions } finally { // code to run after try or any catch } Netprog 2002 Java Intro 17
18 Exception Handling Exceptions take care of handling errors instead of returning an error, some method calls will throw an exception. Can be dealt with at any point in the method invocation stack. Forces the programmer to be aware of what errors can occur and to deal with them. Netprog 2002 Java Intro 18
19 Concurrent Programming Java is multithreaded! threads are easy to use. Two ways to create new threads: Extend java.lang.thread Overwrite run() method. Implement Runnable interface Include a run() method in your class. Starting a thread new MyThread().start(); new Thread(runnable).start(); Netprog 2002 Java Intro 19
20 The synchronized Statement Java is multithreaded! threads are easy to use. Instead of mutex, use synchronized: synchronized ( object ) { } // critical code here Netprog 2002 Java Intro 20
21 synchronized as a modifier You can also declare a method as synchronized: synchronized int blah(string x) { } // blah blah blah Netprog 2002 Java Intro 21
22 Classes and Objects All Java statements appear within methods, and all methods are defined within classes. Java classes are very similar to C++ classes (same concepts). Instead of a standard library, Java provides a lot of Class implementations. Netprog 2002 Java Intro 22
23 Defining a Class One top level public class per.java file. typically end up with many.java files for a single program. One (at least) has a static public main() method. Class name must match the file name! compiler/interpreter use class names to figure out what file name is. Netprog 2002 Java Intro 23
24 Sample Class (from Java in a Nutshell) public class Point { public double x,y; public Point(double x, double y) { this.x = x; this.y=y; } public double distancefromorigin(){ return Math.sqrt(x*x+y*y); } } Netprog 2002 Java Intro 24
25 Objects and new You can declare a variable that can hold an object: Point p; but this doesn t create the object! You have to use new: Point p = new Point(3.1,2.4); there are other ways to create objects Netprog 2002 Java Intro 25
26 Using objects Just like C++: object.method() object.field BUT, never like this (no pointers!) object->method() object->field Netprog 2002 Java Intro 26
27 Strings are special You can initialize Strings like this: String blah = "I am a literal "; Or this ( + String operator): String foo = "I love " + "RPI"; Netprog 2002 Java Intro 27
28 Arrays Arrays are supported as a second kind of reference type (objects are the other reference type). Although the way the language supports arrays is different than with C++, much of the syntax is compatible. however, creating an array requires new Netprog 2002 Java Intro 28
29 Array Examples int x[] = new int[1000]; byte[] buff = new byte[256]; float[][] mvals = new float[10][10]; Netprog 2002 Java Intro 29
30 Notes on Arrays index starts at 0. arrays can t shrink or grow. e.g., use Vector instead. each element is initialized. array bounds checking (no overflow!) ArrayIndexOutOfBoundsException Arrays have a.length Netprog 2002 Java Intro 30
31 Array Example Code int[] values; int total=0; for (int i=0;i<value.length;i++) { } total += values[i]; Netprog 2002 Java Intro 31
32 Array Literals You can use array literals like C/C++: int[] foo = {1,2,3,4,5}; String[] names = { Joe, Sam }; Netprog 2002 Java Intro 32
33 Reference Types Objects and Arrays are reference types Primitive types are stored as values. Reference type variables are stored as references (pointers that we can t mess with). There are significant differences! Netprog 2002 Java Intro 33
34 Primitive vs. Reference Types int x=3; int y=x; There are two copies of the value 3 in memory Point p = new Point(2.3,4.2); Point t = p; There is only one Point object in memory! Point p = new Point(2.3,4.2); Point t = new Point(2.3,4.2); Netprog 2002 Java Intro 34
35 Passing arguments to methods Primitive types: the method gets a copy of the value. Changes won t show up in the caller. Reference types: the method gets a copy of the reference, the method accesses the same object! Netprog 2002 Java Intro 35
36 Example int sum(int x, int y) { x=x+y; return x; } void increment(int[] a) { for (int i=0;i<a.length;i++) { a[i]++; } } Netprog 2002 Java Intro 36
37 Comparing Reference Types Comparison using == means: are the references the same? (do they refer to the same object?) Sometimes you just want to know if two objects/arrays are identical copies. use the.equals() method you need to write this for your own classes! Netprog 2002 Java Intro 37
38 Packages You can organize a bunch of classes and interfaces into a package. defines a namespace that contains all the classes. You need to use some java packages in your programs java.lang java.io, java.util Netprog 2002 Java Intro 38
39 Importing classes and packages Instead of #include, you use import You don t have to import anything, but then you need to know the complete name (not just the class, the package). if you import java.io.file you can use File objects. If not you need to use java.io.file objects. Netprog 2002 Java Intro 39
40 Sample Code Sum.java: reads command line args, converts to integer, sums them up and prints the result. Sum1.java: Same idea, this one creates a Sum1 object, the constructor then does the work (instead of main). Netprog 2002 Java Intro 40
41 More Samples Multiple Public classes: need a file for each class. Tell the compiler to compile the class with main(). automatically finds and compiles needed classes. Circle.java, CircleTest.java, Point.java, Threads.java, ExceptionTest.java Netprog 2002 Java Intro 41
