Java
IDE – Eclipse for Java
Programming Minecraft in Term 3
This term – Basic Java
Java – can be used in other OS's for creating user interfaces

Dungeon Game
–    character (hero)
–    Next week: collision detection routine

…
Today
Setup Eclipse
Intro to Java
…
JavaFX

Read and Write files

Other half of the time
C++

Minecraft
–    minigame

Still need to use Bitbucket

Intro to Java
–    Download Eclipse
Not Microsoft, Apple or Google
Oracle
It is used extensively on Android

Misconception – Java on Windows – vector for viruses

Public
/ public static void main (string[] args) – using console
Finish


// Print test message
System.out.Println(“Test String”);

Important to document

Second Program

int a = 5;
int b = 3;

System.out.Println(a + b);


int sum = 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 10;

System.out.Println(sum);

Loops

(C++)
for (int i = 0; i != 10; ++i) {

}

Java
for (int i = 0; i < 10; ++i) {

}

(0, 10]

for (int i = 0; i < 10; ++i) {
    sum;
}

64 bit int overflow
Formula – sum of 1 to n
n(n + 1)
---------
      2

Third Project

int sum = 0;
int n = 10;
sum = (n * (n + 1)) / 2;

System.out.Println(sum);


ParseInt


int sum = 0;
int n = 10;

if (args.length = 0) {
    n = Integer.parseInt(args[0]);
}

sum = (n * (n + 1))/ 2;
System.out.Println(sum);
System.out.Println(args.length);

System.out.Print(“A”);


for (int x = 0; x < 5; x++) {
    System.out.Print(“A”);
}


for (int x = 0; x < 5; x++) {
    for (int y = 0; y < 5; y ++) {
        System.out.Print(“A”);
    }
}

…

* / + -
% - mod – returns a remainder.

for (int x = 0; x < 5; x++) {
    for (int y = 0; y < 5; y ++) {
        if (y % 2 == 0)
            System.out.Print('A');
        else
            System.out.Print(' ');
    }
    System.out.Println();
}
for (int x = 0; x < 5; x++) {
    for (int y = 0; y < 5; y ++) {
        if (x % 2 == 0) {
            if (y % 2 == 0)
                System.out.Print('A');
            else
                System.out.Print(' ');
        }
        else {
