Technology Java and Python Coding

Just don't screw up the script. My friend messed up 2000 lines of code and had to do it all over again because he couldn't find the mistake

 

---===[ JAVA CODING ]===---
​

===========================================================


FUNCTIONS :


Creating

var list = function (friends) {

// Do something here

}





VARIABLES :

byte

short

int - integer - 3, 47, 362

long

double - decimal place 2.3, 587.92

float

char

boolean - true or false

String



Declaring a variable:

<type> <name> = <value>;

E.G :

int 1 = health;

double 1.5 = money;

String name = Tom;



===========================================================


STRINGS :


Strings can also work similar to arrays:

var myName = ‘Tom’

myName[0] //Equals ’T'


===========================================================


LOOPS :


FOR LOOP :

for loop - 3 parts :

for (int i = 0; i < 4; i++) { }

General Syntax :

for (var i = 1; i < 11; i = i + 1) {

/* your code here */;

}

My example :http://i.imgur.com/E23nU4d.png


WHILE LOOP :

while loop - 1 part :

while (!(while == 0)) { }

General Syntax :

var condition = true;

while(condition) {

console.log("Hello!");

// Avoid infinite loops!

condition = false;

}

When the condition equals true, the loop continues to run until it evaluates to false. JavaScript : 1 = true 0 = false


DO WHILE LOOP :

do while loop - all code within :

do {

[code code code]

while (!(input == 0)) }

General Syntax :

// Can be false from the start, since

// do/while runs at least one time

var condition = false;

do {

console.log("I'm printed once!");

} while(condition);


My example (for, while do while loops) :

===========================================================


METHODS :

public : visibility modifier

static : calling it from the main method (must be static)

void : doesn’t need to be returned

int : returns an integer



===========================================================


CLASS DESIGN :

private : Only visible by that class

public : Visible to all classes



===========================================================


BASIC ARRAYS :

String[] = String Array

String[] msgs = new String[5];



Example of declaring an Array :

var myArray = ['hello', 'world’];

myArray[0] //equals “hello"



Remember in Arrays :

First element in array = junkData[0]

Second element in array = junkData[1]



===========================================================


ADVANCED ARRAYS :


TWO DIMENSIONAL ARRAYS :


This basically puts an array inside an array (creates columns, and can be used to create 2D objects)

var twoDimensional = [[1, 1], [1, 1]];

JAGGED ARRAYS :


This allows the creation of different amount of elements within the arrays, such as 3 elements in the first array, 1 element in the next and 2 elements in the third.



Example : var jagged = [[3, 4, 5, 6, 7], [true, false, true]];



HETEROGENEOUS ARRAYS :



These types of arrays manage different types of data. E.G :

var mix = [42, true, "towel"];

===========================================================


SWITCH STATEMENT :


Switch allows you to set a number of options (case(s)) then check an expression to see if it matched any of them. If there's a match, the program will perform the action for the matching case; if there's no match, it can execute a default option



Example :

http://i.imgur.com/M1F6FLc.png



General syntax :

switch (/*Some expression*/) {

case'option1':

// Do something

break;

case'option2':

// Do something else

break;

case'option3':

// Do a third thing

break;

default:

// Do yet another thing

}

===========================================================


LOGICAL OPERATORS :


AND : && :

true && true; // => true

true && false; // => false

false && true; // => false

false && false; // => false

OR : || :

true || true; // => true

true || false; // => true

false || true; // => true

false || false; // => false

NOT : ! :

!true; // => false

!false; // => true


===========================================================


OBJECT :


Put information and functions which use that information in the same place

var myObject = {

key: value,

key: value,

key: value

};

An object is similar to an array, however, it's keys can be variables and strings, not just numbers.



Two ways to create an object :



Object literal notation :

var myObj = {

type: 'fancy',

disposition: 'sunny'

};



var emptyObj = {};

Object Constructor :

var myObj = new Object();

Adding keys to an Object constructor is done by :

myObj["name"] = "Charlie";

myObj.name = "Charlie";

 

That's actually pretty nice! I remember learning that in javascript :V.

Right when I saw Python I didn't really like, I never took any lessons on it. I'm intermediate in Java having learned from thenewboston. However, I CANNOT tell you how horrible I am at bukkit. I'm good at Javadon't understand how I can't handle bukkit which is way easier .-. . If I made a server all I would probably do is copy codes and change the output of it so it looks 'official' .

 

All I can say is check your script every 5 lines or so, I am not that good at coding, but I know that putting a " when it should be a ' can be fatal

 

Everyone gets it right away, I guess I'm lacking that sense... well in all, I'm a waffle am I not?

 

A few pointers:
0x00029FAB
0x0091BC6D
0x00C6DD49

 

and whats why you use a good api so stupid **** like that doesnt happen :V
