Java Classes and Objects 1,139 Java is an object-oriented programming language.Everything in Java is associated with classes and objects,along with its attributes and methods.For example: in real life,a car is an object.The car has attributes,such as weight and color,and methods,such as...  |
Java Scope 1,146 In Java,variables are only accessible inside the region they are created.This is called scope.Method Scope.Variables declared directly inside a method are available anywhere in the method following the line of code in which they were declared:Block Scope.A... |
Java Methods 1,130 A method is a block of code which only runs when it is called.You can pass data,known as parameters,into a method.Methods are used to perform certain actions,and they are also known as functions.Why use methods? To reuse code: define the code once,and use ... |
Java Arrays 1,363 Arrays are used to store multiple values in a single variable,instead of declaring separate variables for each value.To declare an array,define the variable type with square brackets:We have now declared a variable that holds an array of strings.To insert ...  |
Java If ... Else 733 You already know that Java supports the usual logical conditions from mathematics::Less than: a < b,Less than or equal to: a b,Greater than or equal to: a >= b,Equal to a == b,Not Equal to: a != b.You can use these conditions to perform different actions f... |
Java Variables 506 Variables are containers for storing data values.In Java,there are different types of variables,for example::String - stores text,such as "Hello".String values are surrounded by double quotes,int - stores integers (whole numbers),without decimals,such as 1... |
Python Modules 728 What is a Module?.Consider a module to be the same as a code library.A file containing a set of functions you want to include in your application.Create a Module.To create a module just save the code you want in a file with the file extension .py:Use a Mod... |
Python Scope 720 A variable is only available from inside the region it is created.This is called scope.Local Scope.A variable created inside a function belongs to the local scope of that function,and can only be used inside that function.Function Inside Function.As explai... |
Python Classes/Objects 590 Python is object-oriented.In Python,most things are objects with properties and methods.Class is an object constructor or "blueprint" for creating objects.Create a Class.To create a class,use the keyword class: .Create Object.Now we can use the class named... |
Python While Loops/For Loops 648 The while Loop.With the while loop we can execute a set of statements as long as a condition is true.The while loop requires relevant variables to be ready,in this example we need to define an indexing variable,i,which we set to 1. .The break Statement.Wit...  |
Python Conditions and If statements 542 Python supports the usual logical conditions from mathematics::Equals: a == b,Not Equals: a != b,Less than: a < b,Less than or equal to: a b,Greater than or equal to: a >= b.These conditions can be used in several ways,most commonly in "if statements" and ...  |
Python Tuples 726 Tuples are used to store multiple items in a single variable.Tuple is one of 4 built-in data types in Python used to store collections of data,the other 3 are List,Set,and Dictionary,all with different qualities and usage.A tuple is a collection which is o...  |
Python String Operations 113 You can return a range of characters by using the slice syntax.Specify the start index and the end index,separated by a colon,to return a part of the string.Slice From the Start.By leaving out the start index,the range will start at the first character:Sli... |
Python Data Types 794 In programming,data type is an important concept.Variables can store data of different types,and different types can do different things.Python has the following data types built-in by default,in these categories:Text Type:str.Numeric Types:int,float,compl... |
