________ uses those methods to perform different tasks.

________ has a similar idea to a loop, but it functions a bit differently.

________ can store primitive or object data types.

An official name that pertains to the world of computers, and coding.

A specific way that someone programs

Comments on the code, they don’t execute anything, but are their to improve the readability of the program for anyone looking at it

enables the computer to understand the code

the languages that computers understand, 0’s and 1’s

the process where the interpreter translates the java code into binary

something is incorrect with the logic behind the code, and it doesn’t give the provided output

this is a type in java used to represent words, or sentences

a piece of code that begins with a backslash that indicates specific characters

this sets values to a variable

The equal sign, =, that assigns a value to something

used to store information to referenced, so that it can be manipulated in the program

+ sign that is used between 2 entities to combine them

the basic types of data used in java

(int) it represents an integer number

(double) it represents a number that can be positive, negative, or zero and can contain decimals, or be fractions

(boolean) a representation of a value that is either true or false

(char) represents any single character that can be represented on the computer anywhere from special characters, letters, numbers, and spaces

the order of operations in java

meaning that java makes you define the variables data type

has a higher precedence than all the other operators, and is used to convert the output that is produced

used to increase the value of a number by 1

used to decrease the value of a number by 1

an entity or data type that we create in java.

they contain instance fields or data that belong to the object and methods that are used to manipulate the data

the order of operations in java

the variable belongs to the class itself, and is initialized only once at the start of the execution

the state of the object doesn’t change since it has been initialized

when using methods of a class, remember the parameters used to call the method need to match the data types of the arguments of the defined method

this is used as a subjective statement, it works hand in hand with conditional statements

used to control the flow of the program, and is based entirely on conditions

(==), checks if something is equal to the other

the truth value, either true or false, for an expression

multiple conditions put together

logical and

logical or

logical not

is equal to

isn’t equal to

used to easily trace values, and their outputs based on the code

used to execute more than one statement based on a condition

used for when programmers want a statement to execute repeatedly

a loop that is found inside a loop

while the condition is true the loop continues to execute, otherwise it exits the loop

the loop isn’t structured correctly, or there is an error in the logic which causes the loop to execute forever

loop

used for when programmers want a statement to execute repeatedly

a loop that is found inside a loop

while the condition is true the loop continues to execute, otherwise it exits the loop

the loop isn’t structured correctly, or there is an error in the logic which causes the loop to execute forever

loop

When a group of statements, such as control structures, are all put together to be referred to this

this is the java programming file that hosts the code

a block of code that, when called, performs specific actions mentioned in it

a class in charge of running other classes

the parent classes of all the java classes

where you tell Java what value type, if any, the method will return

a special method used to initalize objects

a variable that is specific to a certain object

the primitive type in which data should return

the variables listed as a part of the method decleration

a condition that must be true for your method code to work

a condition that is true after the method runs

it belongs to the class rather than to a specific instance

holds many items of the same type

the values that you instantiate in an array

locations that are used to assign to each element found in the array

the way an element in a data structured is accessed, or modified

the default value for every object

since null isn’t a valid object, the code performed on null will result in this

goes in order through each value until the desired one is found

requires an ordered list of values, and every time it cuts the list of values in half until it finds the desired value

the selection sort searches and swaps

uses recursion, this type of sort divides and conquers, the array gets split into 2 pieces and then it is sorted, the 2 sorted pieces than come together to form one sorted list

using a method to call itself

the array is split into a sorted and unsorted part, the values from the unsorted part are placed at the correct position in the sorted part

an array that holds items in a 2 dimensional grid, it’s storing items in rows and columns

holds many items of the same type

the values that you instantiate in an array

locations that are used to assign to each element found in the array

the way an element in a data structured is accessed, or modified
