5 basic instuctions in programming

input, output, math, decisions, repetition

why we create methods in java

to group and oranginze code

best practices of writing methods

incremental development and temporary variable

what is debugging? Ways to debug a code.

Checking for bugs and debug by coding in increments

describe ways to do incremental development?

write code and test it

what are data types?

value that a data type stores

identify data types?

int, boolean, double, char, string, array

What are escape sequences? provide samples

Represent special characters inside a string

what are variables?

named storage location to store data

Value

the actual information

parameters

method that stores its arguments

arguments

The actual values or expressions passed into a method during a call. These values initialize the method's parameters and must match the specified type and order

2 types of packages

standard and user defined

what is the scanner class used for?

user inputs

what methods do you use with the scanner class to get user input?

next int, next double, next line

identify rational operators

==, <, >, <=, >=

logical operators

&&,||,!

How to do conditional with strings

if (Varname.equals(“fruit”))

Reference to an array

arrayB = arrayA

Copy of an Array

arrayB = Arrays.copyOf(arrayA) ORRRR a for loop

while loop

checks condition first

for loop

does evreything in one statement

do while loop

does evreything and then checks it
