Scanner

sytax for declaring dcanner and create scanner that reads from system in

Scanner keyboard = new Scanner (system.in)

what happens without perantheses

according to the rules of precedence

to initialize the scanner class we have to

declare / define a scanner object/ variable named "Keyboard"

when one of the operands a floating point type and the other is an int what is the result

floating point type

to import sanner

import.java.util.Scanner;

scanner is provided by

operands, operators, parentheses

two types of increment and decrement

prefix and postfix and are not the same thing

the combination of an operator with the = used for assigment form is called a (combing assigment and arithmetic operators)

shorthand assigment opearator ex: amount = amount + 5; = amount +=5;

when unary operators have equal precedence what happense

the operator on the right acts before the left

when dividing by an int the result is
