while loop

• an iterative structure that loops until a conditional statement is no longer true

• a loop that iterates, or repeats, for a set number of times

• makes a decision based on input

• creates spaces in memory that holds elements all of the same types

for loop

• a loop that iterates, or repeats, until a condition is met

• an iterative structure that loops for a set number of times

• makes a decision based on input

• creates spaces in memory that holds elements all of the same types

if - else statement

• a conditional statement that works great for a range of values like if age > 65

• a decision structure that works great for a bunch of specific values like menu items

• trys protected code, catches exceptions

• creates spaces in memory that holds elements all of the same types

array

• a loop that iterates, or repeats, until a condition is met

• creates spaces in memory that hold elements of the same type, you find them by calling on their index, they CAN change size

• creates spaces in memory where you need the key-value pair to find them

• creates spaces in memory that hold elements of the same type, you find them by calling on their index, they CANNOT change size

type of variables a function wants, found in the parenthesis

public static int countDown( int num ){

• parameters
• arguments

the information sent in parenthesis

countDown( 12 );

• parameter

• ARGUMENT!!!!

• int

• choose argument, an argument is sent to a function in parenthesis

Which TWO are conditional structures?

• if-else

• for loop

• switch

• while loop

A bit is

• An agreed upon set of rules or guidelines for doing things.

• A single unit of information, it can be a 1 or a 0 and represents an electrical signal on a wire that is on or off.

• Number of bits that are conveyed or processed per unit of time

• Time it takes for a bit to travel from its sender to its receiver

int i = 1;

while( i < 5){

i++;

System.out.print(i);

}

What is the last value of i?

• 5

• 2GB

• 4

• 6

int a = 5, b = 3, c = 11;

if( a == b || a < c ) {

System.out.println( “ fresh ” );

} else {

System.out.println( “ cut ” );

}

• fresh

• cut

• nothing

• fresh

  cut
