Java Levels 3-4

Question 1

loops

Answer 1

allow a chunk of code to be repeated over & over, depending on a condition

Question 2

while

Answer 2

int x;

x = 0;

while(x < 10) { condition

System.out.println("Hello World!");

x++;

}

will repeat everything inside the curly braces of the loop as long as the condition inside the parentheses is true

Question 3

x++

Answer 3

short for x = x + 1

Question 4

incrementing

Answer 4

adding 1 to the value stored in the variable

Question 5

increment operator

Answer 5

++ in x++

Question 6

for

Answer 6

almost identical to while, but syntax diff

public class TheCount
 {
     public static void main()
     {
         for(int count = 1; count \<= 100; count++) {
             System.out.println(count + "! A-HA-HA!");
         }
     }
 }

for(initialization; condition; statement)

Question 7

initiliazition

Answer 7

The initialization section of a for loop is done only one time before the loop starts. Most programmers use this section to declare their counting variable and set up its starting value.

Question 8

counting variable/count

Answer 8

integer

set to a starting #

Question 9

sentinel loop

Answer 9

waits for a condition to be true before stopping but doesn’t involve a looping variable

waiting for user to type something before it exits
