Repeating Structures

Do While Loops

Do While Loop• While loops have a test condition before the loop

– This means that java will test the condition before entering the loop

– It is possible that the instruction inside a while loop will be skipped entirely

• do-while loops are similar, but have the test condition at the end of the loop– This allows the instructions in the loop to be executed at least

once before the condition is tested– Since the condition variable is tested after at least one iteration of

the loop, the initialization before the loop is not always necessary• You can actually set the test variable within the loop!• However, if you want your test variable to have an initial variable,

make sure you set it OUTSIDE the loop. Or else you will continue set the variable to this initial condition every time the loop is iterated
