Review: Repetition structures
while() loop
◮ while (condition) { action(s) }
- Example:
int a = 10; while(a < 10) { System.out.print(a+" "); a++; }
◮ Output: 3/7

SLIDE 10
For repetition structure
for ( init; testForFinal; modification ) { actionStatement(s);}
◮ The init section should create and initialize your loop control
variable.
◮ The testForFinal section should be a Boolean expression to
test for the final value.
◮ The modification section should be an arithmetic statement
(usually a ++ or – action) to modify the loop control variable.

For loop
public class ForLoop { public static void main ( String args[] ) { for ( int counter = 1; counter <= 10; counter++) System.out.println ( counter ); } }
