Document Summary
Executes instructions until the conditions are no longer valid while (condition) statements. Variables are created outside the loop and updated within the loop. Executes instructions a certain amount of times (count-controlled) for (initialization; condition; update) statements. Initialization is the value the variable will start with. Condition instructs how long the program will run. Update restarts the variable with a different value. Statements carry out the calculation for another variable. Example: for (int i = 5; i <=10; i++) sum = sum + i; Executes the body of a loop at least once and performs the loop test after the body is executed do statements while (condition); Condition is tested after completing the loop body. Used for input validation: int value; do. System. out. print( enter an integer < 100: ); value = in. nextint(); while (value>= 100); Sentinal values are entered by the user and terminate the program.
