3.4.4 Iterative Statements
Sometimes, we may require to repeat certain lines of the program according to the logic or need of the program. A
programming language like Java allows the statements to repeat a specified number of times. This repetitive flow of
control in a program is called a Loop and the repetitive statements are called iterative statements. The loop is used to
execute a certain number of lines again and again to get the desired result. There are three types of for loops in Java.
Which are as follows:
for loop
while loop
do-while loop
3.4.5 The for Loop
The for loop is the most widely used Java loop construct. The syntax of the Java for statement is as below:
for (counter=initial_value; test_condition;change counter)
{
statements
}
