If we change the condition used in the preceding
program from (i <= 10) to (i >= 10), the do-while loop
executes the statements only once and stops executing.
However, the condition is false. The output will be
displayed as shown:
The for Loop
The for loop in Java is a control flow Start
statement used to execute a block of
code a specific number of times. It is
Initialisation
particularly useful when the number
of iterations is known beforehand. The
for loop consists of three main parts:
initialisation, condition, and iteration False Conditional
expression. Expression
The syntax of the for loop is as
Increment/Decrement
follows: True
for (initialisation; conditional Body of for loop
expression; increment/decrement)
{
Stop
[statements]
}
In a for loop, the initialisation section sets up a variable when the loop starts. This happens only
once and helps control the loop. It ends with a semicolon. Next, the loop checks a condition to
decide if it should keep running. The loop's instructions keep running as long as the condition
is true. Finally, the loop updates the variable, which controls how many times it repeats.
For example,
public class ForLoop
{
public static void main(String args[])
{
int i;
for(i=1; i<=10; i++)
{
System.out.println("TrackGPT");
}
}
}
The preceding program prints the word ‘TrackGPT’ ten times.
