The for Loop
The for loop in Java helps to repeat a Start
set of statements a definite number
of times. It is designed to process the Initialisation
items of any sequence one by one.
The syntax of the 'for' loop is as
follows: False Conditional
for (initialisation; Expression
conditional expression;
Increment/Decrement
increment/decrement) True
{ Body of for loop
[statements]
Stop
}
In a 'for' loop, the initialisation section initialises a variable when the loop starts its execution. This
section executes only once and controls the execution of the 'for' loop. The semicolon symbol
terminates the initialisation section. Next, the conditional expression section is evaluated. This
section contains a test condition. The body of the loop will be executed until the test condition
becomes false. At the end, the increment/decrement section is executed. This controls the
iterations of the 'for' loop.
For example:
public class ForLoop
{
public static void main(String args[])
{
int i;
for(i=1; i<=10; i++)
{
System.out.println("Trackpad");
}
}
}
The preceding program prints the word ‘Trackpad’ ten times.
JUMP STATEMENTS
Sometimes, it is necessary to transfer control out of the loop body before all iterations are
completed. For this purpose, jump statements are used in Java. Java offers two jump statements—
break and continue—which are used within the loops.
