Looping Statement

Looping statements are used when we want to repeat the block of code multiple times as long as a certain conditions remains true.
There are three main looping statements.

1. for loop
2. while loop
3. do while loop

for loop:

The for loop is ideal when the number of executions known in advance.
Syntax:

for(initialization; condition; Increment/decrement)

Example: For printing numbers form 1 ot 7

for(int i = 1; i<=7; i++)
{
System.out.println(i);
}

Output:
1
2
3
4
5
6
7

while lopp:

The while loop used when the number of execution is not fixed and depends on the condition.

Syntax:

initialization;
while(condition)
{
//code to be executed
increment/decrement;
}

Example:

int i = 1;
while(i<=3)
{
System.out.println(i);
i++;
}

Output:
1
2
3
