Java: For Loop

A for loop in java is to iterate a code block, or in simple terms to run through a repetitive loop of some process with conditions, for loop is the best thing to go for in java programming language.

• It has a variable, conditions, and change.
• the variable is declared at the beginning as what it needs to be.
• Condition is given based upon the variable declared in the for loop.
• And lastly, the change is executed inevitable whether let it be increment or decrement it is up to you.

Syntax

for(variable; condition; change)
{
    //code block
}

Example

public class Test
{
    public static void main(String[] args)
    {
        for(int value = 15; value <= 20 ; value++)
        {
            System.out.println(value);
        }
    }
}

Output:
15
16
17
18
19
20

We have used the integer value as the variable and initialized it to 15. So that is where I am gonna begin with and I want the condition of up to 20 numbers from 15. So value <= 20 comes as the condition. Lastly, I wanna increment these numbers one by one during every loop iteration.
