For  Loop  In Java Program

For Loop In Java Program

WHAT IS FOR LOOP IN JAVA?

  • Whenever a set of statements has to be executed multiple times,we will use for statement.

SYNTAX WOULD BE-

for(initialization;condition;updation)

{

//statement block

}

Here,

  • intialization-Contains declaring and/or initialization of one or more variables,that happens once.

  • condition-Must be some Boolean expression,that will be checked immediately after initialization and each time when there is an updation of variables.

  • updation-Contains increment/decrement of variables,that will be executed after executing statement block.

WHY FOR LOOP

  • A program is execellent if we have less codes to run big program.

  • So,For some program which has some codes of iteration we need for loop statements.

  • It is used to reducing coding length.

THINGS I LEARNED

  • I learned to make some program useing forloop statements.

  • Here is one of the simple example of forloop which I learned:

    class For Loop

    {

    public static void main(String args[])

    {

    int x;

    for(x=0;,x<5;x=x+1)

    System.out.println("This is x: "+x);

    }

    }

    Output will be:

    This is x: 0

    This is x: 1

    This is x: 2

    This is x: 3

    This is x: 4

  • like this it helps to minimize the lines we use and creates a excellent program.

CONCLUSION

  • If the number of iteration is fixed, it is recommended to use for loop.

  • Variables declared in the initialization block should be of the same type. Each variable in the initialization must be of the same datatype.

  • Variables declared inside the initialization block are accessible only within the loop.

  • Thats all, use a less number lined program which contains more information in it to be a good programmer.
