Working with X++ 

Static: Static methods are methods that are called on the class itself, means an instance of class is not required to call this methods. 

Void: This datatype show that the return value is null.

Main: This is the method from where the execution of code get start. A class in order to execute on its own, should have a main method.

Display messages - 

•   info("Amount has been credited");
•   warning("Insufficient funds");
•   error("Transaction is aborted");

First Program - 

static void FirstJob(Args _args)
{
      str information;
      information = "Hello..Let’s learn ax"; 
      info(information);
}

Addition of Number - 

static void Additions(Args _args)
{
      int a = 10;
      int b = 20;
      int c;

      c = a + b;

       // conversion functions - int2str, str2Int

        info(int2str(c));

        // concatenation

        info("The result after addition is " + int2str(c));
}

If Else condition

static void IfElseExample(Args _args)
{

         AmountMST amount = 150;   

         if (amount > 200)

    {

        info("You can watch a movie");

    }

    else

        throw error("Insufficient money");

    } 

    info("I have seen the show.Movie is good");

}

If ElseIf else -

static void ifLoop(Args _args)

{

        int age = 10;

        if (age <= 2)
        {
                info("Still a baby");
         }
         else if (age >2 && age <=19)
         {
                info("Teenage");
         }
          else if (age >=20 && age <=45)
         {
                info("MIDDLE AGE");
         }
        else
        {
                info("Old age");

        }

}

 

Loops - (For loop & While loop)

static void LoopsInAX(Args _args)
{ 

    int i = 1;   

   //For loop

    for (i = 1; i <=4 ; i++)

    {

        info("Eating");

    }

 

//While Loops

    i = 1;   

    while (i <=4)

    {

        info("Eating");

        i++;

             }

}

 

Switch Case - 

static void swtichCaseExample(Args _args)

{

    Gender genderType = Gender::Male;   

    switch(genderType)

    {

        case Gender::Male  : info("I am male"); break;

        case Gender::Female  : info("I am female"); break;

        case Gender::NonSpecific  : info("I am Nonspe"); break;

        case Gender::Unknown  : info("I am unknown"); break;

        default: info("Incorrect value");
    }

}

 

Break and Continue 
static void breakAndContinue(Args _args)

{

    int i = 1;  

    for (i = 1; i <= 10; i++)

    {
        if (i == 5 )

            break; // continue;

        info("Hello" + int2str(i));

    }

}

String formatting - 

static void strfmtFunction(Args _args)

{

    // infolog can only print string datatype

    // if you want to print different data types in an infolog.
        You need to convert all the datatypes first in to string and then print

    //Example : I AM RAHU. MY AGE IS 20. MY SAL IS 5000.00

   

    info(strFmt("I AM RAHU. MY AGE IS %1. MY SAL IS %2", 20, 5000.00));
