Scala Program To Create Different Types Of Variable

How to create different types of variables in scala programming? In this post, we are especially going to see how you can create the different variables and how to assign values to each of them.

Scala Program To Create Different Types Of Variable

In this program, we took 4 different data types. We declared each variable for data types and then assigned a value to it.

object divineseo{
    def main(args:Array[String]){  
        var b:Boolean = false
        var i:Int = 123456789
        var f:Float = 9.19999F
        var s:String = "Hello World"
        var c:Char = 'A'
          
        println ("Boolean: "+b) 
        println ("Int: "+i) 
        println ("Float: "+f) 
        println ("String: "+s) 
        println ("Char: " +c)
    }  
}

Output

Boolean: false
Int: 123456789
Float: 9.19999
String: Hello World

Note: The first letter of any data type should be in a capital letter otherwise it produces an error

error: not found: type int

Scala program to print the value of variables using printf() function

As we all are familiar with printf(), it is used in C programming to print the statement or value or result in the console screen. Now we are going to use printf() function to print the values in the console screen in scala programming.

object divineseo{
    def main(args:Array[String]){  
        var b:Boolean = false
        var i:Int = 123456789
        var f:Float = 9.19999F
        var s:String = "Hello World"
        var c:Char = 'A'
        
        printf ("Boolean is %b\n",b)
        printf ("Integer is %d\n", i) 
        printf ("Float is %f\n", f) 
        printf ("String is %s\n", s) 
        printf ("Char is %c\n", c)
    }  
}

It is very much similar to C programming because we are using the same line of code if we wish to print something in c language. But in scala we do not use “;” to terminate the line.
