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

Program/Source Code:

The source code to print the value of variables using the printf() function is given below. The given program is compiled and executed on the ubuntu 18.04 operating system successfully.

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

object Sample{  
    def main(args:Array[String]){  
        var var1:Int     = 123
        var var2:Float   = 3.14F
        var var3:String  = "Hello"
        var var4:Char    = 'A'
          
        printf("Var1: %d\n", var1) 
        printf("Var2: %f\n", var2) 
        printf("Var3: %s\n", var3) 
        printf("Var4: %c\n", var4) 
    }  
}

Output:

Var1: 123
Var2: 3.140000
Var3: Hello
Var4: A

Explanation:

In the above program, we used an object-oriented approach to create the program. Here, we created an object Sample. We defined main() function. The main() function is the entry point for the program.

In the main() function, we created 4 variables var1, var2, var3, var4 that are initialized with 123, 3.14F, "Hello", 'A'. After that, we printed the value of variables using printf() function on the console screen.
