Scala – Print the Type of a Variable

In this program, we will get the type of variable using the getClass method and print the result on the console screen.

Scala code to print the type of the variable

The source code to print the type of the variable is given below. The given program is compiled and executed on the ubuntu 18.04 operating system successfully.

// Scala program to print the type 
// of the variable

object Sample{  
    def main(args: Array[String]): Unit = {
        var var1:Char='A'
        var var2:Int=101
        var var3:Float=10.23F
        var var4:String="Hello"
        
        println("Type of var1: "+var1.getClass)
        println("Type of var2: "+var2.getClass)
        println("Type of var3: "+var3.getClass)
        println("Type of var4: "+var4.getClass)
    }  
}

Output

Type of var1: char
Type of var2: int
Type of var3: float
Type of var4: class java.lang.String

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 four variables var1, var2, var3, var4 initialized with some values. After that, we get the type of variables using the getClass method and print the result on the console screen.
