Creating the mutable variable in Scala

In this program, we will create a mutable variable using the var keyword. The value of the mutable variable can be changed during the program.

Scala code to create the mutable variable

The source code to create a mutable variable is given below. The given program is compiled and executed on the ubuntu 18.04 operating system successfully.

// Scala program to create mutable variable.

object Sample{  
    def main(args:Array[String]){  
        // Create mutable variable using 'var' keyword.
        var var1 = 108
          
        // Change the value of variable  
        var1 = 111 
        
        println ("Var1: "+var1) 
    }  
}

Output

Var1: 111

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 a mutable variable var1 using the var keyword, which is initialized with 108. Then we changed the value of variable var1 and printed the value of var1 using the println() function on the console screen.
