// A simple demonstration of local variable type inference.

public class VarDemo {

public static void main(String[] args) {

// Use type inference to determine the type of the variable named avg. In this case, double is inferred.

var avg = 10.0;

System.out.println("Value of avg: " + avg);

// In the following context, var is not a pre-defined identifier. It is simply a user-defined variable name.

int var = 1;

System.out.println("Value of var: " + var);

// Interestingly, in the following sequence, var is used as both the type of the declaration

// and as a variable name in the initializer.

var k = -var;

System.out.println("Value of k: " + k);

}
