Running java from the cmd

Trying to run a simple file called Test.java from the cmd. by javac Test.java it appears to run, but nothing is printed to the terminal?

public class Test {
    public static void main(String[] args) {    
            Integer a = 1000, b = 1000;  
            System.out.println(a == b);
            Integer c = 100, d = 100;  
            System.out.println(c == d); 
    }
}
