public class TestConstructor {

     private int in;

     private String str;

     public TestConstructor( int in, String str) {

            this. in = in;

            this. str = str;

     };

     public static void main(String[] args) {

           TestConstructor tc = new TestConstructor(2, "abc");

           System. out.println( tc. in+ "\n"+ tc. str);

     }

}
