Composition

Question

hi guys
i have written a simple program that supposedly illustrates Composition. I am really a novice but i have attempted to learn the stuff. I wrote up the following code, which gives me the following errors on compilation: ( CODE beneath!!)
Car.java:29: ')' expected
System.out.println("one with " + newHonda.color " and has a " +
newHonda.engine_make));
^
Car.java:30: ')' expected
System.out.println( "again it has " + newHonda.country_make " an
d has " + newHonda.doors));
^
2 errors
C:\j2sdk1.4.2_02\bin>javac Car.java
Car.java:29: ')' expected
System.out.println(+ newHonda.color " and has a " + newHonda.eng
ine_make);
^
Car.java:30: ')' expected
System.out.println(+ newHonda.country_make " and has " + newHond
a.doors);
^
2 errors
the code follows:
import java.lang.object;
public class Car
     String color;
     String engine_make;
     String country_make;
     Int doors;
     Engine petrolFired;
     public Car()
     System.out.println("inside constructor Car()");
          color = "Blue";
          engine_make = "Mitsibishi";
          country_make = "japanese";
          doors = 4;
     public static void main(String[] args)
          Car newHonda = new Car();
          Engine.main(args);
     void printCar(Car newHonda)
          System.out.println("the vehicle u wanted to purchase is: ");
          System.out.println(+ newHonda.color " and has a " + newHonda.engine_make);
          System.out.println(+ newHonda.country_make " and has " + newHonda.doors);
          printEngine(petrolFired);
class Engine
     String part1 = "radiator";
     String part2 = "oil pan";
     String part3 = "cylinder head";
     String part4 = "fuel intake assembly";
     public static String newline = System.getProperty("line.separator");
     public static void main(String[] args)
          honda.printCar(honda);
     void printEngine()
          System.out.println("It is: " + petrolFired.part1);
          System.out.println("has an: " + petrolFired.part2);
          System.out.println("an aluminum " + petrolFired.part3);
          System.out.println(" and an improved " + petrolFired.part4);
could somebody debug this program and tell me what i did wrong.Thanks a lot in advance.

All are simple errors.
When you want to use the + operator within System.out.println, be
careful of where you start and end double-quotes (").
It should be like this..
System.out.println("aaaaa" + "bbbbbb" + "ccccccc" + "dddddddd");
Otherwise, the compiler wont know where your String starts and where it ends.
For example:
System.out.println("one with " + newHonda.color " and has a " +
newHonda.engine_make));
SHOULD BE
System.out.println("one with " + newHonda.color + "and has a " +
newHonda.engine_make));
Look carefully in all the other 4 lines, and you will be able to find
the errors.
