Error: Could not find or load main class vehicle.Vehicle

Question

I am still at HelloWorld when it comes to my lack of Java skills. I cannot understand this to save my life. I am working on writing an override method? And am just starting out with the code provided from my school before I even start trying to complete the rest and I am already getting errors that I cannot even begin to think of how to correct. Any help at all would be greatly appreciated. I just want this error to go away so I can create some new ones :) Here is the code:

public class Vehicle
public static void main (String [] args)}
{
private boolean moving; // whether or not the vehicle
private double speed; 
private char bearing; 
('N','E','S', or 'W')
public Vehicle(){ // Vehicle class no-arg constructor
    moving = false; // assume not moving
    speed = 0.0; // not moving
    bearing = 'N'; // assume 'N'orth
    System.out.println("Created a vehicle (no-arg)"); 
}
public Vehicle (double initialSpeed) // Vehicle 1-arg constructor
    bearing = 'W';
    speed = initialSpeed;
    if (speed > 0.0)
    {
        moving = true;
    }
    System.out.println("Created a vehicle (1-arg)"); 
public Vehicle (double initialSpeed, char initialBearing) // Vehicle 2-arg constructor
    bearing = initialBearing;
    speed = initialSpeed;
    if (speed > 0.0){
        moving = true;
    }
    System.out.println("Created a vehicle (2-arg)");
public void start(double initialSpeed, char initialBearing){
    moving = true;
    if (initialSpeed >= 5.0 && initialSpeed <= 20.0){
        speed = initialSpeed; // valid expected range
    } else if (initialSpeed >= 0.0 && initialSpeed < 5.0){
        speed = 5.0; // minimum
    } else if (initialSpeed < 0.0){
        speed = 0.0; // assume no movement
        moving = false;
    } else if (initialSpeed > 20.0){
        speed = 20.0; // maximum allowed
    }
    switch(initialBearing){
    case 'N':
        bearing = initialBearing;
        break;
    case 'E':
        bearing = initialBearing;
        break;
    case 'S':
        bearing = initialBearing;
        break;
    case 'W':
        bearing = initialBearing;
    default:
System.out.println("invalid bearing " + 
     initialBearing +
     " set to N"); // additional user notification
     bearing = 'N';
}
public double getSpeed() { // get and return current speed in mph
    return speed;
}
public void setSpeed(double newSpeed){ // set new speed in mph
     speed = newSpeed;
}
    /**
     *
     * @return
     */
public char getBearing(){
    return bearing;
}
public void speedUp(double mphSteps, int numSteps){
    int counter = 0;
    while (counter < numSteps)
    speed += mphSteps;
    System.out.println("counter= " + counter + ", " + 
    this.toString());
    counter++;
}
public String toString(){
    return "From toString(): speed= " + getSpeed() +
    " mph and bearing= " + getBearing();
} 
}
public class Car extends Vehicle{
    private String color;
    private int doors; 
    private double hp; 
    public Car(String carColor, int numDoors, 
    double horsePower, double
    startingSpeed)

System.out.println("Created a car"); 
}
public String getColor()
{
return color;
}
public int getDoors()

}
public double getHp()
{
return hp;
}
public String toString()
{
return "From Car toString(): color= " + getColor() +
" doors= " + getDoors() + 
" hp= " + getHp() +
" speed= " + getSpeed() +
" mph and bearing= " + getBearing();} 
}
public class TestCar2
{
public static void main(String[] args)
{ 
Car myCar2 = new Car("blue", 4, 300., 10.0); 
System.out.println(myCar2.toString());
myCar2.speedUp(5.0, 2); 
}
}

Please Please and thank you for helping!

Answer 1

public class Vehicle

public static void main (String [] args)} // this is totally wrong
     // This not compile at least 
{

Actually parenthesis({}) you are using is totally wrong. Following structure should follow you. I am guessing that you are not using IDE to do coding. I suggest you to use IDE to do code.

public class MyClass{

 public static void main(String[] args){
   // main method
 }
 // some other method

}

Answer 2

Firstly You cannot have two public classes in a single file!!

Secondly you braces are completely unmatching.

public class Vehicle
public static void main (String [] args)}
{

Class has it's own scope and main() function has it's own. So change your code to

public class Vehicle {
public static void main (String [] args) { //your code}
}

your multiple arg constructors don't have proper brackets.

public Vehicle (double initialSpeed) // Vehicle 1-arg constructor
    bearing = 'W';
    speed = initialSpeed;
    if (speed > 0.0)
    {
        moving = true;
    }
    System.out.println("Created a vehicle (1-arg)"); 

change it to

public Vehicle (double initialSpeed) { // Vehicle 1-arg constructor
    bearing = 'W';
    speed = initialSpeed;
    if (speed > 0.0)
    {
        moving = true;
    }
    System.out.println("Created a vehicle (1-arg)"); 
}

lastly your switch statement you need to put break in all cases(except default) change

case 'W':
bearing = initialBearing;

to

case 'W':
bearing = initialBearing;
break;

If you are new to java and learning basics I suggest use an IDE like Eclipse, Netbeans or Intellij IDEA. Google them to find more info.
