Question

this code still shows that it still has an syntax error in it can you please fix it. I will put an error message next to the line that is wrong and needs fixed, other than that the other lines seems to be ok.

public static void main()
{
/**
* main method - makes this an executable program.
*/
public static void main("String[]args"); this is the error line that I get and needs fixed
// create a client with placeholder values
system.out.println("Client with default information");
// create a client object using first constructor
Client client1 = new Client();
  
  
// Display information about the client
System.out.println(client1.toString());
  
System.out.println();
System.out.println("Create a client by providing information");
// client last name - Jameson
// client first name - Rebecca
// client age - 32
// client height - 65
// client weight - 130
Client client2 = new Client("Jameson", "Rebecca",
32, 65, 130);
  
// Display information about the client
System.out.println(client2.toString());

// Display the first name
System.out.println("original first name = " +
client2.getFirstName());
  
// set the first name to the value Rachel
client2.setFirstName("Rachel");
  
// Retrieve and dislplay the client first name
System.out.println("new first name = " +
client2.getFirstName());
  
// Display information about the client
System.out.println(client2.toString());

// set their weight to 180
client2.setWeight(180);
  
// Display information about the client
System.out.println(client2.toString());
}

//Use this java code...It may help you

public class Client {
    // client last name
    private String firstName;
// client first name
    private String lastName;
// client age
    private int age;
// client height
    private int height;
// client weight
    private int weight;

    //default Constructor
    public Client()
    {

    }
    //Constructor

    public Client(String firstName, String lastName, int age, int height, int weight) {
        this.firstName = firstName;
        this.lastName = lastName;
        this.age = age;
        this.height = height;
        this.weight = weight;
    }
    //getters setters

    public String getFirstName() {
        return firstName;
    }

    public void setFirstName(String firstName) {
        this.firstName = firstName;
    }

    public String getLastName() {
        return lastName;
    }

    public void setLastName(String lastName) {
        this.lastName = lastName;
    }

    public int getAge() {
        return age;
    }

    public void setAge(int age) {
        this.age = age;
    }

    public int getHeight() {
        return height;
    }

    public void setHeight(int height) {
        this.height = height;
    }

    public int getWeight() {
        return weight;
    }

    public void setWeight(int weight) {
        this.weight = weight;
    }

    @Override
    public String toString() {
        return "Client Name: "+firstName+" "+lastName+" age: "+age+" weight: "+weight+" height: "+height;
    }
}

//==============================================

public class TestClient {
    /**

    public static void main(String[] args)
    {
        // create a client with placeholder values

// Display information about the client
        System.out.println(client1.toString());

        System.out.println();
        System.out.println("Create a client by providing information");
// client last name - Jameson

        Client client2 = new Client("Jameson", "Rebecca",
                32, 65, 130);

// Display information about the client
        System.out.println(client2.toString());

// Display the first name
        System.out.println("original first name = " +
                client2.getFirstName());

// set the first name to the value Rachel
        client2.setFirstName("Rachel");

// Retrieve and dislplay the client first name
        System.out.println("new first name = " +
                client2.getFirstName());

// Display information about the client
        System.out.println(client2.toString());

// set their weight to 180
        client2.setWeight(180);

// Display information about the client
        System.out.println(client2.toString());

    }
