Thread: Help with instantiating a class within a switch statement

Hello everyone, I am not to sure how to go about doing this. What I want to do is instantiate an object from a class and then adjust the values via keyboard input. I think the problem may be that I am trying to adjust the values within switch statements.
Here is the code from the testprogram:

public static void main(String[] args) 
    {
    	String name;
    	String address;
    	int id;
    	double hours;
    	Client x;
    	for(int select=0;select!=3;)
    	{
    	Client num1= new Client("11","111",111,111);
    	Scanner scan = new Scanner(System.in);
    	System.out.println("Please select from the following menu:");
    	System.out.println("1:Add Client");
    	System.out.println("2:Create Invoice");
    	System.out.println("3:Quit");
        select = scan.nextInt();
    	switch(select)
    	{
 
    	case 1:	
    	System.out.println("Please enter the Client's Name: ");
    	name = scan.next();
    	x.setClientName(name);
 
    	System.out.println("Please enter the Client's ID Number: ");
    	id = scan.nextInt();
    	x.setClientId(id);
 
    	System.out.println("Please enter the Client's Address: ");
    	address = scan.next();
    	x.setClientAddress(address);
 
    	System.out.println("Please enter the number of hours worked: ");
    	hours = scan.nextDouble();
    	x.setClientHours(hours);
 
Here is the class that I am using.
 
{
    	clientName=name;
    	clientAddress=address;
    	clientId=id;
    	clientHours=hours;
 
    }
    public void setClientName(String name)
    {
    	clientName=name;
    }
    public void setClientAddress(String address)
    {
    	clientAddress=address;
    }
    public void setClientId(int id)
    {
    	clientId=id;
    }
    public void setClientHours(double hours)
    {
    	clientHours=hours;
    }
 
    public String getClientName()
    {
    	return clientName;
    }
    public String getClientAddress()
    {
    	return clientAddress;
    }
    public int getClientId()
    {
    	return clientId;
    }
    public double getClientHours()
    {
    	return clientHours;
    }

All of the x.sets turn up errors when I compile. Is it possible to Instantiate an object or modify its variables from within switch statements? If it is how would I go about doing that?
Thank You in advance
