I have created a single-class Java game in which we need to buy and sell stocks, I have just started Java and am a newbie so need help + this code is not very good.
import java.io.*;
import java.util.Random;
public class stock_holding_game

static Random randomn = new Random();
static BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
public static void main(String[] args)throws IOException
{
double cash = 30.0;
double stocks[] = {0,10,20,40,80,160,320,640};//cost of stocks (there are 7 stocks each with different price)
int mystocks[] = {0,0,0,0,0,0,0,0};
pass("Enter your name");
String name = br.readLine();
pass("Hi "+name);
commandlist();
boolean booleancheck = true;
while(booleancheck)
{
pass("Please enter your command");
String command = br.readLine();
command =" "+command+" ";
char c = command.charAt(2);
switch(c)
{
case'h':
pass("enter the stock ID number");
int s1 = Integer.parseInt(br.readLine());
if(s1>0&&s1<=8)

int add = randomn.nextInt(2);
if(add==0)stocks[s1]=stocks[s1]+t;
else
stocks[s1]=stocks[s1]-t;
pass("Current price: "+stocks[s1]);
}
else

}
break;

I wish to have an applet for this code but I don't know much about applets. I wish to use some buttons instead of typing. I know codes to add buttons but don't know how to use them. Need help on it, all replies would be appreciated.
And yes , also tell how is this game (rate this game), but rate as if a newbie as made it. Now, instead of going on full ask on how to convert it into an applet I wish to ask it in small blocks. First of all how shall I use a button and tell my PC how to proceed?
This is my code:
import java.awt.*;
public class Buttonsuse extends java.applet.Applet
{
Button invest , sell , check ;
public void init()
{
setBackground (Color.white);
setLayout(new FlowLayout (FlowLayout.CENTER,10,10));
invest = new Button("Invest");
sell = new Button("Sell");
check = new Button("Check");
add(invest);
add(sell);
add(check);
}
}
Now, how shall I know and tell the computer that a button is pressed, like if user presses invest button, it prints "you wish to invest".
How shall I do that?
