I need the rest of code in Main class. Anyone can help me??

public class Gambler {

public static void main(String[] args) {
int stake = Integer.parseInt(args[0]); // gambler's stating bankroll
int goal = Integer.parseInt(args[1]); // gambler's desired bankroll
int T = Integer.parseInt(args[2]); // number of trials to perform

int bets = 0; // total number of bets made
int wins = 0; // total number of games won

// repeat N times
for (int t = 0; t < T; t++) {

// do one gambler's ruin simulation
int cash = stake;
while (cash > 0 && cash < goal) {
bets++;
if (Math.random() < 0.5) cash++; // win \$1
else cash--; // lose \$1
}
if (cash == goal) wins++; // did gambler go achieve desired goal?
}

// print results
System.out.println(wins + " wins of " + T);
System.out.println("Percent of games won = " + 100.0 * wins / T);
System.out.println("Avg # bets = " + 1.0 * bets / T);
}

}
