Question

我开始学习编程，我在java中编写了一个简单的代码，

是一场比赛，每个参赛者都会咬一口苹果，所以被咬的参赛者更有重量！

但!!我需要用java方法，函数添加所有代码......你知道

请运行代码，让您了解更多

任何帮助？非常感谢！

import java.io.*;

   class reality_show_methods{

public static void main(String[] args)throws java.io.IOException{

    BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
    PrintStream out = System.out;

    // VARIABLES
    int     counterParticipants = 1, numPart, numBoc;

    double  weightBoc, weightBocTotalMayor = 0;

    String  namePart, nameParticipantWinner = "";                                                                                                                     

    // SETUP
    out.print("Number of Participants ......................... ");
    numPart = Integer.parseInt(in.readLine());

    out.print("Number of Participants Bites: ....... ");
    numBoc = Integer.parseInt(in.readLine());

    // START
    while (counterParticipants <= numPart) {

        out.print("\nParticipant Name #" + counterParticipants + " ...................... ");
        namePart = in.readLine();

        int countBoc = 1;                                                     
        double weightBocTotal = 0;                                               

        while (countBoc <= numBoc) {

            out.print("Bite weight #" + countBoc + " of the Participant " + namePart + ": ");
            weightBoc = Double.parseDouble(in.readLine());

            weightBocTotal = weightBocTotal + weightBoc;

            countBoc++;
        }

        if (weightBocTotalMayor < weightBocTotal) {                                
            weightBocTotalMayor = weightBocTotal;
            nameParticipantWinner = namePart;
    }

    counterParticipants++;
}

// SHOW WINNER
out.println("\nParticipant Winner: ................... " + nameParticipantWinner + " with Total Weight: " + weightBocTotalMayor);

} 

     }

Answer 1

你的意思是：

public static void myFunction()
{
    // blah blah
}
