如何用ACM库（ConsoleProgram）编写我的Java程序？ [英] How to write my Java program with the ACM library (ConsoleProgram)?

问题描述

这是我的代码示例：

  public static void main（String [] args）{
 int q; 
 int p; 
 int最大; 
 int最小; 
 
扫描仪输入=新的扫描仪（System.in）; 
 System.out.println（输入数字列表：）; 
 String input2 = input.nextLine（）; 
 
 String [] numbers = input2.split（）; 
 
 int [] result = new int [numbers.length]; （p = 0; p< numbers.length; p ++）
 {
 result [p] = Integer.parseInt（numbers [p]）; （q = 0; q  
} 
 
为（q = 0; q  System.out.print（）; 
 System.out.println（result [q]）; 
} 
 
 System.out.println（最大数字：+最大数字（结果））; 
 System.out.println（Smallest Number：+ SmallestNumber（result））; 
 thelargest = LargestNumber（result）; 
 thesmallest = SmallestNumber（result）; 
 System.out.println（算术平均值
 + AirthmeticMean（结果，最小，最大））; 
 
} 
 
 public static int SmallestNumber（int [] series）{
 int thesmallest = series [0]; （int i = 1; i< series.length; i ++）{
 if（series [i]< thesmallest）{
 
 thesmallest = series [i] ; 
} 
} 
返回最小; 
} 
 
 public static int LargestNumber（int [] series）{
 int thelargest = series [0]; （int i = 1; i< series.length; i ++）{
 if（series [i]> thelargest）{
 
 thelargest = series [i] ; 
} 
} 
返回最大; 
} 
 
 public static float AirthmeticMean（int [] result，int thesmallest，
 int thelargest）{
 int sum = 0; （int i = 0; i< result.length; i ++）{
 sum + = result [i]; 
 
} 
 
 sum  -  =最小; 
 sum  -  =最大; 
 
 return（float）sum / result.length; 
} 
  

如何将此代码示例转换为ConsoleProgram（位于ACM中）图书馆）？
哪些部分必须更改或添加？

我开始：

 code> public class ArithmeticMean extends ConsoleProgram {
 
} 
  

但是我不知道下一步该怎么做。

解决方案

在acm库中没有主要方法，但需要使用以下构造：

  public void run（）{} 
  

以下是该图书馆的API http：//jtf.acm .org / javadoc / student /
选择acm.program package ConsoleProgram类并找到适当的方法
另请参见acm.io / class IOConsole

例如System.out.println（） - > println（）
扫描器（String input） - > readLine（String prompt）等。

其余的与你的代码一样。

好的，这里你是你的代码在acm：（有点丑，但工作正常） / p>

  import acm.program.ConsoleProgram; 
 
 public class StackOverflow extends ConsoleProgram 
 {
 private static final long serialVersionUID = 1L; 
 
 public void run（）
 {
 int q; 
 int p; 
 int最大; 
 int最小; 
 String input2 =; 
 String [] numbers = null; 
 
 println（输入号码列表）; 
 while（true）{
 String input = readLine（）; 
 if（input.equals（））
 break; 
 input2 + = input +; 
} 
 numbers = input2.split（）; 
 
 int [] result = new int [numbers.length]; （p = 0; p< numbers.length; p ++）
 {
 result [p] = Integer.parseInt（numbers [p]）; （q = 0; q< result.length; q ++）{
 print（）; 
 
} 
 
 
 println（result [q]）; 
} 
 
 println（最大的数字+最大的数字（结果））; 
 println（Smallest Number：+ SmallestNumber（result））; 
 thelargest = LargestNumber（result）; 
 thesmallest = SmallestNumber（result）; 
 println（算术平均值
 + AirthmeticMean（结果，最小，最大））; 
 
} 
 
 public static int SmallestNumber（int [] series）
 {
 int thesmallest = series [0]; （int i = 1; i< series.length; i ++）{
 if（series [i]< thesmallest）{
 
 thesmallest = series [i] ; 
} 
} 
返回最小; 
} 
 
 public static int LargestNumber（int [] series）
 {
 int thelargest = series [0]; （int i = 1; i< series.length; i ++）{
 if（series [i]> thelargest）{
 
 thelargest = series [i] ; 
} 
} 
返回最大; 
} 
 
 public static float AirthmeticMean（int [] result，int thesmallest，
 int thelargest）
 {
 int sum = 0; （int i = 0; i< result.length; i ++）{
 sum + = result [i]; 
 
} 
 
 sum  -  =最小; 
 sum  -  =最大; 
 
 return（float）sum / result.length; 
} 
 
} 
  

并以JavaApplet运行

I want ask a little question about my program.

This is my code sample:

public static void main(String[] args) {
    int q;
    int p;
    int thelargest;
    int thesmallest;

    Scanner input = new Scanner(System.in);
    System.out.println("Enter the list of number : ");
    String input2 = input.nextLine();

    String[] numbers = input2.split(" ");

    int[] result = new int[numbers.length];
    for (p = 0; p < numbers.length; p++) {
        result[p] = Integer.parseInt(numbers[p]);

    }

    for (q = 0; q < result.length; q++) {
        System.out.print("");
        System.out.println(result[q]);
    }

    System.out.println("Largest Number :  " + LargestNumber(result));
    System.out.println(" Smallest Number :  " + SmallestNumber(result));
    thelargest = LargestNumber(result);
    thesmallest = SmallestNumber(result);
    System.out.println("The Arithmetic Mean : "
            + AirthmeticMean(result, thesmallest, thelargest));

}

public static int SmallestNumber(int[] series) {
    int thesmallest = series[0];
    for (int i = 1; i < series.length; i++) {
        if (series[i] < thesmallest) {

            thesmallest = series[i];
        }
    }
    return thesmallest;
}

public static int LargestNumber(int[] series) {
    int thelargest = series[0];
    for (int i = 1; i < series.length; i++) {
        if (series[i] > thelargest) {

            thelargest = series[i];
        }
    }
    return thelargest;
}

public static float AirthmeticMean(int[] result, int thesmallest,
        int thelargest) {
    int sum = 0;
    for (int i = 0; i < result.length; i++) {
        sum += result[i];
    }

    sum -= thesmallest;
    sum -= thelargest;

    return (float) sum / result.length;
}

How can I convert this code sample to the ConsoleProgram (which is in the ACM library)? Which parts must I change or add?

I started with:

public class ArithmeticMean extends ConsoleProgram {

}

But I do not know what to do next.

解决方案

In acm library no main method though you need to use instead the following construction:

public void run() {}

Here is an API of this library http://jtf.acm.org/javadoc/student/ Select acm.program package ConsoleProgram class and find appropriate methods see also acm.io / class IOConsole

e.g. System.out.println() --> println() Scanner (String input) --> readLine(String prompt) etc.

the rest is the same as you in your code.

Ok, here you are your code in acm: (a bit ugly but works fine:)

import acm.program.ConsoleProgram;

public class StackOverflow extends ConsoleProgram
{
    private static final long serialVersionUID = 1L;

    public void run()
    {
        int q;
        int p;
        int thelargest;
        int thesmallest;
        String input2 = "";
        String[] numbers = null;

        println("Enter the list of number : ");
        while (true) {
            String input = readLine();
            if (input.equals(""))
                break;
            input2 += input + " ";
        }
        numbers = input2.split(" ");

        int[] result = new int[numbers.length];
        for (p = 0; p < numbers.length; p++) {
            result[p] = Integer.parseInt(numbers[p]);

        }

        for (q = 0; q < result.length; q++) {
            print("");
            println(result[q]);
        }

        println("Largest Number :  " + LargestNumber(result));
        println(" Smallest Number :  " + SmallestNumber(result));
        thelargest = LargestNumber(result);
        thesmallest = SmallestNumber(result);
        println("The Arithmetic Mean : "
                + AirthmeticMean(result, thesmallest, thelargest));

    }

    public static int SmallestNumber(int[] series)
    {
        int thesmallest = series[0];
        for (int i = 1; i < series.length; i++) {
            if (series[i] < thesmallest) {

                thesmallest = series[i];
            }
        }
        return thesmallest;
    }

    public static int LargestNumber(int[] series)
    {
        int thelargest = series[0];
        for (int i = 1; i < series.length; i++) {
            if (series[i] > thelargest) {

                thelargest = series[i];
            }
        }
        return thelargest;
    }

    public static float AirthmeticMean(int[] result, int thesmallest,
            int thelargest)
    {
        int sum = 0;
        for (int i = 0; i < result.length; i++) {
            sum += result[i];
        }

        sum -= thesmallest;
        sum -= thelargest;

        return (float) sum / result.length;
    }

}
