computer调用average(double x【】)方法，将数组a传递给参数x

你可以在代码中这样调用average(double x[])方法：

double[] a = {1.0, 2.0, 3.0, 4.0, 5.0};
double result = average(a);

这将创建一个double类型的数组a，然后将其作为参数传递给average方法。average方法将计算数组元素的平均值，并将结果返回到result变量中。

computer调用average(double x[])方法，将数组a //传递给参数x

假设你已经在计算机上编写了一个average x[])方法，那通过以下代码将数组传递给参数x：

double[] = {1.0, 2.0, 3.0, 4.0, 5.0};
double result = average(a);

在这个例子中，我们创建了一个名为a的double类型数组，并将一些值存储在其中。然后，我们调用average方法并将数组a传递给它。最后，average方法返回一个double类型的值，我们将其存储在result变量中。

完成下列代码interface ComputerAverage { public double average(double x[]);}class Gymnastics implements ComputerAverage { public double average(double x[]) { int count=x.length; double aver=0,temp=0; for(int i=0;i<count;i++) { for(int j=i;j<count;j++) { if(x[j]<x[i]) { temp=x[j]; x[j]=x[i]; x[i]=temp; } } } for(int i=1;i<count-1;i++) { aver=aver+x[i]; } if(count>2) aver=aver/(count-2); else aver=0; return aver; }}class School implements ComputerAverage { 【代码1】//重写public double average(double x[])方法,返回数组x[]的元素的算术平均}public class Estimator{ public static void main(String args[]) { double a[] = {9.89,9.88,9.99,9.12,9.69,9.76,8.97}; double b[] ={89,56,78,90,100,77,56,45,36,79,98}; ComputerAverage computer; computer=new Gymnastics(); double result= 【代码2】 //computer调用average(double x[])方法，将数组a传递给参数x System.out.print

以下是完成代码的方法：

interface ComputerAverage {
    public double average(double x[]);
}

class Gymnastics implements ComputerAverage {
    public double average(double x[]) {
        int count = x.length;
        double aver = 0, temp = 0;
        for (int i = 0; i < count; i++) {
            for (int j = i; j < count; j++) {
                if (x[j] < x[i]) {
                    temp = x[j];
                    x[j] = x[i];
                    x[i] = temp;
                }
            }
        }
        for (int i = 1; i < count - 1; i++) {
            aver = aver + x[i];
        }
        if (count > 2)
            aver = aver / (count - 2);
        else
            aver = 0;
        return aver;
    }
}

class School implements ComputerAverage {
    //重写public double average(double x[])方法,返回数组x[]的元素的算术平均
    public double average(double x[]) {
        int count = x.length;
        double sum = 0;
        for (int i = 0; i < count; i++) {
            sum += x[i];
        }
        return sum / count;
    }
}

public class Estimator {
    public static void main(String args[]) {
        double a[] = { 9.89, 9.88, 9.99, 9.12, 9.69, 9.76, 8.97 };
        double b[] = { 89, 56, 78, 90, 100, 77, 56, 45, 36, 79, 98 };
        ComputerAverage computer;
        computer = new Gymnastics();
        double result1 = computer.average(a); //computer调用average(double x[])方法，将数组a传递给参数x
        System.out.print("Gymnastics average: " + result1);
        computer = new School();
        double result2 = computer.average(b); //computer调用average(double x[])方法，将数组b传递给参数x
        System.out.print("School average: " + result2);
    }
}

在`School`类中，重写了`average`方法，计算并返回传递给该方法的数组`x[]`的算术平均值。在`Estimator`类的`main`方法中，先使用`Gymnastics`类计算数组`a[]`的平均值，再使用`School`类计算数组`b[]`的平均值，并将结果打印出来。
