试试这个：
码：
public class AverageElements {
private static double[][] array;
public static void main (String[] args){
// Initialize array
initializeArray();
// Calculate average
System.out.println(getAverage());
}
private static void initializeArray(){
array = new double[5][2];
array[0][0]=1.1;
array[0][1]=12.3;
array[1][0]=3.4;
array[1][1]=5.8;
array[2][0]=9.8;
array[2][1]=5.7;
array[3][0]=4.6;
array[3][1]=7.45698;
array[4][0]=1.22;
array[4][1]=3.1478;
}
private static double getAverage(){
int counter=0;
double sum = 0;
for(int i=0;i
for(int j=0;j
sum = sum+array[i][j];
counter++;
}
}
return sum / counter;
}
}
输出：
5.452478000000001
