average.java

我在学习JAVA的讲义

// 随机产生0~100之间的五个数，并求出它们的平均数。
public class Average
{
 public static void main(String args[])
 {
  int intNumber[];
  intNumber=new int[5];
  for(int i=0;i<intNumber.length;i++)
  {
   intNumber[i]=(int)(Math.random()*101);
   System.out.println(intNumber[i]+"");
  }
  System.out.println("\nThe Average is  "+GetAverage(intNumber));
 }

 static double GetAverage(int intNumber[]) 
 {
  int i,intTotal=0;
  double dblResult;
  for(i=0;i<intNumber.length;i++)
  {
   intTotal=intTotal+intNumber[i];
  }
  dblResult=(double)intTotal/intNumber.length;
  return dblResult;
	}
}
