对,所以为什么Java的想出这个错误:爪哇 - 最高,最低和平均
异常在线程“主要” java.lang.Error的:未解决的问题,编译: 类型不匹配:不能从双转换为int
在rainfall.main(rainfall.java:38)
从这:
public class rainfall {
/**
* @param args
*/
public static void main(String[] args)
{
int[] numgroup;
numgroup = new int [12];
ConsoleReader console = new ConsoleReader();
int highest;
int lowest;
int index;
int tempVal;
int minMonth;
int minIndex;
int maxMonth;
int maxIndex;
System.out.println("Welcome to Rainfall");
// Input (index now 0-based)
for(index = 0; index < 12; index = index + 1)
{
System.out.println("Please enter the rainfall for month " + index + 1);
tempVal = console.readInt();
while (tempVal>100 || tempVal<0)
{
System.out.println("The rating must be within 0...100. Try again");
tempVal = console.readInt();
}
numgroup[index] = tempVal;
}
lowest = numgroup[0];
highest = numgroup[0];
int total = 0.0;
// Loop over data (using 1 loop)
for(index = 0; index < 12; index = index + 1)
{
int curr = numgroup[index];
if (curr < lowest) {
lowest = curr;
minIndex = index;
}
if (curr > highest) {
highest = curr;
maxIndex = index;
}
total += curr;
}
float avg = (float)total/numgroup.length;
System.out.println("The average monthly rainfall was " + avg);
// +1 to go from 0-based index to 1-based month
System.out.println("The lowest monthly rainfall was month " + minIndex + 1);
System.out.println("The highest monthly rainfall was month " + maxIndex + 1);
System.out.println("Thank you for using Rainfall");
}
private static ConsoleReader ConsoleReader() {
return null;
}
}
下一次请格式化你的代码(使用编辑器上方的'101010'按钮)。此外,如果您明确标记发生错误的代码行,则会有所帮助... – 2010-05-17 10:34:24
