我需要幫助,因爲我的腦細胞找不到這個程序出了什麼問題! 下面的代碼java中的最小值將不起作用
import java.util.*;
public class student{
public static void main (String []args)
{
Scanner sc=new Scanner(System.in);
System.out.println("enter number elements"); //asking the user to enter the number of integer items
int num=sc.nextInt();
int []myArray= new int[num];
int maxValue=myArray[0];
int minValue=myArray[0];
int i;
for(i=0; i<myArray.length;i++)
{System.out.print("Enter element"+(i+1)); //asking the user to enter the items
myArray[i]=sc.nextInt();
}
for(i=0; i<myArray.length;i++)
{System.out.print(myArray[i]); //displaying the elements
}
System.out.println(" ");
for(i=myArray.length-1; i>=0;i--)
{System.out.print(myArray[i]); //displaying the elements in a backward order
}
System.out.println(" ");
for(i=0; i<myArray.length;i++)
{if(i%2==1)
System.out.println(myArray[i]); //displaying the elements in odd indices
}
for(i=0; i<myArray.length-1;i++)
{ if(myArray[i]>maxValue)
{
maxValue= myArray[i]; //finding the maximum
}
}
System.out.println(maxValue+" "+(i+1));
for(i=1; i<myArray.length-1;i++)
{ if(myArray[i]<minValue)
{minValue= myArray[i]; //finding the minimum
}
}
System.out.println(+minValue+" "+(i+1));
System.out.println(myArray[0]); //displaying first item
System.out.println(myArray[myArray.length-1]); //displaying last item
for(i=0; i<myArray.length;i++)
{if(i%2==0)
{ myArray[i]= myArray[i]*-1; //multiplying items in even indices by -1
System.out.print(myArray[i]);}
}
}
}
程序在做什麼的評論,但最小值總是爲零,即使我沒有進入它...我想不出有什麼問題,所以我會很感激你的幫助!
注意:'for(i = 1; i

'int minValue = myArray [0];'我認爲他在開始時指定了 – evanwong
也請調整這個代碼。用不同的方法計算最大值和最小值 – tgoossens
