Question

我正在编写一个程序，决定玩家是否有资格参加全明星赛。

我每次都得到“0”的输出。这是一个逻辑错误吗？别看了。

    import javax.swing.JOptionPane; 

public class IfElseBattingEverage 

{
   public static void main (String[] args)
   {
      int hits;
      int atBats; 
      int batAvg; 

      // get number hits from user

      hits = Integer.parseInt( JOptionPane.showInputDialog(null, "Enter number of hits") ); 

      // get number of at bats from user 

      atBats = Integer.parseInt( JOptionPane.showInputDialog(null, "Enter number of at Bats") );  

      // calcualte batting average 

      batAvg = ((hits/atBats)*100);
      System.out.println(batAvg);



      // decision if...else
      if (batAvg >= 30 )
      {
       System.out.println ("Congratulations! You are eligible for the all-star game, with a batting average of: " + batAvg + "%");
      }
      else
      {
      System.out.println ("Bummer! With a batting average of: " + batAvg + "% ,you are not eligible for the all-star game! Better luck next year!");
      }

   }
}

Answer 1

这可能是你的问题：

batAvg = ((hits/atBats)*100);

我会用这个：

batAvg = (100*hits/atBats);

hits/atBats是整数除法，主要导致0结果（如果点击＆lt; atBats）

这是一个逻辑错误吗？
