如何在一定數量的答案後獲得不同的打印語句

Question

三個無效條目後，我需要第三次顯示不同的東西並恢復到第一個循環。另外我不知道如何使這個連續

do{ 
    System.out.print("Enter Rating(-1 to quit): "); 
    rating = input.nextInt(); 
    } 
    while (rating == 0 || rating == 1 || rating == 2 || rating == 3 || rating == 4); 
    System.out.print("Invalid entry. Please enter a whole number " 
    + "or enter -1 to quit: "); 
    rating = input.nextInt(); 

Answer 1

您可以使用while (rating < 0 || rating > 4)

Answer 2

你的意思呢？

/** 
    <P>{@code java Test}</P> 
**/ 
public class Test { 
    public static final void main(String[] ignored) { 
    int iterationCount = 5; 
    for(int i = 0; i < iterationCount; i++) { 
      if(i == 2) { //Index of 3 is 2 
      System.out.println("Printing something special on the third iteration!"); 
      //You could set i back to 0 here, if that's what you want... 
      } else { 
       System.out.println("Index " + i); 
      } 
     } 
    } 
} 

輸出：

[C:\java_code\]java Test 
Index 0 
Index 1 
Printing something special on the third iteration! 
Index 3 
Index 4
