請幫我用java編程錯誤

Question

我是新來這個java語言，請幫我出：

import java.util.Scanner; 

class MyClass { 

    public static void main(String[] args){ 
     System.out.println("give any number"); 
     Scanner n = new Scanner(System.in); 
     for(int x = 0; n < x; x++){ 
      if(x==3){ 
       System.out.println("fizz"); 
       x = x+1; 
      } else if(x==5){ 
       System.out.println("buzz"); 
       x = x+1; 
      } else { 
       System.out.println("x"); 
       x = x+1; 
      } 
     } 
    } 
} 

Answer 1

1）需要從Scanner

得到int值變化

Scanner scanner = new Scanner(System.in); 
     int n = scanner.nextInt(); 

2.）在for loop更改比較中，x從0開始，從而改變相應

變更

for (x = 0 ; x < n ; x++) { 

代碼如下

public static void main(String[] args) { 
     int x = 0; 
     System.out.println("give any number"); 
     Scanner scanner = new Scanner(System.in); 
     int n = scanner.nextInt(); 
     for (x = 0 ; x < n ; x++) { 
      if (x == 3) { 
       System.out.println("fizz"); 
       x = x + 1; 
      } else if (x == 5) { 
       System.out.println("buzz"); 
       x = x + 1; 
      } else { 
       System.out.println("x"); 
       x = x + 1; 
      } 
     } 
    } 

輸出

give any number 
3 
x 
x 

Answer 2

import java.util.Scanner; 

class MyClass { 

public static void main(String[] args) 
{ 
    int x=0; 
    int i=1; 
    System.out.println("give any number"); 
    Scanner n = new Scanner(System.in); 
    i= n.nextInt(); 
    for(x=0;i<x;x++) 
    { 
     if(x==3) 
     { 
      System.out.println("fizz"); 
      x=x+1; 
     } 
     else if(x==5) 
     { 
      System.out.println("buzz"); 
      x=x+1; 
     } 
     else 
     { 
      System.out.println("x"); 
      x=x+1; 
     } 
    } 
} 
} 

Answer 3

你必須得到Scanner你的價值int n = num.nextInt();讓掃描儀值INT。

Scanner num = new Scanner(System.in); 
     int n = num.nextInt(); 
     for(x=0;n<x;x++) 

Answer 4

你提到你的expected output 做..

import java.util.Scanner; 

class MyClass { 

    public static void main(String[] args) {    
      int x = 0; 
      System.out.println("give any number"); 
      Scanner num = new Scanner(System.in); 
      int n = num.nextInt(); 
      for (x = 1; x <= n; x++) { 

       if (x == 3) { 
        System.out.println("fizz"); 
       } else if (x == 5) { 
        System.out.println("buzz"); 
       } else { 
        System.out.println(x); 
       } 

      } 
    } 
} 

輸出：

give any number 
5 
1 
2 
fizz 
4 
buzz
