偶数，奇数只有奇数的最小值和最大值

Question

提示用户输入数组的大小并允许用户将 输入整数值到数组中。检查每个元素是否为 或奇数。如果偶数，则打印求解元素（升序），如果奇数，则使用条件语句获得最大值和最小值 。输出结果。

public static void main(String[] args) { 

    Scanner sc = new Scanner(System.in); 
    System.out.println("Enter a number: "); 
    int n = sc.nextInt(); 
    int s[] = new int[n]; 
    for (int i = 0; i < n; i++) { 
     int e = sc.nextInt(); 
     s[i] = e; 
    } 

    Arrays.sort(s); 
    System.out.println("\nEven numbers in ascending order:"); 
    for (int j = 0; j < n; j++) { 

     if (s[j] % 2 == 0) { 
      System.out.print(s[j] + " "); 
     } 
    } 

    System.out.println("\nOdd numbers in descending order:"); 
    for(int j = (n -1); j >= 0; j--) { 
     if (s[j] % 2 == 1) { 
      System.out.print(s[j] + " "); 
     } 
    } 
} 

我不知道如何添加最小/最大为奇数

Answer 1

如果我理解你的问题，你可以试试这个：

int min = Integer.MAX_VALUE; // init min to the most max value 
int max = 0; // store max value 
for(int j = (n -1); j >= 0; j--) { 
    if (s[j] % 2 == 1) { 
     if (min > s[j]) { 
      min = s[j]; 
     } 
     if (max < s[j]) { 
      max = s[j]; 
     } 
     System.out.print(s[j] + " "); 
    } 
} 
System.out.println("min = " + min); 
System.out.println("max = " + max); 

全码：

public static void main(String[] args) throws Exception { 
    Scanner sc = new Scanner(System.in); 
    System.out.println("Enter a number: "); 
    int n = sc.nextInt(); 
    int s[] = new int[n]; 
    for (int i = 0; i < n; i++) { 
     int e = sc.nextInt(); 
     s[i] = e; 
    } 

    Arrays.sort(s); 
    System.out.println("\nEven numbers in ascending order:"); 
    for (int j = 0; j < n; j++) { 

     if (s[j] % 2 == 0) { 
      System.out.print(s[j] + " "); 
     } 
    } 

    //=========================================== 
    System.out.println("\nOdd numbers in descending order:"); 
    int min = Integer.MAX_VALUE; // init min to the most max value 
    int max = 0; // store max value 
    for(int j = (n -1); j >= 0; j--) { 
     if (s[j] % 2 == 1) { 
      if (min > s[j]) { 
       min = s[j]; 
      } 
      if (max < s[j]) { 
       max = s[j]; 
      } 
      System.out.print(s[j] + " "); 
     } 
    } 
    System.out.println(); // for new line 
    System.out.println("min = " + min); 
    System.out.println("max = " + max); 
} 

Answer 2

我的问题的解决方案是：

Scanner sc = new Scanner(System.in); 
while (true) { 
    System.out.print("Enter a Value: "); 
    int val = s.nextInt(); 

    if (val == 0) { 
     break; 
    } 
    if (val < min) { 
     min = val; 
    } 
    if (val > max) { 
    max = val; 
    } 
} 

System.out.println("min: " + min); 
System.out.println("max: " + max);
