输入:
10
3 1 45 67 2 56 89 22 11 69
输出(我想要的):
2 22 56
89 69 67 45 11 3 1
我想按升序打印偶数数字,按降序打印奇数而不使用集合,因为我不知道收集。在这里帮助我,我如何按降序打印奇数我能够直到偶数
代码:
import java.util.Arrays;
import java.util.Scanner;
class T {
public static void main(String[] args) {
// TODO Auto-generated method stub
Scanner sc = new Scanner(System.in);
System.out.println("enter a number");
int n = sc.nextInt();
int s[] = new int[n];
int i;
for (i = 0; i < n; i++) {
int e = sc.nextInt();
s[i] = e;
}
Arrays.sort(s);
for (int j = 0; j < n; j++) {
if (s[j] % 2 == 0) {
System.out.println(s[j]);
}
}
}
}

// Even in ascending
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] + " ");
}
}
// Odd in descending
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] + " ");
}
}
}

Even numbers in ascending order:
2 22 56
Odd numbers in descending order:
89 69 67 45 11 3 1

由于数组已经排序(按升序排列),请先打印出偶数。
然后以相反的方向(desc顺序)遍历数组,并打印出奇数。

反转标记并使用相同的循环打印:
