Java 程序,将偶数和奇数元素拆分为两个不同的列表
要将偶数和奇数元素拆分为两个不同的列表,Java 代码如下所示 −
示例
import java.util.Scanner; public class Demo{ public static void main(String[] args){ int n, j = 0, k = 0; Scanner s = new Scanner(System.in); System.out.println("Enter the number of elements required :"); n = s.nextInt(); int my_arr[] = new int[n]; int odd_vals[] = new int[n]; int even_vals[] = new int[n]; System.out.println("Enter the elements of the array(even and add numbers) :"); for(int i = 0; i < n; i++){ my_arr[i] = s.nextInt(); } for(int i = 0; i < n; i++){ if(my_arr[i] % 2 != 0){ odd_vals[j] = my_arr[i]; j++; } else { even_vals[k] = my_arr[i]; k++; } } System.out.print("The odd numbers in the array : "); if(j > 1){ for(int i = 0;i < (j-1); i++){ if(odd_vals[i]==1){ System.out.println("1 is niether even nor odd"); } else System.out.print(odd_vals[i]+","); } System.out.print(odd_vals[j-1]); } else { System.out.println("There are no odd numbers."); } System.out.println(""); System.out.print("The even numbers in the array : "); if(k > 1){ for(int i = 0; i < (k-1); i++){ if(even_vals[i]==1){ System.out.println("1 is niether even nor odd"); } else System.out.print(even_vals[i]+","); } System.out.print(even_vals[k-1]); } else { System.out.println("There are no even numbers in the array."); } } }
输出
Enter the number of elements required : Enter the elements of the array(even and add numbers) : The odd numbers in the array : 1 is niether even nor odd 9 The even numbers in the array : 2,4,6
控制台输入
5 1 2 4 6 9
一个名为‘Demo’的类包含主函数,该函数询问要在数组中存储的元素数量,并声明两个新数组,分别存储奇数值和偶数值。数组元素取自用户,并运行一个‘for’循环来检查数字是否能被 0 整除,即检查当数字除以 2 时的余数是否为 0。如果符合要求,则主数组中的那个数字将存储在偶数数组中,否则存储在奇数数组中。由于 1 既不是偶数也不是奇数,因此它在偶数或奇数数组中存储 1 的同时打印消息。
