Java程序查找给定数字是偶数还是奇数
偶数是可以被2整除的数字。因此，对给定数字执行％2运算，如果结果为0，则给定数字为偶数，否则给定数字为奇数。
示例
import java.util.Scanner;
public class EvenOrOdd {
public static void main(String args[]){
//从用户读取号码
Scanner sc = new Scanner(System.in);
System.out.println("Enter a number ::" );
int num = sc.nextInt();
//求偶数或奇数
if (num % 2 == 0){
System.out.println("Entered number is an even number");
} else {
System.out.println("Entered number is an odd number");
}
}
}输出1
Enter a number :: 9 Entered number is an odd number
输出2
Enter a number :: 8 Entered number is an even number
