java获取偶数或奇数

Question

我有一个学校作业:我需要得到偶数或奇数，我做了一些东西来处理大于零的数字，但我需要找出负数是偶数还是奇数。

String[] evenodd = {" number is even", " number is odd"};
for(int i = 0; i < 100; i++)
{
    int x = i;
    while (x > 1) x = x - 2;
    System.out.println(i + evenodd[x]);
}

Answer 1

简单地使用模块 % 运算符

String[] evenodd = {" number is even", " number is odd"};
for(int i = 0; i < 100; i++)
{
int x;

if(i%2==0){
 x=0;/*pass 0 to print even number */
}else{
 x=1;/*pass 1 to print odd number*/
}
System.out.println(i + evenodd[x]);
}
