//第一行和第二行代碼互換位置（import引入包要放在java文件的開頭） import?java.util.Scanner; public?class?Hello?{ ????public?static?void?main(String[]?args)?{ ???????? ????} }2020-07-06
最后一個最好，簡單
2020-07-06
System.out.println(one%2==0?"one是偶數":"one是奇數");
2020-06-26
public class HelloWorld {
? ? public static void main(String[] args) {
int one = 20 ;
int x=one%2;
/*String z=(x==0)?"這是偶數":"這是奇數";
System.out.println(z);*/
if(x==0) {System.out.println("這是偶數");}
if(x==1){System.out.println("這是奇數");}
? ? ? ??
? ? }
}
emmm? y1s1 456看的不是很明白

//你的代碼不符合題意，應該像下面這樣寫 public?class?HelloWorld?{ ????public?static?void?main(String[]?args)?{ ????????int?one?=?20?; ????????if(one%2==0){ ????????????System.out.println(one?+?"是偶數"); ????????}else{ ????????????System.out.println(one?+?"不是偶數"); ????????} ????} }
