使用if...else..判斷：
import java.util.Scanner;
public class test {
public static void main(String[] args) {
int mouth;
while(1==1){
System.out.println(請(qǐng)輸入月份：);
mouth=new Scanner(System.in).nextInt();
if (mouth==0) {
System.out.println(一月);
}else if (mouth==1) {
System.out.println(二月);
}else if (mouth==2) {
System.out.println(三月);
}else if (mouth==3) {
System.out.println(四月);
}else if (mouth==4) {
System.out.println(五月);
}else if (mouth==5) {
System.out.println(六月);
}else if (mouth==6) {
System.out.println(七月);
}else if (mouth==7) {
System.out.println(八月);
}else if (mouth==8) {
System.out.println(九月);
}else if (mouth==9) {
System.out.println(十月);
}else if (mouth==10) {
System.out.println(十一月);
}else if (mouth==11) {
System.out.println(十二月);
}else {
System.out.println(請(qǐng)重新輸入月份 );
break;
}
}
}
}
使用switch：
import java.util.Scanner;
public class test{
public static void main(String[] args) {
int mouth;
do{
System.out.println(請(qǐng)輸入月份：);
mouth=new Scanner(System.in).nextInt();
switch(mouth){
case 0:
System.out.println(一月);
break;
case 1:
System.out.println(二月);
break;
case 2:
System.out.println(三月);
break;
case 3:
System.out.println(四月);
break;
case 4:
System.out.println(五月);
break;
case 5:
System.out.println(六月);
break;
case 6:
System.out.println(七月);
break;
case 7:
System.out.println(八月);
break;
case 8:
System.out.println(九月);
break;
case 9:
System.out.println(十月);
break;
case 10:
System.out.println(十一月);
break;
case 11:
System.out.println(十二月);
break;
default:
System.out.println(請(qǐng)重新輸入月份);
break;
}
}while (mouth>=0&&mouth<=11);
}
}
