我是Java的初学者,我正在学习本课程,对此需要一些帮助.基本上,用户将输入一个字符串,然后程序将仅在一行上打印出元音.
import java.util.Scanner;
class Main {
public static void main(String[] args) {
Scanner inp = new Scanner(System.in);
System.out.print("In:");
String word = inp.nextLine();
//write your code below
for(int whatsat = 0; whatsat < word.length(); whatsat++){
if (word.charAt(whatsat).equals("a")){ //how to declare mutiple letters?
System.out.print(word.charAt(whatsat));
}
}
}
}
最佳答案
我同意@Logan.您无需使用equals()来比较原始类型值(int,char,boolean等),只需使用简单的==表达式即可.
import java.util.Scanner;
class Main {
public static void main(String[] args) {
Scanner inp = new Scanner(System.in);
System.out.print("In:");
String word = inp.nextLine();
//write your code below
for(int whatsat = 0; whatsat < word.length(); whatsat++){
char c = Character.toLowerCase(word.charAt(whatsat));
if (c == 'a' || c == 'e'|| c == 'i' || c == 'o' || c == 'u'){
System.out.print(word.charAt(whatsat));
}
}
}
}
