Java，在我的代码中只有第一个for语句有效

Question

刚刚开始学习Java和编程，我需要输入50个字符，并计数和显示元音，辅音，数字和特殊字符。在我的元音的第一个for语句之后，它不再正常工作了，我不知道为什么它不工作，所以任何提示都会有所帮助，谢谢。

import java.util.Scanner;
public class CharArray50 {
static Scanner scanner = new Scanner(System.in);
public static void main() {
int z = 0;
do {
String Str50 = "";
int Vowelsnum = 0;
int Consonantsnum = 0;
int Digitsnum = 0;
int SpecialCharnum = 0;
System.out.print("Input 50 Characters Max: ");
Str50 = scanner.nextLine();
Str50 = Str50.toLowerCase();
System.out.println("Characters: " + Str50);
System.out.print("Vowels: ");
for (int x = 0; x < Str50.length(); x++) {
char Char50 = Str50.charAt(x);
if ((Char50 == 'a')
|| (Char50 == 'e')
|| (Char50 == 'i')
|| (Char50 == 'o')
|| (Char50 == 'u')) {
Vowelsnum += 1;
System.out.print(" " + Char50);
}
}
System.out.println("nNumber of Vowels: " + Vowelsnum);
System.out.print("Consonants: ");

Answer 1

if语句后面有分号:)
