我对编程很陌生，今天遇到了一个问题...我正在用控制台为高中制作一个 Hangman 游戏，但是问题是，如果我尝试读取 opcionMenu，则无法输入超过 1 个单词的电影，并且如果我手动更改 opcionMenu 的值，则变量 pelicula 会完美充电
谢谢
游戏尚未完成
代码如下:
package proyectoFinal;
import java.util.Scanner;
public class Proyecto {
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
int opcionMenu = 10;
String pelicula = "No hay pelicula";
char letra;
int espacios = 0;
int vidas = 6, aciertos = 0;
int cantidadPalabras, cantidadLetras;
String intento;
String mayuscula = "ABCDEFGHIJKLMNÑOPQRSTUVWXYZ";
String minuscula = mayuscula.toLowerCase();
String jugador;
System.out.println("Ingrese su nombre");
jugador = input.nextLine ();
while (opcionMenu != 0){
System.out.println("...............................................\n"
+ "\tOpcion \"1\" --- Ingresar Pelicula \n"
+ "\tOpcion \"2\" --- Jugar \n"
+ "\tOpcion \"0\" --- Salir \n"
+ "\t\t DEBE SER UN NUMERO.\n"
+ "...............................................");
opcionMenu = input.nextInt(); //HERE'S THE PROBLEM AND IN THE NEXT 5 LINES
switch (opcionMenu){
case 1 : System.out.println("Ingresar pelicula."); //Se ingresa la pelicula y la reconoce como mayusculas.
pelicula =input.next ().toUpperCase(); //SOLUCIONAR PARA QUE SE PUEDAN INGRESAR MAS DE 1 PALABRA
System.out.println("la pelicula es: " + pelicula + ".");
//System.out.println("\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n"
// + "\n\n\n\n\n\n\n\n\n");
//System.err.println("El nombre de la pelicula esta arriba ");
break;
case 2 : if(!"No hay pelicula".equals(pelicula)){
for (int i = 0; i < pelicula.length(); i++) {
letra = pelicula.charAt(i);
if(" ".equals(letra)){
espacios++;
}
}
cantidadPalabras = espacios + 1;
cantidadLetras = pelicula.length() - espacios;
System.out.println("La pelicula tiene " + cantidadPalabras + " palabras.");
System.out.println("Hay " + cantidadLetras + " letras.");
//Arranca El JUEGO
System.out.println("=================AHORCADO================= VIDAS = " + vidas + " ACIERTOS = " + aciertos);
dibujar(vidas);
System.out.println("Ingrese una letra (MINUSCULA) o la palabra completa (MAYUSCULAS) si desea arriesgar :");
intento = input.next();
for(int i=0; i< mayuscula.length(); i ++) {
for (int e = 0; i < intento.length(); e++){// DA ERROR... SOLUCIONAR

最佳答案
如果我理解正确的话，您希望能够扫描一部包含多个单词的电影。如果是这样，请更改:
pelicula =input.next ().toUpperCase();
至:
pelicula = input.nextLine().toUpperCase();
因为 input.next() 只会扫描第一个单词并忽略其余单词。
关于java - 扫描字符串时出错，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/32019105/
