我是 Java 和一般编程的新手。
在我的程序中，我使用 if 语句来读取特定的用户输入。但是，当我输入代码“75832”时，它会像输入“24231”一样处理它。此外，如果我输入了这些数字以外的任何内容，它会像输入“24231”一样处理它。我以前做过一些类似的其他基本程序，但我不知道我做错了什么或做错了什么。
有什么帮助吗？
static void gateMethod() throws InterruptedException
{
String stageCode;
int randomChunk;
Random generator = new Random();
Scanner input = new Scanner (System.in);
randomChunk = generator.nextInt(6);
System.out.println("Welcome to Datahub v.1");
System.out.println("\rEnter a phrase or number: ");
stageCode = input.nextLine();
if (stageCode.equals("24231"));
{
if(randomChunk == 0)
{
System.out.println("Data Chunk found! Please wait...");
Thread.sleep(2000);
System.out.println("Chunk 1/6:");
System.out.println("text");
Thread.sleep(2000);
System.out.println("");
gateMethod();
}
else if(randomChunk == 1)
{
System.out.println("Data Chunk found! Please wait...");
Thread.sleep(2000);
System.out.println("Chunk 2/6;");
System.out.println("text");
Thread.sleep(2000);
System.out.println("");
gateMethod();
}
else if(randomChunk == 2)
{
System.out.println("Data Chunk found! Please wait...");

System.out.println("Chunk 3/6:");
System.out.println("text");
