我尝试了什么：
i试图make方法与我试图调用的方法相同
解决方案
你应该知道：
main是方法，它应该包含在（a）类定义中。String不提供getByte方法（它确实提供getBytes）。encrypt方法需要两个数组字节参数，即要加密的数据和加密密钥（您只传递数据）。
his is the code of the method i’m try To call is the encrypt method

This is the calling class the error shown in line 3
public static void main(String[] args) {
byte[ ] array = "going to encrypt ".getByte( );
byte[ ] arrayEnc = MARS.encrypt(array);
System.out.println("plain text: " + array);
System.out.println("Encrypted Text: "+ arrayEnc);
What I have tried:
i tried to make method that have the same of the method I'm trying to call
解决方案
You should know that:
mainis method, it should be included in (a) class definition.Stringprovide nogetBytemethod (it does providegetBytes, instead).- The
encryptmethod takes two array-of-byte arguments, namely the data to encrypt, and the encryption key (you are passing only the data).
这篇关于当我尝试在java中的main void中调用方法时，它说找不到方法的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
