Syntax error on token ";", { expected after this token
提问by silverkid
why is there syntax error on this line ( shown below )
为什么这一行有语法错误（如下所示）
package org.temp2.cod1;
import java.security.*;
import javax.crypto.*;
import javax.crypto.spec.*;
import java.io.*;
public class Code1 {
byte[] plaintext = new byte[32]; // <<<<<<<<<<<<<<<<<<<<<<<<<< syntax error
for (int i = 0; i < 32; i++) {
plaintext[i] = (byte) (i % 16);
}
byte[] key = new byte[16];
SecureRandom r = new SecureRandom();
r.nextBytes(key);
Cipher c = Cipher.getInstance("AES");
SecretKeySpec k = new SecretKeySpec(key, "AES");
c.init(Cipher.ENCRYPT_MODE, k);
byte[] encryptedData = c.doFinal(plaintext);
}
}

You forgot the entry point method declaration. Try adding:
您忘记了入口点方法声明。尝试添加：
public static void main(String[] args) {
before the line where you got the error.
在出现错误的行之前。
回答by Bozho
your code should be inside a method. It appears to me that you have skipped the public void method(..) {line
你的代码应该在一个方法中。在我看来你跳过了这public void method(..) {条线
