java - 对于安全随机类型，方法 nextInt 未定义

Question

我尝试使用此代码生成随机数，但不断收到此错误

Exception in thread "main" java.lang.Error: Unresolved compilation problem: 
    The method nextInt(int) is undefined for the type SecureRandom

    at SecureRandom.main(SecureRandom.java:18)

这是我尝试过的

public class SecureRandom {

    public static void main(String[] args) {
    SecureRandom randomNumbers = new SecureRandom();
    for (int count = 1; count <=20; count++) {

        int face = 1+randomNumbers.nextInt(6);
        System.out.printf( " %d" , face);

        if (count %5 ==0) {
        System.out.println();
        }

    }

    }

}

编译器正在根据您定义的类解析SecureRandom。您应该更改类名以避免与 java.security.SecureRandom 冲突。
