如何从 Java 8 流内部抛出 CHECKED 异常？ - How can I throw CHECKED exceptions from inside Java 8 streams?

How can I throw CHECKED exceptions from inside Java 8 streams/lambdas?如何从 Java 8 流/lambda 内部抛出 CHECKED 异常？

In other words, I want to make code like this compile:换句话说，我想让这样的代码编译：

public List<Class> getClasses() throws ClassNotFoundException {     

    List<Class> classes = 
        Stream.of("java.lang.Object", "java.lang.Integer", "java.lang.String")
              .map(className -> Class.forName(className))
              .collect(Collectors.toList());                  
    return classes;
    }

This code does not compile, since the Class.forName() method above throws ClassNotFoundException , which is checked.这段代码不会编译，因为上面的Class.forName()方法抛出ClassNotFoundException ，它被检查了。

Please note I do NOT want to wrap the checked exception inside a runtime exception and throw the wrapped unchecked exception instead.请注意，我不想将已检查的异常包装在运行时异常中，而是抛出包装的未检查异常。 I want to throw the checked exception itself , and without adding ugly try / catches to the stream.我想抛出已检查的异常本身，并且不向流中添加丑陋的try / catches 。
