This is because the caller of the Matcher does not know at runtime what the type is (because of type erasure with Java generics). It is down to the implementations to check the correct type. Parameters:

在Java中，assert关键字是从JAVA SE 1.4 引入的，为了避免和老版本的Java代码中使用了assert关键字导致错误，Java在执行的时候默认是不启动断言检查的（这个时候，所有的断言语句都 将忽略！），如果要开启断言检查，则需要用开关-enableassertions或-ea来开启。

Assertions (by way of the assert keyword) were added in Java 1.4. They are used to verify the correctness of an invariant in the code. They should never be triggered in production code, and are indicative of a bug or misuse of a code path. assert is a debugging tool that will cause the program to throw an AssertionFailed exception if the condition is not true. In this case, the program will throw an exception if either of the two conditions following it evaluate to false. Generally speaking, assert should not be used in production code Java assert not null . What is the Java assert and how it acts like null?

Assert that a string has valid text content; that is, it must not be null and must contain at least one non-whitespace character.

static void: assertSame(java.lang.String message, java.lang.Object expected, java.lang.Object actual) Asserts that two objects refer to the same object. The following examples show how to use junit.framework.Assert#assertNull() .These examples are extracted from open source projects.

Now, let us consider an example to demonstrate how to use assert in Java. To add assertions, we have to simply add an assert statement as follows: public void setup_connetion { Connection conn = getConnection (); assert conn != null; } Checks if a String is not empty ("") and not null.
