### Question:
ClassLoader { public KClass loadClass(String name) { KClass cache = MetaSpace.findClass(name); if (cache != null) { return cache; } KClass clazz = doLoadClass(name); doRegister(clazz); return clazz; } ClassLoader(String name, Entry entry); void loadPrimitiveClass(String name); void loadPrimitiveArrayClass(String name); KClass loadClass(String name); void doRegister(KClass clazz); KClass doLoadClass(String name); KClass doLoadClass(String name, ClassFile classFile); KMethod map(Method cfMethod); KField map(Field field); String getName();  }### Answer:
@Test public void test_object() { KClass kClass = classLoader.loadClass("java/lang/Object"); assertNotNull(kClass); }
@Test public void test_hello() { KClass kClass = classLoader.loadClass("Hello"); assertNotNull(kClass); }
@Test public void test_onjava8_passobject() { KClass clazz = classLoader.loadClass("PassObject"); assertNotNull(clazz); }
@Test public void test_system() { KClass kClass = classLoader.loadClass("java/lang/System"); assertNotNull(kClass); }
