### Question:
MethodInjectingProvider extends MemberInjectingProvider<T> { static String getMethodSignature(Method method) { StringBuilder sb = new StringBuilder(); sb.append(method.getReturnType().getName()).append(' ').append(method.getName()).append('('); for (Type type : method.getGenericParameterTypes()) { sb.append(type.getTypeName()).append(','); } sb.append(')'); return sb.toString(); } MethodInjectingProvider(Provider<T> delegate, DefaultInjector injector); @Override String getName();  }### Answer:
@Test public void testGetMethodSignature() throws Exception { Method methodInt = Class1.class.getDeclaredMethod("methodInt"); Method methodArgs = Class1.class.getDeclaredMethod("methodArgs", int.class, Object.class); String signature1 = MethodInjectingProvider.getMethodSignature(methodInt); assertEquals("int methodInt()", signature1); String signature2 = MethodInjectingProvider.getMethodSignature(methodArgs); assertEquals("void methodArgs(int,java.lang.Object,)", signature2); }
