此处不允许注释android studio

Question

我收到此错误，但我不知道如何解决。错误显示此处不允许使用注释。错误在test

下

import android.app.Instrumentation;
import android.content.Context;
import android.support.test.InstrumentationRegistry;
import android.support.test.runner.AndroidJUnit4;

import org.junit.Test;
import org.junit.runner.RunWith;

import static org.junit.Assert.assertEquals;

/**
* Instrumentation test, which will execute on an Android device.
*
* @see <a href="http://d.android.com/tools/testing">Testing documentation</a>
 */
@RunWith(AndroidJUnit4.class)
public class ExampleInstrumentedTest {
private InstrumentationRegistry

@Test
public void useAppContext() throws Exception {
    // Context of the app under test.
    Context appContext = InstrumentationRegistry.getTargetContext();

    assertEquals("tabian.com.instagramclone", appContext.getPackageName());
}
}

如果我在InstrumentationRegistry之后添加分号，则会出现此错误Identifier expected

尝试一下：

import android.app.Instrumentation;
import android.content.Context;
import android.support.test.InstrumentationRegistry;
import android.support.test.runner.AndroidJUnit4;

import org.junit.Test;
import org.junit.runner.RunWith;

import static org.junit.Assert.assertEquals;

/**
* Instrumentation test, which will execute on an Android device.
*
* @see <a href="http://d.android.com/tools/testing">Testing documentation</a>
 */
@RunWith(AndroidJUnit4.class)
public class ExampleInstrumentedTest {
private InstrumentationRegistry registry;

@Test
public void useAppContext() throws Exception {
    // Context of the app under test.
    Context appContext = registry.getTargetContext();

    assertEquals("tabian.com.instagramclone", appContext.getPackageName());
    }
}
