修改后的代码现在无法运行，收到语法错误

Question

所以我有了这段代码，并试图对其进行编辑以添加一个额外的按钮，但现在它不想运行。它和我以前的完全一样。我删除了新代码，但现在此代码不想运行。有小费吗？我在moveTo（activity）变量上遇到错误。与分号和方括号有关吗？我真的很困惑为什么它不起作用。

public class Main2Activity extends AppCompatActivity {

private Button B3;
private Button B4;
private Button B5;
private Button B6;
private Button B7;
private Button B25;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main2);

    B3 = findViewById(R.id.button3);
    B3.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            moveToDanceScheduleMenu();
        }
    });

    B4 = findViewById(R.id.button10);
    B4.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            moveToWhatsOn();
        }
    });

    B5 = findViewById(R.id.button11);
    B5.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            moveToMainResultsMenu();
        }
    });

    B6 = findViewById(R.id.button12);
    B6.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            moveToSponsorsMenu();
        }
    });

    B7 = findViewById(R.id.button6);
    B7.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            moveToRulesAndRegs();
        }
    });

    B25 = findViewById(R.id.button18);
    B25.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            moveTomusic_submission();

        }
    });

private void moveTomusic_submission () {
    Intent intent = new Intent(Main2Activity.this, music_submission.class);
    startActivity(intent);
}

private void moveToDanceScheduleMenu () {
    Intent intent = new Intent(Main2Activity.this, DanceScheduleMenu.class);
    startActivity(intent);

        startActivity(intent);
