Long Comments in JAVA

Is it ok if I use Comments with long dashes like this to seperate my code?

Will it affect the performance of my application or any other aspect?I was thinking to do this in all of my activities.

   radioSection.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {
          @Override
          public void onCheckedChanged(RadioGroup group1, int checkedId1) {
              switch (checkedId1) {
                  case R.id.rbSr:
                      section = "SR";
                      break;
                  case R.id.rbJr:
                      section = "JR";
                      break;
              }
          }
      });
//----------------------------------------------------------------//----------------------------------------------------------------
        db = FirebaseFirestore.getInstance();
        firebaseAuth = FirebaseAuth.getInstance();
//----------------------------------------------------------------//----------------------------------------------------------------
   next.setOnClickListener(new View.OnClickListener() {
         @Override
         public void onClick(View v) {
             String name1 = FullName.getText().toString().trim();
             String name2 = DOB.getText().toString().trim();

            if(radioGender.getCheckedRadioButtonId() == -1 || radioSection.getCheckedRadioButtonId() == -1 || name1.isEmpty() || name2.isEmpty() || subsection.equals("Select Sub-Section") || subject.equals("Select Subject")){
                 Toast.makeText(ADDdetails.this, "Enter Details", Toast.LENGTH_SHORT).show();
             }else{
                 updateUserDetails();
             }
         }
     });

By definition, comments don't affect execution of the program.

From this tutorial from Oracle,
> Comments are ignored by the compiler but are useful to other programmers.

Whether it's OK or not from a stylistic perspective is a matter of opinion.

For your own personal use perspective it'll be fine. The blocks of commented code will be ignored. When it comes to commenting in a team environment it's important to be uniform with what the team wants.

It will not affect application, but it will affect compiler because it has to extract comments from code.
