How to give parameters when you run an activity

Hello, I'm a beginner android developer. I'd like to run an activity that explains the game. I want to include the game ID in that information, but how do I deliver the game ID to the activity? If you don't have a game ID, the game ID is so important that you don't have to show activity. What should I do?

This is an example when id is type int.

Intent intent = new Intent(FirstActivity.this, SecondActivity.class); Bundle b = new Bundle(); b.putInt("key", 1); //1 Put the ID in the part. intent.putExtras(b); //Put ID into int. startActivity(intent); finish(); // If you want to end the current activity and display the explanatory activity, you can add or subtract it.

In the activity describing the game,

Bundle b = getIntent().getExtras(); int value = b.getInt("key");

You can get it like this.
