Make a String in java Global

I am an Android developer and I have made a string for generating a random 6-digit OTP which is there in the protected void onCreate(Bundle savedInstanceState) {, the first thing in a java program.:

String otp = new DecimalFormat("000000").format(new Random().nextInt(999999));
Toast.makeText(getApplicationContext(), "Your OTP is " + otp, Toast.LENGTH_SHORT).show();

I have another public void in my java program in which I have to call the OTP String but, I don't know how to do that.

Any type of help will be appreciated.

Solution

  • Define your String variable either as a class(static) variable or instance variable in your class.

    Sample solution

    public class Main{
   String otp; //Define your variable here


   public void method1(){

      //Now you can access the variable otp and you can make changes

   }

  public void method2(){

     //Now you can access the variable otp and you can make changes


  }

}
