How can we get one value back of two values in Android java?

March 25, 2023

How can we get one value back of two values? For example, if the user writes 100, how can we replace 100 with 50+50 in the text box? That is, suppose the user types 100 and on pressing the button, instead of 100, the text box should show 50+50 or 75+25 and so on، which is equal to 100 .A friend suggest me but I want to provide a low and a high value to the user. That is, if the user writes 100, it should be displayed as 75+25 or 80+20 etc. Thanks

    int customerInput = 100; //getvalue from user
        int splitValue = customerInput/2;
       saif.setText(splitValue+"+"+splitValue);

>Solution :

What are the lows and highs that you need?

In your example it’s 1/4 and 3/4 so that would give you:

  int customerInput = 100; //getvalue from user
  int splitValue1 = customerInput/4;
  int splitValue2 = (customerInput/4)*3;
  saif.setText(splitValue+"+"+splitValue);

If you need it to be random you can use the Java function

int random = Random.nextInt(n)

This returns a random int in the range [0, n-1].
So in your case you would need a random number between 0 and 100

int customerInput = 100; //getvalue from user 
int random = new Random().nextInt(100); // [0, 100]
int random2 = 100 - random; // the other percent of your number
saif.setText(random+"+"+random2);
