1.첫번째 방법 (내가 푼 방법)

package kr.co.aiai.app;

import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.TextView;

import androidx.appcompat.app.AppCompatActivity;

public class MainActivity7 extends AppCompatActivity {
       EditText etFirst;
       EditText etLast;
       TextView tvDisp;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main7);


        etFirst = findViewById(R.id.etFirst);
        etLast = findViewById(R.id.etLast);
        tvDisp = findViewById(R.id.tvDisp);
        Button btn = findViewById(R.id.btn);
        btn.setOnClickListener(view ->{
            myclick();
        } );
    }

    private void myclick() {
        String a = etFirst.getText().toString();
        int aa = Integer.parseInt(a);

        String b = etLast.getText().toString();
        int bb = Integer.parseInt(b);

        String str="";
        int count = aa;

        for(int i = 1; i <= bb-aa+1; i++){
            for(int j = 1; j <= count; j++){
                str += "*";
            }
            count++;
            str += "\n";
        }
        tvDisp.setText(str);
    }
}

1. for문을 돌릴 때 첫번째 for문 bb-aa +1 는 최대값 - 최솟값 +1 이다 그러면 별의 행의 수가 나온다.

2. 두번째 for문에서 변수 count는 aa를 담았다. 첫번째 별수는 입력하는 것에 따라 바뀌기 때문에 변수에 담아서

    for문을 돌려줘야 한다.
